lightweight. They also are expected to heighten efficiency and satisfy
uses in special environment.
Publishing a catalogue to introduce our entire product line is
especially meaningful under such circumstances. This is an
improved version of the previous catalogue; products are
categorized, and each product category has two sections. The first
section contains an explanation of products and dimension tables for
easy selection. The second half is a technical explanation including
results of the latest experiments and research to assist thorough
technological discussion. Last, Other, whose pages are in color,
explains special environments and lubrications such as grease,
which are general issues for NSK precision products.

A-I Selection Guide to NSKLinear GuidesA-I-1 Structure of NSK Linear Guides By avoiding structural complexity, and by reducing the number of components, we not only enhanced theprecision of linear guides, but also are able to keep costs low. We have added NSK's patented unique structuralfeature to the original invention (Fig. I-1-1). This contributes to higher precision and lower prices.NSK linear guide consists of a rail and a ball slide (Fig. I-1.2). The balls roll on the grooves on the rail and theball slide, and scooped up by the end caps attached to both ends of the ball slide. Then, the balls go through theopening made in the ball slide, and circulate back to the other end.
A-I-2 Characteristics of NSK Linear GuidesThe use of a unique offset gothic arch groove (Fig. I-13) allows the NSK linear guides to satisfy groove designsrequired for specific purposes.The precise measurement of the ball groove leads to stable production of highly accurate linear guides andinterchangeable linear guides. (Fig. I-14).Such technologies eusure the feature of NSK linear guides outlined below.
(1) Abundant in type for any purpose* Various series are available, and their ball slide models and size categories are standardized to satisfy any
requirement. Our technology, polished by abundant experience in the use of special materials and surfacetreatments, meets the customers most demanding expectations.
(2) High precision and quality* High precision and quality come from our superb production and measuring technologies, strengthened by
extensive experience in antifriction rotary bearings and ball screw production. Our quality assurance extends tothe smallest components.
(3) High reliability and durability* Logical simplicity in shape, along with stable processing, maintains high precision and reliability.* Super-clean materials, our advanced heat treatment and processing technologies increase product durability.
(4) Component compatibility shortens delivery time* Interchangeable parts: The adoption of the gothic-arch groove which makes measuring easy, and a new
reliable quality control method has made random-matching of the rails and the ball slides possible. The partsare stocked as standard products, thereby reducing delivery time.
(5) Patented static load carrying capacity (shock-resistance)* When a super-high load (impact) is applied, our gothic-arch groove spreads the load to surfaces which usually
do not come into contact. This increases shock resistance (Fig. I-15).

A-I-2.1 Types and Characteristics of NSKLinear Guides
We have abundant types of linear guide for anypurpose to accommodate the most special needs ofthe users.
(1) Types of series and classification byfeature
A There are two types of NSK linear guide: 1. Rigidity and load carrying capacity against the
vertical direction are greater than the rigidityand load carrying capacity against the load fromthe lateral direction (high vertical load carryingcapacity type);
2. Load is equally distributed to four directions (four-directional iso-load carrying capacity type)
A There are three types of NSK linear guide by thelength of the ball slide 1. Standard length ball slide with high-load
carrying capacity;
2. Long ball slide with super-high load carryingcapacity;
3. Short ball slide for mid-level load carryingcapacity.
A Four-row ball grooves linear guide has two types: 1. Self-aligning capability- which absorbs certain
amount of installation error;2. High moment carrying type with great moment
rigidity. A Two-row ball grooves linear guide has mid-level
moment rigidity.A Interchangeable parts: Thanks to the ease of
measuring gothic-arch groove, we can preciselymanufacture rails and ball slides, and thus, youcan purchase the rails and the ball slidesindividually and assemble them randomly.
A Stainless steel is also available as standardmaterial for some series.

A The contact angle between the ball and the raceway is set
at 45 degrees. Therefore, load carrying capacity and
rigidity are equal in vertical and lateral directions.
A Balls contact at four points during high preload. The four-
row ball groove supports the load from vertical and lateral
directions. This makes the linear guide highly rigid.
A Rigidity against moment load is great due to the DB
contact (at time of light preload) or the four-point contact
(at time of high preload)
A Sliding resistance slightly increases, absorbing vibration to
the rail longitudinal direction due to the four-point contact
at time of high preload.
A Ideal for heavy cutting machine tools.
A Strong against shock load
A The contact angle between the ball and the raceway is setat 50 degrees. The load carrying capacity against verticaldirections, which is prevalent in most operations, increaseswith this design
A The rail is wide. This contributes to a high rolling moment
carrying capacity and to great moment rigidity when only
single linear guide is in use
A Balls contact at two points in the offset gothic arch groove,
keeping friction small.
A High resistance against shock load
A Standardized interchangeable assemblies allows separate
purchase of rails and ball slides.
A Extremely thin, and wide in shape. This is ideal in use ofonly single linear guide.

Priorto calculating the linear guide's life expectancy, selectan appropriate size of the linear guide. Below is an easy selection method. After selectingthe size by this method, check the life by using the"A-II-3.2: Calculation of Life Expectancy."
(1) Select the size based on the space to beused.
Select a linear guide which matches the space inwhich it is used. Select directly from the "A-I-5:Model Number and Dimension Table."
(2) Select the size based on the ball screwsize.
Always select a linear guide which matches the sizeof the screw shaft diameter, or the size closest to it,e.g., when the ball screw shaft diameter is 32, selectlinear guide type LH30, or LH35.
(3) Select the size based on the estimatedload on one ball slider.
Most linear guides are table-shaped and have tworails and four ball slides for an axis.Assuming the linear guide is this type, calculate arough load per ball slide using the formula below:
(3.1)
P : Load per ball slide
Kp : Load position coefficient
F : LoadLoad position coefficient Kp should be found for eachload by the proportion of the distance between ballslide span and load point, and the distance betweenrail span and load point.
(A) When load is vertical(Fig. I-31)
(B) When the load is in the axial direction(Fig. I-32)
(C) When the load is lateral to the rail(Fig. I-33)
The load position is normally the coordinate position.Disregard + or - symbols, and use absolute values.
Upon obtaining the load value P per ball slide byusing the above position coefficient Kp in (3.1), selectthe matching size (model number) from Fig. I-34.Because the above calculation formula is a simpleone, the load obtained by the above formula may belarger than the actual case if the value of Kp is over 1,or in the case three patterns (A), (B), and (C) arecombined. In such case, the size to be selected (model number) should be larger; however, the lifewill be longer.

A-I-5 Model Number and Dimension Table ofNSK Linear Guides
A-I-5.1 LH Series
(1) High self-aligning capability (rolling direction) Same as the DF combination in angular contact bearings,
self-aligning capability is high because the cross point of
the contact lines of balls and grooves comes inside,
reducing moment rigidity.
This increases the capacity to absorb the error of
installation.(2) High load carrying capacity to vertical
directionThe contact angle is set at 50 degrees, increasing load
carrying capacity as well as rigidity in vertical direction.(3) High resistance against impact load
The bottom ball groove is formed in gothic-arch and the
center of the top and bottom grooves are offset as shown
in Fig.I-52. The vertical load is generally carried by the
top rows, at where balls are contacting at two points.
Because of this design, the bottom rows will carry load
when a large impact load is applied vertically as shown in
Fig.I-53. This assures high resistance to the impact load.(4) Highly accurate as shown in Fig. I-5.4, fixing the master rollers is easy thanks to the
gothic-arch groove. This makes easy and accurate
measuring of ball grooves. (5) Easy to handle, and designed with safety in
mind.Balls are retained in the retainer, therefore they do not
fall out when the ball slider is withdrawn from the rail.(6) Abundant models and sizes
Each series has various models of ball slides, rendering
the linear guide available for numerous uses.(7) Interchangeable series is available (prompt
delivery) The series enables random matching of rails and ball
slides (interchangeability) for prompt delivery.

A-I-5.2 LS Series
(1) High self aligning capability (rolling direction)Same as the DF combination in angular contact bearings,self-aligning capability is high because the cross point ofthe contact lines of balls and grooves comes inside,reducing moment rigidity. This increases the capacity toabsorb the error of installation.
(2) High load carrying capacity to verticaldirection
The contact angle is set at 50 degrees, increasing loadcarrying capacity as well as rigidity against the load invertical direction.
(3) High resistance against impact loadThe bottom ball groove is formed in gothic-arch and thecenter of the top and bottom grooves are offset as shownin Fig. I-56. The vertical load is usually carried by top 2rows at where balls are contacting at two points. Becauseof this design, the bottom rows will carry the load when alarge impact load is applied as shown in Fig. I-57. Thisassures high resistance to the impact load.
(4) Highly accurateAs shown in Fig. I-58, fixing the measuring rollers issimple thanks to the gothic-arch groove. This makes easyand accurate measuring of ball- grooves.
(5) Easy to handle, and designed with safety inmind.
Balls are retained in the retainer and do not fall out whenthe ball slide is withdrawn from the rail.
(6) Abundant models and sizes come in series.Each series have several ball slide models, rendering thelinear guide available for numerous uses. The LS Seriesalso has standardized long stainless- steel rail (maximum:3 500 mm).
(7) Interchangeable series is available (shortdelivery time)
The series enables random matching of rails and ball
slides (interchangeability) for prompt delivery.
