Thermal Characteristics of LM Rail and LM Block Materials
• Specific heat capacity : 0.481 J/(g-K)• Thermal conductivity : 20.67 W/(m-K)• Mean linear expansion coefficient : 11.8×10-6/:
LM rail overall length LM rail bend
Mean value Fluctuation
• The overall length and bend data indicate changes that occurred when the samples were heated to 150: for 100h, thencooled to normal temperature.
• The samples were the high-temperature, standard, and stainless steel models of HSR25+580L.
A special treatment to maintain dimensional stability minimizes dimensional variations due to heating and cooling.
The grease chosen for the new LM Guide provides smoother ball rolling, less subject to changes in rolling resistance andfluctuations (scratchy movement). This property holds good over the entire temperature range, from normal to high.
The data above was obtained with HSR25M1R1C1 used as the sample.

Precautions on the Use of the THK High-temperature LM Guide
[Operating Temperature of High-temperature LM Guide]
Permissible up to 150:.
[Choosing the Right Type of High-temperature LM Guide]
To choose the right type of guide for your application, please refer to Chapter 4, Selecting the Correct
Type of LM Guide, in the General Catalog. (The selection procedures are the same as used for the
standard LM Guide.) For the temperature coefficient fT, please refer to graphs presented in the same
chapter of the General Catalog. Use 1.0 as the hardness coefficient fH.
[Dimensional Accuracy of High-temperature LM Guide]
Although the High-temperature LM Guide is built to the same dimensional accuracy as that of the
standard LM Guide, yet at high temperatures the accuracy changes by an amount equal to the thermal
expansion.
[Calculating the Linear Expansion of the High-temperature LM Guide]
The thermal expansion of High-temperature LM Guide can be calculated from the following equation:
L2-1 = α ( t2-t1) L1
L2-1 : thermal expansion due to heating (mm)
α : linear expansion coefficient (see the table below)
t2 : heating temperature (:)
t1 : normal temperature (:)
L1 : length at normal temperature (mm)
High-temperature 304 LM Guide SS400 FC25 (SUS304) Aluminum
Linear expansion coefficient 11.8 11.2~11.3 8.6~8.7 16.4 23
Table 1 Linear Expansion Coefficients of Various Materials (×10-6/:) (Other values than those of THK High-temperature LM Guide are cited from Practical Design Part II (Nikkan Kogyo Shimbun)
Note: Special care must be taken when installing the High-temperature LM Guide on a material with a thermal expansion coefficient which significantly differs from that of the Guide, or where the emperature distribution is not uniform even if the linear expansion coefficients are the same. These conditions can bend the rails and vary the preload on the LM Guide. (For the LM Guide preload, see the General Catalog.)
• 4 •
[Grease Used in High-temperature LM Guide]
Unless otherwise specified, fluorine-based grease is sealed into the High-temperature LM Guide as the
standard lubricant. The physical properties of the High-temperature LM Guide grease are as shown
below.
(Mixing other greases and lubricating oils can degrade performance. If your application requires use of the Guide under a vacuum, please contact THK.)
[Changes in Sliding Resistance Due to Grease and Seals]
The LM Guide sliding resistance due to high-temperature grease and seals tends to increase in
proportion to the temperature rise.
[Lubrication of High-temperature LM Guide]
Feed grease to the Guide every 100 km of running distance, as a rule. The interval depends on the
operating conditions, environment, atmosphere, and temperature. The greasing interval will therefore
require adjustment according to the respective case.

Simple installation in opposed positionInstalling two LM Guides opposing to one another used topose a number of problems: e.g., it is time-consuming anddifficult to attain the required accuracy and to adjustclearance.In the HSR-M1YR, however, tapped holes provided in theflange of the LM block to aid the mounting of a table hassimplified assembly and construction. This contributes tosubstantial man-hour reduction and improved precision.
Low profileSideways installation reduces the mounting height or thespacing between the base and table when the LM Guide isinstalled. This style of installation is also useful when there isa need for a wide guide to obtain greater table rigidity.
Higher rigidity achieved against lateral loadHSR-M1YR is installed sideways. This means that theapplied load is exerted on the center line of the train of balls,as shown below. Since the load does not act as a moment, ahigher rigidity is obtained.

LM Rail Standard and Maximum Lengths
The LM rail standard and maximum lengths of the High-Temperature LM Guide are as shown in Tables 7 through 9. If themaximum length for your application is not within the range found in the tables, we can produce special LM rails intended forconnected use.For dimension G, if you specify a special length, we recommend the values listed in the above tables. A longer dimension Gtends to reduce the stability of the rail at the rail ends after installation, possibly reducing accuracy.For connected use, we produce LM rails with no level difference at the joints. Accordingly, when placing an order, pleasespecify the overall length.

Notes: • These seal resistance values are measurements at normal temperature.• The data for type HSR-M1 apply to type HSR-M1YR as well.

Precautions on Use
Handling• Do not drop the product or subject it to impact, as doing so may damage it. Exercise due care in handling the
product.• Unauthorized disassembling of the product can result in the entry of foreign matter and reduce precision.
Therefore, disassembly should not be performed unless absolutely necessary. • Tilting an LM rail can dislocate the LM block, possibly causing it to fall. Exercise due care to prevent the LM block
detaching.• The product is moisture proof packed after sufficiently degreased and washed. Please open the package just
before use.• After unpacking the LM Guide, store it in a clean, dry container with a desiccant. Do not apply corrosion-preventive
oil, volatile corrosion-preventive paper (agent), or the like.• Handle the product in a clean place, wearing vinyl gloves.
Operating temperature range• Although the maximum permissible temperature for the product is 150°C, consider an appropriate temperature and
a hardness coefficient (the latter = 1) when calculating nominal service life and static safety factor. For details, seethis catalog and the General Catalog.
