Debunking Common Myths About Specifying Special Components
Debunking the mythsTodays engineers have more component specifying choices than ever. Standard or application-specific components? Both have advantages and disadvantages.This decision should be driven by the application.
Debunking the mythsDesign engineers should choose the ideal component for their design instead of what is in a catalog or online. Well explore the strengths and applications for both standard and special components. Well help engineers make the most educated decision when specifying.
Special vs. Standard Components
What is a standard component?Manufactured to an exact industry standard. Predictable in design. Governed by specific guidelines for tolerances and dimensions.Generally produced in mass quantities.No customization for specific applications.
When is a standard component used?In applications that dont require components to be modified or have unique considerations. When space is unrestricted.When engineers have the time and funds to design around the component or purchase additional materials to accommodate it.
Why choose standard components?Standard components have usually been the most common and accessible.They are often seen as the only viable option.Easily found in catalogs. Seem more cost- and time-effective.However: not necessarily true any longer.
What is a special component?A special component is precisely designed and built to fit a specific application.Special components have no limit or standards for size, shape or construction.
When is a special component used?When standard components dont fit the space, wont last within the application, etc.When engineers need to define a specific use.For new designs without predetermined limits.
Why choose special components?When engineers need more flexibility than a standard piece offers. To accommodate the exact needs of a specific application.When a standard component isnt working.To solve a problem that a standard component cant.
The Disadvantages of Standard Components
The disadvantages of standard componentsTodays designs require that components used are precise and fit the exact application needed.Engineers design around a standard component instead of getting the exact component they need.To make a standard component work often requires additional materials, time and cost to mount the piece properly.
The disadvantages of standard componentsMass produced and uniform components often limit engineers options.There are times when standard components work just fine. But when they wont, remember there are other affordable and timely options at your disposal: special components. But first, learn the truth about these special components.
Whats the Truth About Special Components?
The truth about special componentsSpecial components are often avoided because there are many misconceptions surrounding them.They have been viewed as too expensive, hard to get and impossible to replicate.Some manufacturers have been working to overcome these obstacles and give engineers the option to get the exact component they need.
3 Myths About Special Components
Myth #1: higher costMyth #1: Custom components are more expensive (even cost-prohibitive) than standard onesFALSEStandard components often require extra parts, increasing costs by 10-15%.Special components can be designed to withstand repetitive use and extra force, decreasing the frequency of needed replacement.
Additional engineering time to make standard components work can increase a project timeline and cost.Designs with special components will work better and more effectively over time, reducing life cycle costs.
Myth #2: longer production timeMyth #2: Custom components take much longer to produceDesigning around standard components already adds considerable time to the project.Special components will eliminate the time spent searching for, securing and applying parts to make a standard component fit.Equipment changes allow for smaller production runs, reducing the required manufacturing time.Careful ordering can make the production process just as fast as ordering standard components off the shelf.FALSE
Myth #3: parts are hard to getMyth #3: Spare or replacement parts for custom components arent readily available.Spare or replacement parts can often be produced in less time than it took to build the original part.This gives engineers the flexibility to order what they need, when they need it.Streamlined processes and equipment allow for a ready supply of additional parts for each specialized component designed and built.Some manufacturers dont even have a minimum for custom orders.FALSE
Whats the real story?Special components have become: more affordable.more convenient. quicker to secure.Manufacturers are overcoming roadblocks to help design engineers get the exact component they need for their application.
Making the Standard vs. Special Component Decision
Consider your options - 1What is the temperature environment the component will be operating in? Will the component be subject to any kind of wash down? Will there be any kind of abrasive materials in the area?How much linear force do you require out of the component?Do you have enough room for a standard component? Are you replacing an existing component that is failing? YES NOYES NOYES NOYES NO
Consider your options - 2Do you require the flexibility of adjusting the end of stroke position?Does your application require you to know where the piston is at times? What is the operating pressure?What is the operating media?YES NOYES NO
SummaryDesign engineers should choose special or standard components based on whats best for their design.Standard components are often mass-produced and may require design compromises.Special components can be cost effective and easily obtained and serviced with modern production techniques.

Todays engineers have more choices than ever when it comes to specifying the proper components for all types of applications.
There are advantages and disadvantages to choosing an application-specific component or a standard component.
This decision is mostly driven by the application.
*The goal of a design engineer should be to choose the ideal component for a design, and not to limit this decision by what is in a catalog or what is found online.
Therefore, today we will explore the strengths and appropriate applications for both standard and special components so that design engineers can make the most educated decision when specifying for their designs.
*What is a standard component?A component manufactured to an exact industry standard.
They are predictable in design.
Trade organizations such as NFPA, ISO and others have established specific guidelines governing the tolerances and dimensions of standard components.
Standard components are generally produced en mass more of a production driven model with no customization for specific applications.
*When is a standard component used?
Standard components are usable in a wide range of applications that dont require components to be modified or have unique considerations.
They are normally chosen when space is unrestricted.
Standard components cannot be manipulated or customized without additional cost, so engineers will design around this type of component or purchase additional materials to accommodate the piece.
Standard components are currently used roughly 90% of the time.
*Why do engineers choose standard components?
Standard components are historically the natural selection for design engineers because they have been the most common and accessible.
Standard components are often seen as the only option, as they appear in catalogs and have been the more cost effective and timely option in the past.
However, recent innovations have now made it possible to use special components when it would have been impossible or cost and time prohibitive before.
*What is a special component?
A special component is precisely designed and built to fit a specific application.
There is no limit or standard to the size, shape or construction of a special component.
*When is a special component used?
Special components lend themselves to designs in which standard components do not fit the space, do not last within the application, etc.
Special components also allow engineers to define how to use them and are great for new designs where the engineers only limit is his or her creativity.
They are currently used roughly 10% of the time.
*Why choose special components?
Design engineers use special components
