Debunking Common Myths About
Specifying Special Components
Debunking the myths
• Today’s 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 myths
• Design engineers should choose the ideal
component for their design instead of what is
in a catalog or online.
• We’ll explore the strengths and applications for
both standard and special components.
• We’ll 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 don’t 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 don’t fit
the space, won’t 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 isn’t working.
• To solve a problem that a standard
component can’t.
The Disadvantages of
Standard Components
The disadvantages of standard components
• Today’s 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 components
• Mass produced and uniform components often limit
engineers’ options.
• There are times when standard components work
just fine. But when they won’t, remember there are
other affordable and timely options at your disposal:
special components.
But first, learn the truth about these special components.
What’s the Truth About
Special Components?
The truth about special components
• Special 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 cost
Myth #1:
Custom components
are more expensive
(even cost-prohibitive)
than standard
ones
Standard 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 time
Myth #2:
Custom components
take much longer to
produce
Designing 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.
Myth #3: parts are hard to get
Myth #3:
Spare or replacement
parts for custom
components aren’t
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
don’t even have a
minimum for custom
orders.
What’s 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 - 1
1. What is the temperature environment the component will
be operating in?
2. Will the component be subject to any kind of “wash down”?
3. Will there be any kind of abrasive materials in the area?
4. How much linear force do you require out of the
component?
5. Do you have enough room for a “standard” component?
6. Are you replacing an existing component that is failing?
YES NO
YES NO
YES NO
YES NO
Consider your options - 2
7. Do you require the flexibility of adjusting the end of stroke
position?
8. Does your application require you to know where the
piston is at times?
9. What is the operating pressure?
10. What is the operating media?
YES NO
YES NO
Summary
Summary
• Design engineers should choose special or standard
components based on what’s 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.
