Hardware & Maintenance
Choosing a Caster
When replacing casters, try to match the new set as closely as possible to the originals. Upgrading a set of casters to a heavier duty type is recommended if
casters are prone to excessive wear.
When adding a set of casters, consider the weight and size of the equipment as well as the floor conditions. A heavy piece of equipment should have large
wheels to hold the weight and provide easy rolling. Floors that are rough can cause rubber caster wheels to wear quickly. Floors that are exposed to grease, oil,
or heavy detergents can also cause deterioration. In both cases, a caster with a polyurethane wheel will last longer than a caster that has a rubber wheel.
More information on selecting casters is provided below.
Caster Types

Swivel Stem Casters: The stem of these
casters fits inside of a leg. The stem is tightened to
expand the rubber sleeve and “lock” the caster into
the leg.
Plate Mount Casters: These casters usually
are used on equipment. The mounting holes in the
plate are commonly elongated for easier mounting
and alignment.
• Casters for 1" tubing are generally used on
freestanding shelving and carts
• Casters for 1 5 ⁄ 8 " tubing are generally used on
work tables and equipment stands
Threaded Stem Casters: These casters are
installed on equipment with a threaded hole, or
where a caster can be secured with a nut. They are
also ideal for replacing stud mount (threaded) legs
on a piece of equipment.

wheel types
Black and Gray
Rubber Wheels
Polyurethane Wheels
Polyolefin Wheels
These wheels are lightweight and high capacity.
They are resistant to water, oils, grease, gasoline,
and most commonly used chemicals. They are
also non-marking and non-conducive. Can handle
extreme shock loads.

These wheels are made with a TPR tread material
which is bonded to a polyolefin black core.
This construction offers superior performance,
silent operation, and resistance to all common
chemicals. The medium-duty wheels are supplied
with Delrin ® acetyl resin bearings, and the
standard-duty wheels have plain bearings.

These wheels are made with gray, non-marking
polyurethane tread material which is mechanically
locked to a gray polyolefin core. This construction
makes these wheels virtually indestructible and
shock resistant to sudden impacts. In addition to
rolling ease and quiet operation, these wheels
are resistant to water, acids, oil, and common
chemicals. The medium-duty wheels are supplied
with precision ball bearings, and the standard-duty
wheels have Delrin ® acetyl resin bearings.

Understanding Specifications
Institutional Grade: This is the highest grade
of caster available for the foodservice industry.
Equipment
Load
Height
Load Height: This is the distance a caster raises
a piece of equipment off the floor or the overall
height of the caster when mounted. It is important
when replacing casters because the new casters
may cause the equipment to sit higher or lower if
the load height is different from the original set.
How to Measure Tubing and Pipe
Tubing
• Tubing has a thinner wall thickness than pipe
• Tubing is measured from the outside diameter
• Pipe is measured from the inside diameter
Pipe
• To determine pipe size, measure the male
(threaded) end of the pipe:
I f OD is 1 1 ⁄ 4 " and under, subtract 1 ⁄ 4 ".
I f OD is 1 5 ⁄ 8 " and over, subtract 3 ⁄ 8 ".
Load Capacity: This is the total weight a set
of 4 casters can carry while the equipment is
in motion.
