Roller bearings are the standard bearing in most
caster applications. 1-1/2 and 2 inch width wheels
feature a cage separating hardened steel rollers and
a hardened steel split outer race. These bearings
must be used on a hardened bushing or shaft. Maxi-
mum temperature range is 350°F. All Casters and
wheels are rated up to 2.5 mph operation per the In-
stitute of Caster & Wheel Manufacturers Guidelines.

These are roller bearings as described above except
they have metal cages holding the precision ground
rollers. The outer race is a one-piece construction,
giving added rigidity to the wheel bore. These bear-
ings must be used on a hardened bushing or shaft.
Maximum temperature range is 400°F.

The tapered roller is the most effective bearing for
heavy or towed loads. The taper allows for some
thrust loading, while the heat-treated inner and outer
race allow for maximum load capacity. Maximum
temperature range is 400°F.

Excellent for wash-down or steam cleaning applica-
tions. Bronze bearings are designed for tempera-
tures up to 525°F.
23
These bearings are made of oil-impregnated
sintered iron. Completely self-lubricating, these are
ideal for situations where rolling force is less critical
and accessibility for lubrication is difficult. Maximum
temperature range is 450°F.
27
Shielded ball bearings are often referred to as
“industrial grade” bearings. Pressed into the hub of
lower capacity wheels, these low cost bearings de-
crease the effort required to move a load. Maximum
temperature range is 250°F.
28
Completely sealed, these precision ground ball bear-
ings are held in a metal spacer ring between two
hardened raceways. This bearing never needs to be
lubricated, and with the lowest rolling resistance of
all bearings it provides the most ergonomic situation
available. Maximum temperature range is 250°F.
29
These sealed precision ball bearings include an
integral spanner which eliminates need for separate
spanner. Maximum temperature range is 250°F.

In this option, no bearing material is used. The
wheel runs directly on the axle or spanner bushing.
This is the least expensive bearing option, but also
results in a higher rolling resistance.

A DuPont
TM
engineered material, Delrin is designed
for use in situations in which a self-lubricating mate-
rial is optimal and corrosion cannot be tolerated.
Ideal for wash-down or steam-cleaning applications
as well as total immersion. Maximum temperature
range is 160°F.
This is a one-piece version of the Delrin
bearing listed above. Good for use where thrust
washers are needed or to add rigidity to a soft
wheel which might cause the two piece bearing to
be ejected from the bore of the wheel. Maximum
temperature range is 160°F.
A precision type bearing where the machined
outer race and inner race are held together by the
bearings. This option offers easy rolling and quiet
operation for light to medium duty loads. This bear-
ing must be factory installed in the wheel. Designed
for temperatures up to 160°F.
