13 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. To understand how bearing codes are represented in part numbers, please visit page 18 . 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. 01, 05, 07 BEARING CODE: BEARING CODE: BEARING CODE: BEARING CODE: BEARING CODE: BEARING CODE: BEARING CODE: BEARING CODE: BEARING CODE: BEARING CODE: BEARING CODE: BEARING CODE: 02 09 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. 22 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. 31 41 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. 51 52 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.
