Abstract: A bearing assembly having integral molded bearing surfaces. Each bearing surface is molded within its respective inner and outer race. The use of plastic injection molded parts enables high precision with low cost to achieve a reliably rotating caster wheel. The use of integral molded bearing surfaces within the respective races eliminates the problem of having to remove flash from the molding process or concern about indentations made by ejection pins if a separate bearing part were used. The use of a split spanner bushing with the openings of the inner race members permits the bearings to be more easily assembled as well provides greater strength and integrity to the bearing assembly once it is molded into a hub and wheel.

The bearing assembly can also be used with a molding process wheel to further reduce the cost of production.

Abstract: A brake for a caster having a caster wheel with a wheel hub axially mounted to a fork. The brake includes a leg adapted to pivotally engage the fork of the caster. When the brake is mounted to the caster, the leg wedges between the fork and the wheel hub to frictionally arrest the motion of the caster wheel.

Abstract: A molded wheel and bearing assembly includes two bearings in a molded housing forming a bearing assembly. The bearing assembly is molded into the hub of a caster wheel. The caster wheel is made by molding a hub around the bearing assembly, then molding a tread around the hub. No assembly of individual elements into the wheel is necessary.
