Abstract
A cartridge bearing assembly for a roller conveyor system includes a housing having a first end, a second end opposing the first end, an inner surface, and an outer surface. A pair of bearings is spaced from each other and disposed in the housing. An shaft is received by the pair of bearings. The shaft is formed from a plastic material. A spring is disposed about a first portion of the shaft intermediate the pair of bearings. The spring biases the shaft outwardly from the first end of the housing.

A cartridge bearing assembly for a roller conveyor system comprising:
- a housing having a first end configured for insertion into a roller, a second end opposing the first end, an inner surface, and an outer surface;
- a pair of bearings disposed in the housing and spaced from each other;
- a shaft received by the pair of bearings each of the pair of bearings having substantially equal diameters;
- and
- a spring disposed about a first portion of the shaft intermediate the pair of bearings, the spring biasing the shaft axially outwardly from the second end of the housing, wherein a plurality of engagement members is formed on an outer surface of the housing configured to engage a torque transmitter, wherein the engagement members are a plurality of grooves concentrically formed on the outer surface of the housing, wherein a flange divides the housing into a roller engagement portion and a torque transmitter engagement portion, and wherein the torque transmitter engagement portion includes the engagement members.
A cartridge bearing assembly for a roller conveyor system comprising:
- a housing having a first end configured for insertion into a roller, a second end opposing the first end, an inner surface, and an outer surface;
- a pair of bearings disposed in the housing and spaced from each other, each of the pair of bearings having substantially equal outer diameters;
- a shaft received by the pair of bearings;
- and
- a spring disposed about a first portion of the shaft intermediate the pair of bearings, the spring biasing the shaft axially outwardly from the second end of the housing, wherein the shaft is divided into a spring portion having a substantially circular cross-sectional shape and a frame engagement portion having a substantially hexagonal cross-sectional shape, and wherein the frame engagement portion has a width across flats of the hexagonal cross-sectional shape and a width across corners of the hexagonal cross-sectional shape substantially equal to or proximate a diameter of the spring portion.
