Abstract
A conveyor roller includes at least one axle cartridge and is mounted at opposite sidewalls of a conveyor. The axle cartridge includes a bearing assembly at an outer end and an inner support at an inner end. The bearing assembly provides rotational support of a roller portion about the axle portion, while the inner support is spaced from an inner end of the axle portion during normal use of the roller. The inner support may provide contact support at the inner axle portion in response to loading induced deflection of the roller, whereby the inner support limits flexing or bending of the roller portion and may limit binding of the bearing assembly during such loading conditions. The axle portion may include one or more guide members arranged along a generally tapered or conical-shaped axle end for guiding the axle portion into a correspondingly formed opening in the conveyor sidewall.
