Roller assembly and method of making

Abstract

A roller may have a roller cylinder having two ends and an axle assembly in at least one end of the roller cylinder. The axle assembly has an axle stub extending out from the roller cylinder and rotatably mounted therein by two spaced-apart bearings. In another aspect, an axle cartridge for a roller includes a sleeve having a length and having two ends and two bearings mounted in the sleeve, spaced-apart from each other. An axle stub is mounted in the bearings for rotation relative to the sleeve, the axle stub being configured to protrude from the sleeve. A roller may be manufactured by mounting an axle cartridge as described herein in each end of a roller cylinder.
