A roller assembly for use, for example, in agricultural machines where the roller assembly has an exterior surface portion adapted to contact a conveyor element supporting the agricultural products and a bearing sub-assembly positioned about an axle in the center of the roller assembly. The bearing sub-assembly has at least one bearing, at least one sealing element having an elastomeric sealing portion positioned outboard of the bearing and at least one standoff also positioned outboard of the bearing. There may be a plug in place of one of the sealing elements, the plug being elastomeric and configured to make a compression fit with the hub.

Agricultural roller

A roller assembly for use, for example, in agricultural machines where the roller assembly has an exterior surface portion adapted to contact a conveyor element supporting the agricultural products and a bearing sub-assembly positioned about an axle in the center of the roller assembly. The bearing sub-assembly has at least one bearing, at least one sealing element having an elastomeric sealing portion positioned outboard of the bearing and at least one standoff also positioned outboard of the bearing. The standoffs have grooves in their outer dimension adapted to receive the elastomeric sealing portion. The diameter of the standoffs are about the same as the diameter of the elastomeric sealing portion. The horizontal length of the standoffs may also be chosen so as to offset the exterior surface portion of the assembly a predetermined distance with respect to the conveyor element.
