Assembling the roller we insert the machined shaft through the bore of the pipe fit one end cover at each end which have bearings, seals and grease protection fitted.
We then hydraulically drive the end covers into the pipe bore and as the machining of the outside diameter of the end cover is size for size with the bore of the pipe the end cover actually makes the pipe perfectly circular. The pipe is then crimped by a cold process into the groove already machined on the outside of the end cover. This seals the roller and prevents outside contamination. This is a unique process to Abbey Rollers and eliminates welding on of stampings and any distortion that results from heat.
Because the castings are machined in one machine setting they are perfectly true. The bearings are mounted on a machined shaft and the pipe is corrected by the tight fitting end covers. Therefore, the roller is running true off the spindle and the quality of the bearing, a 2RS C3 deep groove bearing is protected inside the roller.
