Rolamite

Rolamite mechanical roller-band device that functions as an almost frictionless suspension system for rollers it consists of a flexible metal band formed in an S-shaped loop In the Figure rollers A and B are suspended within the loops of the flexible metallic band C fastened at D and E to the parallel guide rails F and G The sum of the roller diameters and twice the band thickness is

Rotary Kiln Maintenance Procedures

The roller will move axially until the thrust mechanism inside one of the bearings stops the lateral motion If the degree of roller misalignment is high the pressure on this thrust mechanism (either a bearing end cap or a thrust collar) becomes high and increased bearing temperature results

Rolling

A rolling-element bearing also known as a rolling bearing is a bearing which carries a load by placing rolling elements (such as balls or rollers) between two bearing rings called races The relative motion of the races causes the rolling elements to roll with very little rolling resistance and with little sliding One of the earliest and best-known rolling-element bearings are sets of logs
