At Rite Idler, our design focus has always been the protection and proper lubrication of our bearings. What sets us apart? Our sealing system incorporates seven component parts. Four seals lie between the bearing and the roll end, and three seals lie between the bearing and the roll’s interior. We are the only company to do this! We do NOT use “sealed for life” bearings. We pressure inject the seals to fill the entire cavity with grease – resulting in 10-15 times the volume of grease.
