The IBO IKRL series are one side sealed tapered roller bearings lubricated with high-performance grease for life. Where they are installed in pairs in O-arrangement, the self-restraining bearings form a ready-to install both-sides sealed bearing with a defined axial clearance. The bearing absorbs a very high loading combination of radial and axial forces and tipping moments at moderate turning motion due to the support base arising from the O-arrangement of the specific contact angle.
