RPMBRND - RPMBRND ZEF6307

New design tapered adapter mount spherical roller bearing units provide versatile arrangements for supporting shafts that carry substantial radial or a combination of radial and thrust loads

Incorporates an integral lock nut, sleeve and inner race along with Optical Strain Sensing (OSS) technology and a Positive Locking System (PLS) that visually indicates when the bearing is tightened to the shaft correctly

These features not only yield the most secure shaft mounting, running accuracy and ability to accommodate undersize shafting, but guarantee the correct installation every time and make removal a snap

Offers higher dynamic load ratings than the previous design, runs cooler and runs quieter yielding a bearing that lasts longer in the application

Dynamic and static misalignment capability has been increased to ±2.0°

Rollers are aligned by the retainers and the inner race, so despite misalignment, the roller load is always equally distributed across the surface; prevents high edge load stresses on the rollers and therefore it is not necessary to derate the bearing for misalignment conditions within the ±2.0°

Easy to mount and dismount, sealed, prelubricated and does not require adjustment during mounting

Additional key features include: Choice of various seal types based upon application; all seals assure protection with up to ±2.0° of misalignment in all directions, provide operation on hardened and ground inner ring extensions and can be removed without disassembly of the bearing; field adjustable bearing clearances based upon application need; fully self-aligning spherical roller bearing that accommodates for operational misalignment or misalignment due to installation; case-carburized inner races provide a hard, fatigue-resistant surface and a tough, crack-resistant ductile core
