Heavy load reliability with Skf
- High radial load capacity: You handle heavy radial loads effortlessly thanks to the robust double-row spherical roller design.
- Effective self-aligning capability: You accommodate shaft deflections and angular misalignments with virtually no increase in friction or operating temperature.
- Convenient relubrication features: The integrated lubrication groove and holes allow you to service the bearing quickly and maximize operating life.
With the Skf 21311 e double-row spherical roller bearing, you keep heavy industrial machinery running reliably and efficiently. Designed with a 55 mm cylindrical bore, a 120 mm outside diameter, and a width of 29 mm, this bearing effortlessly handles heavy radial loads combined with axial forces in both directions. Its self-aligning design automatically accommodates shaft deflections and angular misalignment without increasing friction or operating temperatures. Thanks to the integrated relubrication features on the outer ring, you can perform routine maintenance quickly, minimizing downtime and significantly extending the service life of gearboxes, conveyors, and drivetrains.
Product description
Spherical roller bearings can accommodate heavy loads in both directions. They are self-aligning and accommodate misalignment and shaft deflections, with virtually no increase in friction or temperature. The design includes features to facilitate relubrication. The bearings can be used in a modular system, including housings, sleeves and nuts.
