30211 J2/Q SKF 55x100x22,75 Tapered Roller Bearing

Industrial Applications

30211 J2/Q SKF 55x100x22,75 tapered roller bearing is a single row rolling bearing designed for systems exposed to combined radial and axial loads. This model strengthens the SKF tapered roller bearings category in the 55 mm bore segment, widely used in gear units, hubs and industrial drive assemblies.

The 55x100x22,75 mm configuration is commonly applied in:

• Industrial gearboxes

• Drive axles

• Wheel hubs of industrial machinery

• Transmission shafts

• Agricultural and construction equipment

In these applications, the ability to adjust axial clearance and maintain load stability under dynamic conditions is essential for long term reliability.

Construction and Design

SKF 30211 J2/Q features tapered raceways on both the inner and outer rings, combined with tapered rollers. The geometry allows efficient transmission of axial loads in one direction while simultaneously supporting high radial loads.

The J2 designation indicates a pressed steel cage, ensuring reliable roller guidance and mechanical strength. The Q specification refers to optimized internal geometry and improved raceway surface finish, contributing to better load distribution and extended service life.

The bearing has a separable design, allowing the inner ring with roller and cage assembly to be mounted independently from the outer ring. This simplifies installation and enables precise adjustment of preload or axial clearance during assembly.
