SKF 33211 Tapered Roller Bearing 55x100x35 mm

Design and Construction

SKF 33211 tapered roller bearing 55x100x35 mm is a single row bearing engineered for shaft systems requiring increased rigidity and high load capacity. Within the SKF tapered roller bearings category, model 33211 belongs to the 33200 series, designed for more demanding industrial applications compared to lighter 33100 variants.

The bearing incorporates tapered rollers operating between precisely machined tapered raceways of the inner and outer rings. This geometry provides line contact, enabling efficient transmission of radial loads together with significant axial loads in one direction.

SKF 33211 features a separable design. The inner ring assembly with cage and tapered rollers can be mounted independently from the outer ring, simplifying installation and allowing accurate axial clearance or preload adjustment in paired configurations.

Main Description

SKF 33211 55x100x35 mm is a single row tapered roller bearing designed to support high radial loads and substantial axial loads in one direction in industrial transmission systems.

As part of the SKF tapered roller bearings cluster, model 33211 serves as a robust solution for medium diameter shafts operating under demanding load conditions. The tapered roller geometry ensures optimized stress distribution along the contact lines, reducing localized fatigue and extending service life.

The 55x100x35 mm configuration is frequently selected for industrial gearboxes where axial loads arise from helical gear operation. SKF 33211 can operate as a single bearing for one direction axial load support or be mounted in back to back or face to face arrangements to accommodate axial loads in both directions after proper preload or clearance adjustment.

In heavy duty industrial environments, where vibration and load fluctuations are common, the SKF 33211 tapered roller bearing provides predictable mechanical behavior and reliable shaft guidance. Maintenance teams benefit from the separable construction, enabling precise installation and controlled axial clearance setting during assembly.

SKF 33211 tapered roller bearing 55 mm bore is therefore a dependable choice for applications requiring high load capacity, rigidity and long term operational stability.
