SKF 33109 Tapered Roller Bearing 45x80x26

Design and Construction

SKF 33109 tapered roller bearing 45x80x26 is engineered for compact transmission systems where combined radial and axial loads must be reliably supported. Within the SKF tapered roller bearings category, the 33109 model represents a medium size solution optimized for adjustable shaft arrangements and controlled axial positioning.

The bearing features a single row of tapered rollers operating between tapered raceways of the inner and outer rings. The geometry ensures that the load lines converge at a common point on the bearing axis, enabling efficient transmission of axial loads in one direction while maintaining strong radial load capacity.

SKF 33109 has a separable design. The inner ring assembly with rollers and cage can be mounted independently from the outer ring, simplifying installation, inspection and preload adjustment in industrial drive systems.

Main Description

SKF 33109 45x80x26 is a single row tapered roller bearing designed to support radial loads and axial loads in one direction in gearbox and drive assemblies.

As part of the SKF tapered roller bearings cluster, model 33109 serves as a versatile component for medium diameter shafts requiring precise axial positioning and adjustable clearance. The tapered roller geometry ensures line contact between rollers and raceways, promoting efficient load distribution and reduced surface stress.

The 45x80x26 mm configuration is widely applied in industrial gear transmissions and mechanical drive systems where axial forces are generated by helical or bevel gears. SKF 33109 can be installed individually for single direction axial load support or in back to back or face to face arrangements to handle axial loads in both directions.

In industrial environments where reliability and serviceability are critical, the separable construction simplifies installation and maintenance. Maintenance teams benefit from the ability to adjust axial clearance or preload during assembly, ensuring optimal operating conditions.

SKF 33109 tapered roller bearing 45 mm bore is selected in applications requiring a compact yet robust solution that combines mechanical rigidity, load capacity and predictable long term performance.
