Reliable rotation under shaft misalignment

Practical benefits

Smooth self-aligning bearing operation: The spherical outer raceway allows you to easily compensate for angular misalignments and shaft deflections without friction.
Dual-sided contact seal protection: You keep lubricant securely inside while blocking dirt and moisture thanks to the durable rubber seals.
Reliable Skf cage performance: The reinforced polyamide cage ensures smooth rotation at high speeds and minimizes internal operating friction.

In a nutshell

The right choise for

Compensate smoothly for shaft deflections and angular misalignment with the Skf 2308 E-2RS1TN9 self-aligning ball bearing. Its double-row design and spherical outer raceway keep your rotating shafts running freely without added friction or mechanical stress. Dual-sided rubber contact seals securely retain factory grease while keeping out dust and moisture, significantly reducing your maintenance intervals. The lightweight, glass-fiber reinforced polyamide cage minimizes operating noise and vibration at high speeds. With standard cn internal radial clearance and dimensions of 40X90X33 mm on a cylindrical bore, this bearing provides reliable, long-lasting performance for industrial machinery, conveyor drives, and agricultural equipment.

Product description

Self-aligning ball bearings, with seals on both sides, have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are insensitive to angular misalignment of the shaft relative to the housing. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.

Accommodate static and dynamic misalignment
Excellent high-speed performance
Excellent light load performance
Low friction
Integral sealing results in reduced maintenance requirements and prolonged bearing service life
