Smooth operation through misalignment

Practical benefits

Skf accommodates shaft deflection: The self-aligning design compensates for angular misalignment between shaft and housing, ensuring you maintain smooth, low-vibration performance.
Dual-sided contact seals: Integrated rubber seals keep lubricant securely inside while blocking external contaminants, reducing your maintenance needs over time.
Low-friction polymer cage: The lightweight polyamide cage reduces internal friction and operating temperatures, allowing you to achieve high rotational speeds reliably.

In a nutshell

The right choise for

With the Skf 2306 E-2RS1TN9 self-aligning ball bearing, you keep your machinery running smoothly and reliably, even when facing shaft deflection or angular misalignment. This double-row bearing measuring 30X72X27 mm compensates for alignment errors effortlessly without creating excess friction or wear. Dual-sided rubber contact seals (2RS1) retain the lubricant inside while effectively locking out dirt, dust, and moisture to extend service life. The lightweight polymer cage (TN9) reduces friction and operating temperatures for quiet performance at high speeds. It is the practical choice for overhauling and maintaining conveyor systems, pumps, fans, and agricultural machinery with a cylindrical shaft.

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
