Reliable alignment compensation with Skf

Practical benefits

Automatic misalignment compensation: The double-row self-aligning design allows you to easily compensate for shaft deflections and angular misalignment during operation.
Simple tapered mounting: The tapered bore enables you to quickly and securely mount the bearing onto shafts using adapter sleeves.
Enhanced C3 clearance: With internal C3 radial clearance and a lightweight polymer cage, you maintain smooth rotation under thermal expansion.

In a nutshell

The right choise for

With the Skf 2307 EKTN9/C3 double-row self-aligning ball bearing, you easily accommodate shaft deflections and angular misalignment without generating excess friction. Featuring dimensions of 35X80X31 mm, this open bearing is engineered with a 1:12 tapered bore for fast and secure mounting on shafts using an adapter sleeve. The increased C3 radial internal clearance combined with a lightweight glass-fibre reinforced polyamide cage ensures smooth rotation under thermal expansion and high operating speeds in conveyor systems, fans, and industrial machinery. This design protects your rotating equipment from premature wear and keeps your production running reliably.

Product description

Self-aligning ball bearings, with a tapered bore, 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, which can be caused, for example, by shaft deflection. The tapered bore facilitates ease of mounting via adapter sleeves or withdrawal sleeves.
