Smooth rotation during shaft deflection

Practical benefits

Automatic misalignment compensation: You accommodate dynamic and static angular errors easily thanks to the double-row self-aligning design.
Low friction high-speed performance: The lightweight polymer cage minimizes friction so you maintain efficient running even at elevated speeds.
Easy adapter sleeve mounting: With the tapered bore, you securely mount the Skf 1309 EKTN9 on standard transmission shafts.

In a nutshell

The right choise for

With the Skf 1309 EKTN9 double-row self-aligning ball bearing, you keep rotating machinery running smoothly even during shaft deflections or angular misalignment. Its double-row design effortlessly compensates for both static and dynamic alignment errors relative to the housing. The tapered bore ensures straightforward, secure mounting onto shafts using adapter sleeves. In addition, the glass-fibre reinforced polyamide cage minimizes friction to maintain stable operation at high speeds. Featuring open dimensions of 45X100X25 mm, this robust bearing delivers dependable performance for industrial blowers, conveyor rollers, and rotating drive systems.

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.
