Smooth operation under shaft deflection

Practical benefits

Automatic compensation for misalignment: You compensate for angular misalignment and shaft deflections easily thanks to the dual-row spherical raceway design.
Easy Skf 1211 EKTN9 installation: The tapered bore allows you to mount the bearing securely using standard adapter or withdrawal sleeves.
Low-friction polyamide cage performance: The durable polymer cage minimizes heat generation so you achieve smooth running even at high rotational speeds.

In a nutshell

The right choise for

With the Skf 1211 EKTN9 double-row self-aligning ball bearing, you keep rotating shafts running smoothly and reliably, even when subjected to shaft deflection or misalignment under load. Its dual-row design automatically compensates for angular errors without increasing friction or internal stress. Thanks to the tapered bore, you can mount and dismount the bearing securely on smooth or stepped shafts using an adapter sleeve. The glass-fiber reinforced polyamide cage (TN9) minimizes heat generation and friction, ensuring quiet and efficient performance at high operating speeds in conveyor systems, industrial fans, and agricultural machinery.

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.
