What are the dimensions of this SKF ball bearing?

The bearing has a 45 mm bore diameter, an 85 mm outside diameter, and a width of 19 mm.

What is the purpose of the tapered bore?

The tapered bore (indicated by K) allows straightforward mounting onto shafts, typically using an adapter sleeve.

What is the main benefit of a self-aligning ball bearing?

It compensates for angular misalignments and shaft deflections while maintaining low friction and smooth running.

What material is used for the cage?

The TN9 designation indicates a cage made from glass-fibre reinforced polyamide (composite plastic).

Is this bearing sealed?

No, this is an open-type bearing without built-in seals.

Reliable rotation with shaft misalignment

Practical benefits

Automatic compensation for misalignment: The two rows of balls accommodate shaft deflections effortlessly, ensuring your machinery continues running smoothly and reliably.
Fast tapered bore mounting: The tapered bore allows you to mount this Skf bearing quickly and securely onto an adapter sleeve.
Low friction and heat: The polyamide cage reduces friction during operation, helping you achieve high rotational speeds with minimal wear.

In a nutshell

The right choise for

Keep your rotating machinery running smoothly and reliably with the Skf 1209 EKTN9 double-row self-aligning ball bearing. Designed with two rows of balls, it automatically compensates for angular misalignments and shaft deflections, preventing premature bearing failure and excessive friction in industrial conveyors, blowers, and drive shafts. The tapered bore makes mounting straightforward and secure when paired with an adapter sleeve, especially on smooth shafts without shoulders. Equipped with a glass-fibre reinforced polyamide cage, it minimizes operational friction and heat generation at high rotational speeds. This durable, open bearing gives you the confidence to carry out effective maintenance and ensure dependable machine operation.

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.
