What are the dimensions of this SKF ball bearing?

The bearing features a 45 mm bore diameter, a 100 mm outside diameter, and a width of 36 mm.

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

The double-row design accommodates angular misalignment and shaft deflections without increasing friction.

How do you mount a bearing with a tapered bore?

The tapered bore (indicated by K) is designed to be mounted on a shaft using a matching adapter sleeve.

What material is the bearing cage made of?

The cage for this TN9 version is made of glass-fibre reinforced polyamide (polymer/plastic).

Is this bearing sealed?

No, this is an open-type bearing without built-in seals and requires external lubrication.

Smooth operation with Skf

Practical benefits

Accommodates severe shaft deflection: The double-row self-aligning design lets you compensate for static and dynamic misalignments without added stress.
Simple and secure mounting: With its tapered bore, you can fit the bearing quickly and securely onto shafts using adapter sleeves.
Low friction at speed: The engineered polymer cage minimizes heat and friction, enabling you to maintain high rotational speeds smoothly.

In a nutshell

The right choise for

Keep your industrial machinery and drive systems running smoothly with the Skf 2309 EKTN9 double-row self-aligning ball bearing. Its double-row design effortlessly compensates for shaft deflections and angular misalignment without increasing friction or housing stress. Thanks to the tapered bore, you can mount the bearing quickly and securely onto smooth or stepped shafts using an adapter sleeve. Featuring dimensions of 45X100X36 mm and a lightweight polymer cage, this open bearing minimizes heat generation and vibration at high rotational speeds, protecting your conveyor drives and mechanical setups against premature failure.

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.
