What are the dimensions of this SKF bearing?

The bearing has a 20 mm bore diameter, a 47 mm outside diameter, and a width of 14 mm.

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

With two rows of balls and a sphered outer raceway, it easily accommodates angular misalignment and shaft deflection.

What cage material does the TN9 suffix designate?

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

Does this ball bearing have seals?

No, this is an open bearing without seals, intended for applications with external lubrication.

What type of bore does the 1204 ETN9 have?

It features a standard cylindrical bore designed to fit directly onto a 20 mm cylindrical shaft.

Reliable alignment under shaft deflection

Practical benefits

Automatic compensation for angular misalignment: You prevent mechanical stress as the two rows of balls adapt smoothly to shaft deflections and mounting inaccuracies.
Low friction at high speeds: With the lightweight polyamide cage, you experience reduced heat build-up and exceptionally smooth, quiet running performance.
Direct fit on cylindrical shafts: You install this bearing quickly on standard 20 mm shafts, ensuring a secure and straightforward mechanical fit.

In a nutshell

The right choise for

With the Skf 1204 ETN9 double-row self-aligning ball bearing, you prevent mechanical stress and premature failure caused by shaft deflection or mounting misalignment. Its two rows of balls and sphered outer raceway adapt smoothly to angular deviations, ensuring consistent, reliable rotation. Thanks to the lightweight polyamide cage, you benefit from low friction, reduced heat build-up, and quiet operation at high speeds. Designed with a 20 mm cylindrical bore, a 47 mm outside diameter, and a 14 mm width, this open bearing mounts quickly and accurately onto standard cylindrical shafts in industrial machinery, conveyor systems, and agricultural equipment with external lubrication setups.

Product description

Self-aligning ball bearings 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.

Accommodate static and dynamic misalignment
Excellent high-speed performance
Excellent light load performance
Low friction
