What are the dimensions of this SKF bearing?

The bearing has a 25 mm inside diameter, a 62 mm outside diameter, and a width of 25.4 mm.

What types of loads can this bearing accommodate?

Due to its double-row design and 30° contact angle, it accommodates radial loads and axial loads in both directions simultaneously.

What does the 2RS1 designation mean?

It indicates that the bearing features contact rubber seals on both sides to protect against dust and moisture.

What material is the cage made from?

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

Does this bearing require lubrication before installation?

No, it is factory pre-greased with MT33 grease and is maintenance-free thanks to its dual-sided seals.

Reliable support for combined loads

Practical benefits

High combined load capacity: You support radial and axial loads in both directions efficiently thanks to the double row construction.
Reliable dual lip seals: Rubber contact seals safeguard your Skf bearing against contaminants while preventing internal lubricant loss during operation.
Smooth polyamide cage: The polymer cage reduces internal friction at high speeds, providing you with smooth and quiet running performance.

In a nutshell

The right choise for

With the Skf 3305 A-2RS1TN9/MT33 double-row angular contact ball bearing, you ensure reliable stability and smooth rotation in drivetrains, gearboxes, and industrial pumps. Thanks to its double-row design and 30° contact angle, you efficiently accommodate high radial loads and bidirectional axial forces simultaneously while saving valuable axial mounting space. The dual-sided rubber contact seals reliably protect against dust and moisture while keeping lubricant locked inside. Combined with a low-friction plastic cage, this sealed bearing delivers quiet, dependable running performance with no need for relubrication.

Key features according to our expert

Inner diameter: 25 mm
Width: 25,4 mm
Number of rows: 2
Axial clearance: CN (Normal)
Sealing (bearing): Sealed on both sides
Material (bearing seal): Rubber
Material (cage): Plastic
Outer diameter: 62 mm

Product description

Double row angular contact ball bearings, with seals or shields, correspond to a pair of single row angular contact ball bearings in a back-to-back arrangement, while requiring less axial space. Depending on the sealing execution, they can operate at high speeds and are more suitable than deep groove ball bearings for supporting large axial forces in both directions.

High-speed capability
Accommodate relatively high radial loads, high axial loads in both directions and tilting moments
Suitable where a stiff bearing arrangement is required
Require less axial space than equivalent pair of single row angular contact ball bearings
Integral sealing prolongs bearing service life
