What are the dimensions of this SKF angular contact ball bearing?

This bearing has an inside diameter of 55 mm, an outside diameter of 100 mm, and a width of 33.3 mm.

What loads can the SKF 3211 A-2RS1/MT33 support?

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

What sealing does this bearing have?

The 2RS1 designation indicates contact rubber seals on both sides to keep out dust and moisture.

Does this bearing need lubrication before installation?

No, the MT33 suffix means it comes pre-greased with lithium grease from the factory.

What internal clearance does this model feature?

It features standard normal internal clearance (CN).

Dependable performance with Skf

Practical benefits

High combined load support: The double-row layout with a 30° contact angle enables you to support high radial and bidirectional axial loads effortlessly.
Effective dual rubber sealing: Integrated seals on both sides protect your bearing against external contaminants while preventing lubricant loss during heavy operation.
Space saving rigid design: You achieve a stiff and stable bearing arrangement that requires significantly less axial space than two single-row bearings.

In a nutshell

The right choise for

With the Skf 3211 A-2RS1/MT33 double-row angular contact ball bearing, you reliably handle heavy radial and bidirectional axial loads in demanding applications such as pumps, compressors, and gearboxes. Featuring a 30° contact angle and compact dimensions of 55 x 100 x 33.3 mm, it delivers a stiff and stable arrangement that saves valuable axial space compared to two paired single-row bearings. The dual rubber contact seals (2RS1) keep dust and moisture out while retaining the factory-filled grease (MT33) for maintenance-free operation. This ensures your rotating equipment runs smoothly, accurately, and without unnecessary downtime.

Key features according to our expert

Inner diameter: 55 mm
Width: 33,3 mm
Number of rows: 2
Axial clearance: CN (Normal)
Sealing (bearing): Sealed on both sides
Material (bearing seal): Rubber
Material (cage): Brass (sheet)

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
