Sturdy load handling by Skf

Practical benefits

Dual metal shield protection: You shield internal components against dust and contaminants with pressed sheet steel shields on both sides.
Combined dual direction support: You accommodate heavy radial forces as well as axial loads in both directions with ease.
Smooth polyamide cage: The glass fibre reinforced polymer cage ensures reduced friction and smooth, quiet rotational performance.

In a nutshell

The right choise for

With the Skf 3305 A-2ZTN9/MT33 double row angular contact ball bearing, you ensure dependable performance and rigid support within limited axial space. Featuring a 30° contact angle, it accommodates heavy radial loads alongside simultaneous bidirectional axial forces, making it an ideal choice for electric motors, pumps, and gearboxes. The dual metal 2Z shields protect the pre-lubricated MT33 interior against dust and contaminants, eliminating the need for routine maintenance. Meanwhile, the lightweight glass-fibre reinforced polyamide TN9 cage minimizes friction and ensures quiet, smooth rotation at demanding speeds.

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): Metal
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
