Rigid performance under combined loads

Practical benefits

Double row load capacity: You support high radial loads alongside axial forces in both directions using the integrated double row layout.
Stiff angular contact design: The 30° contact angle provides superior rigidity and effortlessly accommodates tilting moments in tight spaces.
Dual rubber contact seals: Built-in 2RS1 rubber seals protect internal lubrication from contaminants and moisture to extend operational bearing life.

In a nutshell

The right choise for

With the Skf 3307 A-2RS1TN9/MT33, you achieve rigid and dependable operation under combined loading. Featuring a double row design and a 30° contact angle, this angular contact ball bearing effortlessly accommodates heavy radial forces alongside bidirectional axial loads in tight spaces. The lightweight glass-fibre reinforced polyamide cage reduces friction and noise, while the dual 2RS1 rubber contact seals keep out contaminants and moisture. Factory pre-lubricated with MT33 grease, it arrives ready for immediate installation on 35 mm shafts without the need for initial maintenance.

Key features according to our expert

Inner diameter: 35 mm
Width: 34,9 mm
Number of rows: 2
Axial clearance: CN (Normal)
Sealing (bearing): Sealed on both sides
Material (bearing seal): Rubber
Material (cage): Plastic
Outer diameter: 80 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
