Superior thrust capacity with Skf

Practical benefits

High bidirectional axial support: You handle heavy axial forces in both directions smoothly thanks to the four-point contact geometry.
Space-saving compact construction: This design replaces double-row arrangements and requires significantly less axial mounting space in your machine.
Solid machined brass cage: The durable brass cage provides exceptional guidance and reliable operation under demanding high-speed conditions.

In a nutshell

The right choise for

With the Skf qj 309 ma four-point contact ball bearing, you ensure reliable performance in demanding industrial applications. Thanks to its 35° contact angle design, you handle high axial loads in both directions alongside small radial forces with ease. Measuring 45X100X25 mm, this compact bearing saves significant axial mounting space compared to traditional double-row setups, making it ideal for gearboxes, pumps, and compressors. The solid machined brass cage and normal internal axial clearance (CN) deliver superior guidance, stability, and dependable operation at high speeds, keeping your rotating machinery running smoothly.

Product description

Four-point contact ball bearings can accommodate high axial loads in both directions and small radial loads. They can operate at very high speeds and are more suitable than deep groove ball bearings for supporting large axial forces. The outer ring, with ball and cage assembly, can be mounted separately from the two inner ring halves.

High-speed capability
Accommodate high axial loads in both directions and small radial loads
Require considerably less axial space than double row angular contact ball bearings
