SKF SR Thrust Bearing
The SKF SR Thrust Bearing is a premium thrust bearing designed to handle high loads with efficiency and reliability. Available in diameters from 25mm to 50mm, these bearings are engineered with a conical clamping sleeve that is pressed directly onto the shaft’s outer diameter, ensuring secure mounting and stable load distribution. The bearing is partially filled with oil (about one-third of its capacity) to reduce friction and heat buildup. This type of bearing is commonly used in applications where high thrust loads are present, such as industrial machinery and ship drives. Larger sizes are available upon request.
Key Features:
- Conical clamping sleeve for secure mounting
- Oil-filled for reduced friction and longer lifespan
- Suitable for high thrust loads in industrial and marine applications
- Available in diameters from 25mm to 50mm
- Delivery available up to 100mm, larger sizes on request
