Cylindrical roller thrust bearings

‌SKF Cylindrical Roller Thrust Bearings‌ are bearings specially designed to withstand heavy axial loads and impact loads. They cannot withstand any radial loads, have high axial rigidity and small axial space requirements‌

Structural Features

SKF Cylindrical Roller Thrust Bearings consist of the following main parts:

‌Shaft washers‌ and seat washers: These washers provide the support surface of the bearing.

‌Cylindrical rollers‌: These rollers usually have a convex surface to ensure uniform pressure distribution between the rollers and the raceway surface.

‌Cages‌: Used to keep the rollers in place and prevent them from falling off or colliding with each other.

Application Scenarios

This type of bearing is suitable for occasions where heavy axial loads need to be borne, such as:

‌Heavy machinery‌: In heavy equipment that requires high axial load capacity, such as cranes, excavators, etc.

‌Industrial equipment‌: In industrial equipment that requires stable support and low-speed operation, such as conveyor belts, conveyors, etc.

Performance characteristics

‌High load capacity‌: Able to withstand large axial loads, suitable for heavy-duty applications.

‌High rigidity‌: With high axial rigidity, suitable for occasions requiring stable support.

‌Low friction‌: The design reduces friction and extends the service life of the bearing.

‌Suitable for low-speed applications‌: Although designed for low-speed applications, it performs well at low speeds.

SKF Cylindrical Roller Thrust Bearings are high-capacity, single-direction bearings engineered to withstand heavy axial loads while maintaining precision and durability. Featuring cylindrical rollers arranged perpendicular to the bearing axis, these bearings excel in applications requiring rigid axial support, minimal friction, and reliable performance under extreme stress.

Key Features & Benefits of ‌SKF Cylindrical Roller Thrust Bearings

Exceptional Axial Load Capacity

Designed to handle unidirectional axial loads efficiently, making them ideal for applications like vertical shafts, gearboxes, and heavy machinery.

Low Friction & High Rigidity

Optimized roller geometry and precision-ground raceways ensure smooth operation, reduced heat generation, and resistance to deformation under load.

Robust Construction

Hardened steel rollers and raceways provide superior wear resistance, even in high-speed or high-shock environments.

Separable Design

Components (shaft washer, housing washer, roller/cage assembly) can be mounted independently, simplifying installation and maintenance.

Alignment Tolerance

Accommodates minor misalignment between shaft and housing, reducing stress and prolonging service life.

Customizable Options

Available with various cage materials (steel, brass, or polymer) and lubrication solutions to suit specific operating conditions (high temperatures, corrosive environments)

Why Choose SKF Cylindrical Roller Thrust Bearings?

Performance Under Pressure: Engineered for reliability in the most demanding axial load scenarios.

Reduced Downtime: Easy assembly and disassembly minimize maintenance interruptions.

Long Service Life: Advanced materials and precision manufacturing reduce wear and extend operational lifespan.
