SKF combined bearings refer to bearings that combine radial and axial load-bearing capacity, typically consisting of a radial needle roller bearing and a thrust bearing. This design is particularly suitable for applications that require simultaneous radial and axial loads, such as those with limited space, heavy axial loads, high rotational speeds, or poor lubrication conditions
Type and Design
SKF combined beads are mainly divided into the following three basic designs:
Needle roller/angular contact ball bearing: This design combines needle roller bearings and angular contact ball bearings, suitable for simultaneously bearing radial and axial loads
Needle roller/thrust ball bearings: Combining needle roller bearings and thrust ball bearings, suitable for applications that require high load-bearing capacity
Needle roller/cylindrical roller thrust bearing: Combining needle roller bearings and cylindrical roller thrust bearings, suitable for applications that require high speed and good lubrication conditions
Application scenarios
SKF combined beads are particularly suitable for the following application scenarios:
Space limited: When other types of positioning bearings require excessive space, combined bearings can provide a more compact solution.
Heavy axial load: In applications that require bearing large axial loads, combined bearings can provide better support.
High speed: In high-speed applications, combined bearings can ensure good lubrication and stability.
Poor lubrication conditions: In situations where lubrication conditions are poor, combined bearings can provide better lubrication effects
SKF Combined Bearings are advanced bearing solutions that integrate multiple bearing functions into a single compact unit. These bearings combine radial and axial load-handling capabilities, often merging needle roller bearings with thrust bearings or angular contact designs to optimize performance in space-constrained applications. Engineered for high precision and durability, SKF Combined Bearings are ideal for robotics, automotive systems, industrial machinery, and aerospace equipment where compact design and multi-directional load support are critical.
