Single-Direction Thrust Spherical Roller Bearings
The one-way thrust spherical roller bearing is a rolling bearing that can withstand unidirectional axial loads. It has a self-aligning function and can automatically adapt to the deflection of the shaft and the seat hole to reduce the impact of misalignment. Its main features include:
- One-way load: can only withstand axial loads in one direction.
- Self-aligning ability: can automatically adjust the deflection of the shaft and the seat hole to reduce the impact of misalignment.
- High load capacity: the roller design enables it to withstand large axial loads.
- Low friction: low rolling friction and high operating efficiency.
- Long life: reasonable design and long service life.
Vue d'ensemble
Single-direction thrust spherical roller bearings are designed to withstand unidirectional axial loads and have automatic self-aligning functions. Its core structure includes an inner ring, an outer ring, rollers and a cage. It adopts a double-row logarithmic curvature roller design, has excellent self-aligning performance, and can effectively offset the deflection and installation deviation of the shaft. This type of bearing not only has a strong load-bearing capacity, but also can resist impact. It is suitable for low-speed or medium-speed operating environments and can remain stable even under harsh working conditions. The inclined contact design of its rollers and raceways optimizes the load distribution and reduces stress concentration, thereby extending the service life and improving operating efficiency.
