The design of PU oil seals also plays a significant role in their functionality
pu oil seal. They often feature a-like structure that creates a tight seal against the mating surface, preventing the leakage of oil or other fluids. This design, combined with the elastic memory of polyurethane, allows the seal to recover its original shape after compression, maintaining a consistent seal even under fluctuating pressures.

3. **Roller Assembly** The roller assembly is the heart of the tapered roller bearing. It includes the tapered rollers and the cage (or retainer). The rollers, shaped like truncated cones, distribute the load evenly across their length, reducing stress points and enhancing bearing life. The cage keeps the rollers separated and in place during rotation The cage keeps the rollers separated and in place during rotation
