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.

In addition to protecting against external contaminants, dust wiper seals also help to retain lubricants within the system. This is particularly important in applications where proper lubrication is critical for preventing friction and wear. By maintaining a stable lubricant film, dust wiper seals enable machinery to operate smoothly and efficiently, ultimately extending the lifespan of the equipment.
The dimensions of the oil seal, 20x35x7, refer to its inner diameter, outer diameter, and thickness. These specifications determine the compatibility and performance of the seal in different applications. The size of the oil seal must be carefully matched to the shaft or housing it is intended to seal to ensure a proper fit and effective function.
