Project Description

Oil Seals / Radial Shaft Seals

Oil seal, also named radial shaft seal or Simmerring,  is designed for sealing shafts and spindles. It’s one of the most frequently used rotary shaft seal. It separates oil or grease on the inside from dirt, dust and/or water on the outside. Most commonly, Oil-seal consists of a rubber sealing lip, a metal housing and a helical tensioned spring.

We supplie various types of oil seals, both with and without dust lip, in accordance with DIN3760/3761 and ISO 6194. Standard available in NBR/Steel and FKM/Stainless steel. Besides the standardised sizes, we also designs special and custom oil-seals.

APPLICATIONS

The common radial oil seals works by creating a thin layer of oil between the rubber sealing lip and the shaft which results in the oil lifting the sealing lip clear of the shaft. This thin layer of oil performs a barrier and prevents leakage of the oil past the sealing lip. For this reason rubber oil seals are not suitable for dry running applications or high pressure.

Typical applications include:

  • Power transmission

  • Oil refineries

  • Off-highway

  • Manufacturing

  • Automotive
