Lipped seal 2221400001

FKMfor oil

The rotary shaft seal, also known as radial shaft seal, or oil seal,​​​​​​ provides sealing around a rotating shaft. The primary media to be sealed are oils and lubricating greases. Techné offers the most common profiles, standardized to DIN 3760/3761. Different profiles and materials are chosen based on the nature of the fluid, the level of external contamination, the qualities of the shaft and housing, shaft speed, temperature, pressure, etc. The difference between the SL and DL profiles lies in the presence of an additional dust protection lip in the DL. Upon request, the seals can also feature a helix on the lip.
