Radial shaft seals | SKF

A sealing lip made of an elastomeric or thermoplastic material that seals dynamically and statically against the shaft. The lip has a sealing edge that is formed by moulding, cutting or grinding. It is normally pressed against the counterface surface of the shaft, with a defined radial load, by a garter spring.

What's the Difference Between Lip Seals & Non-Contact Seals?

LIP SEAL NON-CONTACT SEAL; Wear: by friction: none: Power Loss: by friction: no power loss: may lead to energy savings & smaller units: Speed Limit: material dependent: none: Live Tool: oil lubrication: if oil level below sealing diameter oil mist lubrication: water: limited, as water may increase the friction at sealing location.

Sealing lip design | SKF

The form and design of a sealing lip is based on knowledge gained through research and development activities as well as wide practical experience obtained by SKF in close cooperation with users. The distance between the lip and the seal back face, the strength of the flex section, the angle of the lip ( fig 1) and the tension in the spring are

Lip-Seal vs O-Ring - Restore An Old Car

The o-ring piston seal was designed to alleviate the relaxing lip seals, but the reduced piston to wall clearance inherent with the o-ring design (when installed in a floating piston caliper), eliminates what Duntov said was necessary. The designed-in balance between the lip seal and the piston spring is lost with O-ring pistons (the purpose of

Oil Seals and Grease Seals Selection Guide: Types, Features

For proper installation, the seal lip should point towards the medium being contained. Some oil seals and grease seals have a spring to help keep the lip in contact with the shaft. Oil and grease seals are used to retain or separate lubricants or fluids. These seals are primarily used for rotary applications only. Types,
