Radial shaft seals

When oil leakage is not an option

Radial shaft seals
Oil leakage must be avoided in industrial geared units. This is a growing challenge due to the increasing use of aggressive oils, threatening reliable sealing performance. 

To meet these performance challenges, SKF radial shaft seals are designed to provide an optimized radial load and are manufactured using a unique compound, specifically engineered to offer better oil compatibility. Together, these features provide improved sealing performance. Additionally, SKF SPEEDI-SLEEVE and wear sleeves provide the most suitable counterface for damaged shafts.

SKF Speedi-Sleeve

The fastest, most economical way to optimize shafts or repair worn shafts

Over time, contaminants and conditions can cause particles to become trapped inside a lip seal. Particles then form wear grooves on the shaft, eventually leading to seal failure and severe shaft damage. Repairs are expensive, time-consuming and too often, ineffective. With an SKF Speedi-Sleeve, they are unnecessary.

Optimized seal counterface surface

The new generation SKF Speedi-Sleeve uses a proprietary stainless steel material and manufacturing process, resulting in an optimized seal counterface surface that minimizes wear on both sleeve and sealing lip. An SKF Speedi-Sleeve mounts quickly and easily without power tools or heating.

Often capable of delivering a better quality counterface for the seal lip than the original shaft, SKF Speedi-Sleeve also:

  • Eliminate expense of replacing or reworking shafts
  • Require no shaft disassembly or machining
  • Enable same size replacement seal as original
  • Provide an excellent, wear-resistant sealing surface
  • Are easy to install with no power tools or heating
