SKF Three-barrier solution

For highly contaminated environments, SKF recommends the SKF Three-barrier solution, as contaminants must pass through three barriers to reach the bearing. 

The SKF Three-barrier solution extends bearing service life without the use of large quantities of grease to purge contamination. This SKF solution consists of:

  • Sealed SKF Explorer spherical roller bearings
  • SKF split block housings
  • Standard SKF L or S-type seals for SNL housings and Posi-Trac Plus seals for SAF and SAFD housings
  • SKF LGGB2 biodegradable or LGEP2 as the barrier grease

Designed and proven to perform

SKF Explorer spherical roller bearings can accommodate very heavy radial and axial loads in applications prone to misalignment or shaft deflection. Efficient contact seals and factory-filled high quality grease make the units ready to use.

SKF Explorer spherical roller bearings provide a significant improvement in key operational parameters and have proven to last several times longer than competitor's bearings when tested under typical heavy-duty conditions. This is especially true for SKF sealed spherical roller bearings, where the extraordinary sealing performance leaves the competition far behind.

SKF Taconite Seals

Fine-grained taconite and high pressure water wash is extremely difficult to keep out of bearing arrangements, particularly in mining and cement applications. SKF Taconite Seals are labyrinth seals that are up to the task.

When SKF Taconite Seals are used with SKF split housings and sealed spherical bearings, it becomes the "ultimate" SKF Three-barrier solution.
