Cassette seals

The design of SKF Mudblock cassette seals has been optimized to provide excellent retention of either grease or oil and maximum protection against liquid or solid contaminants. The seals are made to order to meet the demands of each specific application.

SKF Mudblock seals are widely used in wheel-end applications such as the front and rear axles of, for example:
  • Tractors
  • Agricultural machinery
  • Construction equipment
  • Forestry equipment
  • Off-highway trucks

SKF Mudblock seals MUD6

For grease-lubricated applications

SKF Cassette seal design MUD6 is a cassette seal, specifically developed for grease-lubricated heavy-duty applications in harsh environments and tough operating conditions. Also called SKF Mudblock seals.

SKF Cassette seals MUD6 are designed for use in grease lubricated applications and provide features including:

  • Rubber outside diameter for reliable seal retention in the bore as well as improved sealing performance
  • Rubber covered inside diameter for improved sealing performance and easy installation
  • Integrated wear sleeve
  • Bumper maintaining the relative position between the seal and the sleeve as well as acting as a barrier against contaminants
  • Auxiliary radial lips for contaminant exclusion

SKF Mudblock seals MUD11

For oil-lubricated applications

SKF Mudblock seal design MUD11 is a new generation of cassette seals, specifically developed for oil-lubricated heavy-duty applications in harsh environments and tough operating conditions.
SKF Mudblock seals MUD11 are designed for oil-lubricated applications and provide features including:

  • Half-metal/half-rubber outside diameter – improves static sealing, heat dissipation and retention in housing
  • A unitized, multi-lip seal design
  • Axial and auxiliary radial lips for contaminant exclusion
  • Integrated stainless steel wear sleeve, curled for a reliable unitized solution to facilitate installation and prevent damage to the lips during transportation, handling and installation
  • High-performance elastomeric materials
  • Market-leading performance in terms of oil retention
  • Offer robust protection from solid and liquid contaminants while reducing friction and extending seal service life
