Mudblock seals for off-highway applications

Designed to extend seal service life, the solution can reduce seal friction by up to 20%, offering off-highway customers a solution that reduces energy loss and thus increases efficiency. The seal features a multilip cassette seal design incorporating optimised lip geometry, stainless steel counter surface and a specially formulated nitrile compound to reduce wear and aging. This increases bearing life by preventing the ingress of contaminants and retaining the lubricant inside the bearing, thus also minimizing environmental impact due to oil leakage. "The main customer need that this solution addresses is increased reliability – something all off-highway OEMs strive for, as customers may gain up to 50% longer seal operating life," said SKF global product manager Vinay Joyappa. The SKF Mudblock cassette seal comes in a range of sizes from 25 to 250mm shaft diameter and is interchangeable with other cassette seals.
