SKF has launched the MUD11 cassette seal for wheel ends to help improve the performance of equipment such as agricultural and construction machinery.

New design features extend the life of the seal while reducing friction and the possibility of dirt entering.

In addition, the MUD11 seal is now available as a stock product, making maintenance and replacement more efficient.

“Improvements help end users increase productivity while reducing both maintenance and operating costs.” – says Vinay Joyappa, SKF’s global product manager.



MUD11 seals protect the wheel end bearings to prevent damage to equipment such as tractors and construction vehicles. A typical example is at harvest time, when agricultural machinery has to maintain performance in harsh conditions. The front and rear axle wheel bearings must withstand high and continuous loads for a long time while resisting dusty or dirty environments. The MUD11 seal helps with this challenge.

New features in the seal include an optimized multi-lip design, the use of an integrated metal sleeve and a blend developed by SKF.  These refinements increase bearing life by up to 50% while reducing initial seal friction by approximately 20%. This can also help OEMs and distributors extend the life of their wheel ends and reduce warranty claims. In addition, it becomes unnecessary to machine the expensive shaft.
In addition to eliminating dirt more effectively, the MUD11 is easier to install than its predecessor with the new multi-lip design. Moreover, the new seal can be retrofitted into an existing groove using a two-stage assembly.
Seals also offer customers a number of sustainability benefits. These include preventing leakage of lubricant; extends both bearing life and seal life; and reducing friction (leading to lower energy consumption).
Available as a stock item, MUD11 seals are easily accessible via SKF’s distribution network. This helps users reduce customer inventory, while localized purchasing helps reduce import duties.
