SXL Rudder Bearings

15-Year Rudder Bearing Guarantee for Newbuilds
SXL Rudder Carrier Bearing

Reliability, long wear life and superior customer service have made Thordon the first choice in pollution free rudder bearing applications for over 25 years with an impressive reference list of over 4000 vessels. Thordon SXL self lubricating pintle, stock and carrier disc bearings operate grease-free, above and below the waterline.

For newbuildings, Thordon Bearings offers a 15 year bearing wear life guarantee or for conversions offering twice the life of the replaced material to a maximum of 10 years. Both guarantees are unmatched by any other rudder bearing supplier. With a worldwide distribution network Thordon rudder bearings can be delivered fast to any ship repair facility in the world.

Thordon SXL rudder bearings offer low friction, operating pressures up to 12 N/mm2 (1740 psi) and the complete elimination of grease and greasing systems removing any risk of pollution. Thordon SXL can also withstand high shock loads and edge loading.

In addition to SXL pintle, stock and carrier disc bearings, SXL TRAXL or ThorPlas, can be specified grease free in steering and linkage applications, as well as fin stabilizers. In workboat applications, ThorPlas is recommended for the more highly loaded bushings in the tiller arm and "jockey-bar" linkages. Both products operate grease free saving you time, money and the risk of pollution.

Thordon self lubricating rudder stock seals provide exceptional wear life, completing the rudder bearing package.
