JTEKT develops Ball Bearing with High Muddy Water Resistance Seals for agricultural machinery
【Image of developed bearing】
1.Background of the development
Tractors and planters (attachment of tractor for sowing seeds) are used under harsh conditions in muddy water and it has been taken for granted, so far, that they should be replaced or overhauled after a short life cycle.
【Results of 400 hours of mud resistance evaluation】
2.Features of the New Product
Conventional sealed bearings for agricultural attachments have two radial lips for improved mud resistance, however, this new product has an additional axial lip in addition to the radial lip to optimize the geometry, reduce torque and achieve high sealing performance.
(1) 3-lip, shape optimization and shield labyrinth resulting in more than doubling of the mud resistance
(2) Optimized seal geometry reduces torque by 40%
