Agricultural machinery bearings is a widely applied abroad agricultural machinery special sealed ball bearings. It is based on the disc plough, harrow and farming machinery transmission load large, easy cultivation in slurry into the bearing, the working shaft ( the plow shaft or harrow shaft ) equidistantly installed sleeve bearing characteristics, specially designed a good sealing performance, good aligning performance, large capacity, easy assembly and disassembly bearing.

Agricultural machinery bearings with special structure, the inner hole of cylindrical, four square, six square; the outer diameter of a cylindrical, spherical, cylindrical spherical mixed. Some bearing is also provided with a square hole or a circular hole punching bearing seat, the bearing can simplify the host structure, and is convenient for mounting, dismounting bearing.

Agricultural machinery bearing seal ring structure is very special, is a hemming steel skeleton three layers of rubber lip large interference contact type sealing ring. It can block the external bearing clay, sand ingress of water, and can prevent the bearing lubricating grease inside the loss, good sealing performance.
