1.Abstract: Spherical roller bearing is also an important kind of bearings. The raceways in the outer ring of this type bearing are designed with a spherical surface whose center coincides with the bearing centerline. Part of the outer ring raceway is spherical, with internal self-aligning bearing performance to meet the whole axis and the seat relative deviation. Radial heavy duty and can withstand shock loads, but also bear some of the bi-directional axial load. The bearing shell limits the axis or axial displacement in the axial bearing clearance range. 2.Specifications: 1)Market:Mid East&Africa 2)long life&low noise 3)ISO9001:2000 4)competitive price ,good service 3.features: low voice, high speed, long life 4.Application home appliances: low noise and high speed electric motors, auotomotive components, pups, machinery, Bicycle.
