Founded in 1995 and as a member of China National Crane Conveyor Machinery Association, China Chuanda Conveyor Belt Co., Ltd. is a specialized plain bearing, spherical plain bearing manufacturer and custom plain bearings, spherical plain bearings designer of various kinds of conveyors, belts, pulleys, bearings, rollers, bushings and so on. Through modern scientific management, excelsior products and technological design, advanced production tools and strict testing methods, we have produced various types of conveyance equipment. In 2001, we were certified by ISO9001: 2000, which has ensured the reliability and stability of product quality. Also, we have passed Germany DQS authentication in the domestic same trade. We have established long-term relationships with some famous mechanical manufacturers both at home and abroad, such as Veit GmbH, Hashima, Oshima, Summit, and KDK companies.

Characteristics: they can bear radial, axial load and their combined load, have big load capacity and characteristics of wear-resistance, wear-corrosion, self-aligning and self-lubricate.Series: radial spherical plain bearings, angular contact spherical plain bearings,spherical plain thrust bearings, rod ends, ball joint rod ends.
Spherical plain bearing is a kind of special structure bearing.Its build-up by a outer spthere of inner ring and a inner sphere of out ring.It can be submitted to high load.According to its different types and structures,it can be submitted by the radial load and axial load or both of them together.Due to the composite material on the outer sphere of inner ring,this kind of bearing can be maintenance-free.It work in low speed pendulum motion,and also can work in steeve motion at prescript angle.It still work when the shaft and shaft casing pore are at non-concentricity.

LS radial spherical plain bearings requiring maintenance(steel-on-steel) have hardened sliding contact surface on both rings. The surfaces are treated with molybdenum disulphide and phosphated. It has characteristics of wear-resistance and wear-corrosion. Bearings with this sliding contact surface combination require regular relubrication.The high strength of the sliding contact surfaces makes these bearings especially suitable for bearing arrangements where heavy loads of alternating direction, shock loads or heavy static loads have to be accommodated.
These bearings are determined for arrangements where great radial forces at slow tilting or oscillating are acting and for arrangements where space adjustability
for both components is secured.
