Automotive Bearings

Bearings widely used in kinds of transmission and rotation parts of automobile,truck and trailer.

Slewing bearings: WD Slewing bearings are all the support needed between the two parts relative to bear the axial rotation and at the same time, and radial force and overturning moment of the machinery-based components. Its basic function is to be fixed bolts used in machinery and equipment of the upper and lower bearings, and a power-transmission, and machinery and equipment between the two parts of the relative rotation. Slewing bearings are generally installed with a hole in gear, or gear, lubrication and seal holes, a compact, light weight, structural steel and good, smooth operation and high precision, secure, reliable and so on.

Angular contact ball bearing: Angular contact ball bearings can bear not only axail but also radial loading capacity.Though only bearing unilateral axial loading capacity, they can be used together with the bearings bears opposite axial loading capacity. Angular contact ball bearings, with a limit ability to self-aligning,can not be dismantled.

Water pump bearings: Water pump bearings is a double supporting bearing with a simplified structure, which constitutes no inner ring for the two supporting bearing, groove for rolling element directly made on the shaft, the outer rings of the two bearings made to a unity and two sides of the bearing closed by rubber seals.In the condition of same loading capacity, the radial dimensions are usually smaller than those of same kind; while in the condition of same radial dimensions, the loading capacity is usually heavier. Because of its good steel capacity and easy rotation and structure, they are used by many developed countries including USA, Japan, Germany and so on.

Taper roller bearings: Taper roller bearings can be dismantled, whose inner ring, assembly part made by rollers and cage, outer rings can be separately assembled. The amendatory contact line in the contact place of rollers and grooves can reduce the concentration of stress. Taper roller bearings, which can bear not only heavy axial but also heavy radial loading capacity, need to be used together with a symmetrically assembled one to transfer the opposite axial loading because of its just ability of transferring the unilateral axial loading capacity.

Spherical plain bearings: Spherical plain bearings, a kind of special sliding bearing,which can bear quite heavy loading capacity, are with a simple structure made of outer-spherical inner ring and inner-spherical outer ring. In accordance with different type and structure, this kind of bearing can afford loading capacity of radial, axial and combined directions.As used in swaying movement in low speed (that is angular movement), it can still work.

Linear bearings: Linear bearings, manufactured with low cost, are used in limitless journey or used to work in column.As loading ball contacts the shaft at certain point, the bearing application loading capacity is quite small. With rotation of ball with a quite slight friction resistance, high-precise level movement can be obtained. Linear bearings are widely used in precise equipments such as electronic equipment, pull measuring machine,numeralization 3-D measuring equipment, etc; and slip part of industrial machines such as multi-shaft machine, punching machine, tool grinder, auto steam cutting machine, printer, card selection machine, food packing machine and so on.
