Thrust needle roller bearings AXK AXW AX NTA series
Thrust needle roller bearings or thrust cylindrical roller bearings are a set of needle rollers (rollers) with cages arranged between a set of rollers and washers. The cages reliably guide and hold a large number of rolling elements. The rolling elements in the same assembly are only There are extremely small differences. Thrust needle roller bearings or thrust roller bearings can only support axial loads in one direction, and can be used as bearings with good rigidity and the smallest axial space. The standard cages of thrust needle roller bearings and thrust roller bearings are stamped steel cages. For roller sleeves with cages, a structure that can be guided by the inner diameter or outer diameter must be adopted.
Thrust washers AS LS GS WS series
Thrust washers AS series are stamped from high quality spring steel. It is 1mm thick, hardened and polished. When the surface of the adjacent parts has good rigidity but is not suitable for rolling, the AS series gaskets give full play to its role. Thrust washers GS WS LS series are made of bearing steel and hardened. The outer surface of the seat washer GS and the inner surface of the shaft washer WS are ground. The LS is a particularly economical car-built exterior and interior. Thrust needle roller bearings or thrust cylindrical roller bearings are between a set of raceway rings (WS type and GS type), equipped with rollers with cages (AXK type or K type), which can only bear a single bearing load .
When using roller sleeves with cages, the design can be made compact because the shaft or bearing chamber is directly used as the rolling contact surface. At this time, the rolling surface must have a hardness of HRC58-64 and a finish of 0.4a or more. For needle roller bearings, a thin-walled steel ring (type AS) is used as the ring, so that a compact design can be achieved even when the shaft or bearing chamber cannot be heat treated and finely ground.
