JPG Bearing

Plane thrust needle roller bearings (commonly known as plane bearings or plane needle roller bearings) are composed of a thrust cage and needle rollers or cylindrical rollers plus thrust washers. The bearings mainly bear axial force, thrust needle roller bearings and thrust roller bearings The components can be used alone or in conjunction with washers. They have diverse structures, high load-bearing capacity and high rigidity. They are widely used for positioning and supporting of mechanical equipment such as automobiles, machine tools, metallurgical machinery, textile machinery, motors, transmission shafts, gearboxes, etc. .

main feature:

Withstand one-way axial load and play a thrust role;
The axial section height is small, saving installation space;
High axial accuracy.
The structure is shown in the following table:
