Customized non-standard Spherical Plain Bearing

Short Description:

Applicable conditions of plain bearings:

  • Suitable for static and dynamic overloads
  • Multidirectional motion
  • Allowable misalignment
  • Basically eliminate the marginal stress and excessive stress of adjacent components
  • Allowable deformation of surrounding parts during operation
  • Large manufacturing tolerances are allowed, and low-cost welded components can be used

Why Choose Us



We can fully comply with your drawing requirements. According to your work envoronment, our technical engineer also will provide you with professional technical advice, so as to give you a practical bearing.


Suitable Lubrication

Our bearing's life is longer than others because of  first-class grease and oil.We use  premium grease  to help improve performance and extend life of our bearing, reduces torque and temperature, enables greater bearing roller traction, enhances protection against wear, rust, and contamination.

How to Select Size


Load Direction

Radial load

Axial load

Combined (axial and radial) loads

Load Type

Dynamic load, which means there is relative sliding in the load bearing

Static load,which means no relative sliding in the loaded bearing

Loading conditions

Constant load, which is the direction of load action is unchanged, and a part of the bearing (load area) is always under this load

Alternating load, which is the changing load direction, makes the load area at the opposite position in the bearing in the alternating load and unloading.
