Inch U-shaped forks can withstand a relatively large load to a certain extent, and can effectively bear the combined load of radial load, axial load or radial and axial simultaneously according to different types and structures. Since the outer surface of the inner ring is provided with a composite material, self-lubrication can be produced during operation.
Inch U-shaped fork can be effectively used for a lower speed of swinging motion to a certain extent, or it can be tilted in a certain angle range. To a certain extent, when the support shaft and the shaft shell hole are different in center of gravity At the time, it still works. Self-lubricating joints are used in water conservancy and professional machinery industries. Because the spherical sliding contact area of the joint bearing is large, the inclination angle is large, and because most of the joint bearings adopt special processing methods, such as surface phosphating, galvanizing, chrome plating or outer sliding surface lining, inserting, spraying and the like.
The British U-shaped fork has large load capacity and impact resistance, and has the characteristics of corrosion resistance, wear resistance, self-aligning, lubrication or self-lubricating and non-lubricating dirt pollution, even if the installation is misaligned. Therefore, joint bearings are widely used for low-speed oscillating motions, tilting motions, and rotational motions.
