Process and rotary motion of the metric ball joint rod ends

- Sep 07, 2018 -

The metric ball joint rod ends are a spherical plain bearing, and its basic type is composed of an inner and outer ring having a spherical sliding spherical contact surface, and the joint bearing is mainly composed of an outer ring having an outer spherical surface and an outer ring having an inner spherical surface. Can withstand large loads when operating. Depending on its type and construction, it can withstand radial loads, axial loads or combined loads in both radial and axial directions.

The metric ball joint rod ends are provided with a composite material on the outer spherical surface of the inner ring, and the bearing can be self-lubricated during operation. Generally, it is used for low-speed swing operation, and can also be tilted in a certain angle range. When the support shaft and the shaft hole have different degrees of centering, they can still work normally. 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 metric ball joint rod ends therefore needs to have a large load capacity and impact resistance when used, and has the characteristics of corrosion resistance, wear resistance, self-aligning, lubrication or self-lubricating and non-lubricating dirt when used. Even if the installation is misplaced, it will work properly. Therefore, joint bearings are widely used for low-speed oscillating motions, tilting motions, and rotational motions.
