Spherical Plain Bearing

Joint bearing is a type of spherical sliding bearing, with a sliding contact surface consisting of an inner spherical surface and an outer spherical surface, allowing for rotation and swinging at any angle. This type of bearing is made using various special processing methods such as surface phosphating, blasting, padding, and spraying, and has the characteristics of high load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning, and good lubrication. The structure of joint bearings is simpler than rolling bearings and can withstand larger loads, especially suitable for low-speed swinging, tilting, and rotating movements. According to different application requirements, there are various types and structures of joint bearings, including radial joint bearings, thrust bearings, rod end joint bearings, etc. Each type has its specific characteristics and applicable scenarios. For example, radial joint bearings mainly bear radial loads and small axial loads in any direction, while rod end joint bearings can simultaneously bear large radial loads and bidirectional axial loads, with greater load capacity and impact resistance. In addition, there are various options for joint bearings, such as maintenance free and regularly lubricated types, to meet different working environments and maintenance needs. Due to these characteristics of joint bearings, they are widely used in various mechanical fields, such as construction machinery, heavy-duty vehicles, textile machinery, etc., as well as in situations where low-speed rotation and tilting motion within a certain angle range are required.
