IKO Spherical plain bearing

The spherical plain bearing is a kind of spherical sliding bearing. Its sliding contact surface is an inner spherical surface and an outer spherical surface. It can rotate and swing at any angle during movement. method made.

The spherical sliding contact area of the spherical plain bearing is large and the inclination angle is large. At the same time, because most of the spherical plain bearings have adopted special processing methods, such as surface phosphating, galvanizing, chrome plating or outer sliding surface lining, padding, spraying, etc. It has large load capacity and impact resistance capacity, and has the characteristics of corrosion resistance, wear resistance, self-alignment, good smoothness or self-smoothing without smooth dirt purification, and can work normally even if the device is dislocated. Therefore, spherical plain bearings are commonly used for low-speed rocking motions, tilting motions and rotational motions.

In any case, the selected fit of the spherical plain bearing shall not cause uneven deformation of the ferrule, and the selection of its fit and grade must be determined according to the working conditions such as bearing type, support form and load size.

Oil-fed spherical plain bearings can be operated without lubrication when the applied load and the velocities generated by the oscillating motion are very small. Nevertheless, it is generally necessary to replenish the grease regularly. In the initial installation and operation, it is recommended that the lubrication cycle should be appropriately shortened.

 Oilless spherical plain bearings can be used without lubrication. However, the life of the spherical plain bearing can be extended even further when lithium soap-based grease is added before operation. If grease is injected into the space around the bearing, the spherical plain bearing will be more effective in preventing the intrusion of dust and foreign objects.
