Thrust Spherical Plain Bearings

Thrust spherical plain bearings have a convex spherical surface on the shaft washer and a corresponding concave spherical surface in the housing washer. They are intended to accommodate primarily axial loads but can also accommodate radial and axial loads. The shaft and housing washers are made of bearing steel that has been through-hardened and ground. The sliding surface of the shaft washer is hard chromium plated and coated with lithium base grease. The sliding layer of fiber-reinforced polymer containing PTFE is injection molded onto the housing washer.

Five issues to be aware of when using the thrust spherical plain bearings

(1) Working temperature of thrust spherical plain bearings

Thrust spherical plain bearings allowed working temperature is mainly composed of thrust spherical plain bearings is determined by the material of the matching between the sliding surface, especially the type self-lubricating thrust spherical plain bearings of the sliding surface, plastic materials at high temperature with the decrease of the carrying capacity of the trend. Such as lubrication type thrust spherical plain bearings when the sliding surface of materials matching for steel/steel, its allowable working temperature depends on the permissible operating temperature of the lubricant. But for all types of lubrication and self-lubricating thrust, spherical plain bearings can be in the - 30 ℃ ~ 80 ℃ temperature range of use and keep the right to bear ability.

(2) Angle of thrust spherical plain bearings

Thrust spherical plain bearings are far better than the Angle adjustable heart of rolling bearing is much more commonly, very suitable for use in supporting parts of the concentricity requirement is not high, the Angle of joint bearing on bearing structure size, type, sealing device and reinforcing form is different. Generally, the centripetal range Angle is 3 ° ~ 15 °, angular contact bearing joints Angle range is 2 ° ~ 3 °, and thrust spherical plain bearings Angle range is 6 ° ~ 9 °.

(3) Thrust spherical plain bearings' cooperation

In any case, thrust spherical plain bearings choose cooperation shall be uneven deformation in the ring. Its nature and the level choice must come according to the bearing type, such as supporting form and the size of the load working conditions to decide.

Loading and unloading of thrust spherical plain bearings should follow the following principles. Namely, the force imposed by the assembly and disassembly can't directly pass through the spherical sliding surface. In addition, it should use auxiliary loading and unloading tools, such as sleeve, dismounted, etc.; the loading and unloading force exerted by the outside world should be directly and evenly applied to the matching ring or use the auxiliary method such as heating to load and unload without load.

(4) The installation of thrust spherical plain bearings

When assembling the thrust spherical plain bearings series, it is necessary to give special attention to the outer ring segmentation position below. To avoid the load acting directly on the segmentation surface, the segmentation surface should be maintained at a right angle with the corresponding direction.

(5) Thrust spherical plain bearings lubrication

When the applied load and produced are very hour, the speed of the swinging motion to the oil type thrust spherical plain bearings can operate in the case of no lubrication. However, regular oil and fat supplementation are generally necessary. During the initial installation and operation, it is recommended that the lubrication cycle should be moderately shortened.

No oil-type thrust plain spherical bearings can be used without lubrication circumstances. However, before the operation to join lithium soap base grease, thrust spherical plain bearings service life will be extended more. If dimensional infuse grease around the bearing, thrust spherical plain bearings will be more effective protection from dust and the invasion of foreign bodies.
