Spherical plain bearings Technological developments have helped industry find ways to solve problems and improve productivity. The advancements in bearing technology have helped develop certain bearing designs that can not only manage heavy loads but also handle misalignment while functioning under conditions that are unfavorable and harsh. A spherical plain bearing is so designed to have standardized and detachable components to facilitate quick interchangeability and accommodate alignment movements in both directions while handling heavy loads.
This type of bearing has the static forces acting on it while oscillating and slewing at relatively low speed. It is constructed using sliding contact surfaces, inner and outer raceways, rollers and a cage. The innate feature of the bearing is the sphered rings, with the inner being “convex outside diameter” and the outer being “concave inside surface”. To suit certain heavy applications carried under extreme conditions, a spherical plain bearing is made using high-quality carbon chromium steel, which is hardened, as well as phosphate-coated to save getting fatigued while carrying and transferring loads along the sliding contact surfaces. They are corrosion-resistant and undergo self-lubrication during operation. Know the Distinguishing Features of Spherical Plain Bearings Unlike other types of bearings, a spherical bearing is recognized for its cutting-edge design, which offers the following characteristics:
Some Common Types of Spherical Plain Bearing There are quite a few kinds of spherical plain bearings used in industry. The popular ones are the angular contact spherical plain bearing, radial spherical plain bearing, spherical plain thrust bearing, etc. When compared to the angular contact ball bearings, the angular contact spherical plain bearings are distinctive with “spherical sliding contact surfaces”. This enables them to handle both radial and axial loads. You can also find the following types of spherical plain bearings:
You can have variations in the design of aspherical plain bearing by adding certain accessories like brackets, pillow block bearing, etc.
