ROD END BEARINGS AND ASSEMBLIES Description of bearing types Male, female or spherical bearings are ready-to-use mechanical components, based on the journal bearing principle. These components are used in mechanical construction to transmit static or dynamic forces at different angles. The design of bearing components is governed by the
DIN / ISO 12240 standard, which also speci Bearing components can be self-lubricating or fitted with grease nipples. Schaublin SA produces spherical bearings to this standard, but we also offer custom engineer and produce spherical bearings to meet the customer's needs. Operation and Uses The function of the bearing component is to transmit a static or, more frequently, a dynamic force, under particular angular or rotation conditions. Spherical bearings supplement ball bearings or other casings in slow
movements. They are also able to withstand high loads because of the large
surface contact area. An inner bush or ball is generally made from hardened chrome steel, pivots and tilts within a spherical cavity (the cage or outer ring). These two parts form a bearing that is held in a support structure, a rod body, or housing. The support will have either threaded rod (the male support) or a hollow tapped shank (the female support) enabling users to attach the bearing component to its assembly. The bearing may also be cylindrical (like a ball bearing), thus allowing users to insert it into their assembly. The body of spherical bearings can be made from various materials: standard steel, high grade steel, stainless steel or aluminium. The internal surface of the cage, or outer ring, which goes onto the inner bush is made of bronze (and will be lubricated) or self-lubricating material (PTFE). What are the Applications ? There are many applications in which spherical bearings may be used, among them : Industria
