Angular contact spherical roller bearings have sphered sliding surfaces on the inner and in the outer ring which are arranged at an angle to the bearing axis. They are therefore particularly suitable for carrying combined (radial and axial) loads. A single angular contact spherical plain bearing can only accept axial loads acting in one direction. Under radial loads, a force acting in the axial direction is produced in the bearing which must always be opposed by an equal force acting in the opposite direction. Therefore, the bearings are usually adjusted against a second bearing. If two angular contact spherical roller bearings are arranged so that their sphere centres coincide, a spherical plain bearing is obtained which can accommodate heavy radial loads as well as heavy axial loads in both directions.


SKF angular contact spherical roller bearings are produced as standard with the sliding contact surface combination steel/PTFE composite. They are primarily intended for loads of constant direction and are maintenance-free. However, to enhance protection against corrosion and to improve sealing, it is recommended in many applications, that the space surrounding the bearing be filled with a rust inhibiting lithium base grease of consistency 2 or 3 during mounting. Such an initial lubrication also extends the effective service life of the skf bearing.


In addition to ball and roller bearings SKF also produces a comprehensive range of spherical plain bearings and rod ends and has a choice of materials for plain and flanged bushings as well as thrust washers.


To select a certain bearing type and to establish the requisite bearing size, the main factors which have to be considered are the loads, the load carrying capacity of the bearing and the expected service life. The same is true when selecting a rod end.


You can buy Sealmaster Bearings products like mounted bearings, rod ends and spherical roller bearings at any of your local stores, but if you cannot find your preferred iko bearing type, you can always shop online.spherical roller bearings are used to support shafts or even rods with various numbers of misalignment. They're made to regulate high radial loads and offer constant performance under conditions of marginal lubrication, excessive speed and critical-application stress. Most spherical plain bearing includes a plain bearing and ball bushing in the lined, cylindrical housing that will minimizes friction or provides self-lubrication. Lubrication-free spherical plain bearings can also be found. 


Generally, metal balls and liners are made from steel, bronze or golf iron. Non-metallic balls and liners are often made from nylon, cheap, or polytetrafluoroethylene (PTFE). Each of those metallic and non-metallic merchandise supply superior performance to help traditional steel, plastic and also bronze plain bearings. With regard to heavy-duty industrial applications, [spherical roller bearings]  can include large bores or spherically shaped rollers which allow axial running and relative misalignment relating to the housing and shaft.
