Spherical Plain Bearings Structure Spherical plain bearings are made with through-hardened bearing steel and are available with different sliding contact surfaces. When a bearing is steel-on-steel (or metal-on-metal), it is an economical solution for many applications, however, it requires maintenance.
How are plain bearings made?
Metal-polymer plain bearings consist of a metal backing, usually steel or bronze, onto which is sintered a porous bronze layer that is then impregnated with PTFE and additives to obtain a running surface that offers anti-friction and wear resistant bearing properties.
How are spherical roller bearings made?
Spherical roller bearings consist of an inner ring with two raceways inclined at an angle to the bearing axis, an outer ring with a common spherical raceway, spherical rollers, cages and, in certain designs, also internal guide rings or center rings. The bearings can also be sealed.

What are spherical plain bearings used for?
Spherical plain bearings are used to accommodate shafts or rods with varying amounts of misalignment. They are designed to manage high radial loads and provide consistent performance under conditions of marginal lubrication, extreme speed and critical-application stress.
What is a plain bearing type?
A plain bearing, or more commonly sliding contact bearing and slide bearing (in railroading sometimes called a solid bearing, journal bearing, or friction bearing), is the simplest type of bearing, comprising just a bearing surface and no rolling elements.
What are spherical bearings made of?
Inner rings of maintenance-free spherical plain bearings are made of hardened carbon chromium steel, hardened stainless steel, or copper alloy. The sliding surfaces between these types of spherical plain bearings could have hard chromium plating, PTFE composite, PTFE fabric, or PTFE plastic to reduce wear.

What is the method of mounting bearing?
Bearings with cylindrical bores are usually mounted by pressing them on the shafts (press fit) or heating them to expand their diameter (shrink fit). Bearings with tapered bores can be mounted directly on tapered shafts or cylindrical shafts using tapered sleeves.

Where plain bearings are used?
Plain bearings are used for sliding, rotating, oscillating or reciprocating motion. In sliding applications they serve as slide bearings, bearing strips and wear plates. In these applications the sliding surfaces are usually flat, but can also be cylindrical, and movement is always linear rather than rotating.
Where are spherical seated bearings used?
Spherical bearings are used in car suspensions, engines, driveshafts, heavy machinery, sewing machines, robotics and many other applications.
