What is spherical roller bearing?
Spherical roller bearing is rolling-element bearing that permits rotation with low friction, and permits angular misalignment. Typically these bearings support a rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring. The misalignment is possible due to the spherical internal shape of the outer ring and spherical rollers. Despite what their name may imply, spherical roller bearings are not truly spherical in shape. The rolling elements of spherical roller bearings are mainly cylindrical in shape, but have a (barrel like) profile that makes them appear like cylinders that have been slightly over-inflated. 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.
How do you check spherical roller bearing clearance?
The measuring method of feeler gauge is the main method to detect the spherical roller bearing clearance with adjustable center. The method is simple and efficient. However, since the limit gauge method is adopted, the definite value of clearance cannot be determined.
What is a spherical roller bearing used for?
Spherical roller bearings are used in car suspensions, engines, driveshafts, heavy machinery, sewing machines, robotics and many other applications. Spherical roller bearings Widely used in papermaking machinery, deceleration devices, railway vehicle axles, rolling mill gear box bearing housings, rolling mill rollers, crushers, vibrating screens, printing machinery, woodworking machinery, various types of industrial reducers, vertical self-aligning bearings with seats. Spherical bearings are used in countless industrial applications, where there are heavy loads, moderate speeds and possibly misalignment. Some common application areas are: Gearboxes, Wind turbines, Continuous casting machines, Material handling, Pumps, Mechanical fans and blowers, Mining and construction equipment, Pulp and paper processing equipment, Marine propulsion and offshore drilling, Off-road vehicles.
What are the features of Spherical roller bearing?
Spherical roller bearings can be divided into the following types according to their design and characteristics: sealed spherical roller bearings, CA-type spherical roller bearings, E-type spherical roller bearings, CC-type spherical roller bearings, MB Type Spherical Roller Bearings, MA Type Spherical Roller Bearings, Single Row Spherical Roller Bearings and E1 Type Spherical Roller Bearings. Most spherical roller bearings are designed with two rows of rollers, allowing them to withstand very heavy radial loads and heavy axial loads. There is also a design with a row of rollers, which is suitable for lower radial loads and almost no axial loads. These are also called "roller bearings" or "Tonnenlager", and are usually available in the 202 and 203 series. The internal design of the bearing is not standardized by ISO, so it differs between different manufacturers and different series. Some features that may or may not be present in different bearings are: Lubrication features in inner or outer ring, Central flange, Guide ring or center ring, Integrated seals and Cage.
