Features & Benefits
SPHERE-ROL bearings are available in two standard series:
22200 series, 20mm to 150mm bore sizes
22300 series, 40mm to 100mm bore sizes
SPHERE-ROL bearings are a sealed spherical roller bearing series. They are dimensionally interchangeable with conventional double row spherical roller bearings.
A single row of large rollers results in increased dynamic load capacity. It also results in up to 100% greater misalignment of conventional double-row spherical roller bearings.
Potential extended bearing life as a result of three different sealing options available:
NYLAPLATE seal: Combination labyrinth / contact seal with low running friction
NYLAPLATE high temp seal: High temperature material combination labyrinth / contact seal for high temperature applications or where chemicals may be present
LAMBDA® seal
Sealing features of NYLAPLATE bearing seals are combined with the lip-wiping sealing function of an added contact seal. This is for applications where contamination conditions are particularly severe. It is also for where substantial amounts of moisture are present.
Available with cylindrical bore or tapered bore.
Spherical Roller Bearings Information
Show all Spherical Roller Bearings Manufacturers
spherical roller bearings imageSpherical roller bearings utilize two rows of friction-reducing, barrel-shaped rollers located between an outer ring with a spherical raceway and an inner ring composed of two inclined raceways. These bearings are valued for their ability to compensate for misalignment and shock loads due to their raceway geometries, and are used in many heavy-duty industrial applications.
Operation
The unique design of the roller raceways is the most distinguishable feature of a spherical roller bearing. The inner part of the outer raceway is manufactured with a concave depression, and the outer part of the inner raceway is provided a convex protrusion. Two rows of barrel-shaped rollers are held together by a cage or cages in a fashion which complements the shape of these roller raceways. The result is a bearing with exceptional radial capacity, which can also accommodate axial loads, misalignment, or shock since the bearings are constantly reorienting themselves against the spherical raceway of the outer ring. Unlike many other types of bearings, spherical roller bearings cannot be disassembled.
This type of bearing can be mounted individually but is also commonly installed in identical pairs for shaft and axle support, with one of the bearings axially fixed, and the other mounted with a loose fit so it can float along the shaft. If the inner ring rotates it should be installed with an interference fit, since loose-fit installations can result in bearing creep, shaft wear, and an increased chance of environmental debris interference. Rotating outer rings should also utilize an interference fit between the outer ring and the housing for similar reasons. Stationary outer rings benefit from a loose fit to permit assembly and axial movement, while stationary inner rings are dependent upon the load and specifications of the application.
