Product description of FAG Bearing 222S.507-MA

FAG Bearing 222S.507-MA, it belongs to FAG Bearing > Rolling and Plain Bearings > Roller Bearings > Spherical Roller Bearings,Spherical roller bearings are very similar to cylindrical bearings with one exception in that the rollers are rounded around their midsection.

FAG Bearing 222S.507-MA, Spherical Roller Bearings with hardened steel cages deliver greater fatigue strength, increased wear-resistance and tougher protection against shock and acceleration.Spherical Roller Bearings with brass cages provide extra strength and durability in the most unrelenting conditions, including extreme shock and vibration, high acceleration forces and minimal lubrication.

The outstanding feature of all spherical roller bearings is angular adjust-ability. This is achieved with a double row rolling element set based on symmetrical barrel rollers, which orient themselves freely on the mutually curved raceway in the outer ring and the two raceways inclined relative to the bearing axis in the inner ring.

In addition to standard spherical roller bearings (without seals, with a tapered or cylindrical bore), specialized designs are available for special requirements: spherical roller bearings for vibratory machinery split spherical roller bearings for simplified bearing replacement sealed spherical roller bearings.

FAG Bearing 222S.507-MA, Spherical roller bearings are suitable where: • bearing arrangements are subjected to high and very high radial loads • relatively high axial loads occur on one or both sides, in addition to high radial forces • dynamic or static misalignment of the shaft relative to the housing, or deflections of the shaft, must be freely compensated by the bearing • high shock type loads must be supported dynamically • locating bearings with a very high load carrying capacity are required Spherical roller bearing: comparison of load carrying capacity with barrel roller bearing of the same dimensions, compensation of misalignment Fr = radial load Cr = basic dynamic load rating

FAG Bearing 222S.507-MA, Bearings of basic design

The outer ring has a curved raceway

Spherical roller bearings are part of the group of radial roller bearings. These self-retaining rolling bearings have two rows of rollers with a mutually curved raceway in the outer ring and two raceways inclined relative to the bearing axis in the inner ring. This raceway design allows these bearings to combine a range of characteristics, which are essential to many applications, in one bearing, such as angular adjust-ability for example, The symmetrical barrel rollers are guided by brass, sheet steel or poly-amide cages

Roller contact design

The stress distribution at the contact points between the rollers and raceways is determined by the contact surface of the rollers. As a result, the roller geometry is matched to the raceway. This gives a favourable load distribution over the entire length of the roller and prevents both edge stresses and stress peaks at the ends of the roller

Spherical roller bearings for vibratory machinery

The rolling bearings fitted in vibratory machinery must support not only high loads and high speeds but also accelerations and centrifugal forces. In many cases, these applications involve adverse environmental conditions such as contamination and moisture.

FAG Bearing 222S.507-MA, Spherical roller bearings are matched to the operating conditions of vibratory machinery

The special spherical roller bearings developed by Schaeffler are matched to the operating conditions in vibratory machinery and have proved highly successful in practical use. In particular, the cages of the rolling bearings are subjected to stresses arising from high radial accelerations. In unfavourable cases, these may be overlaid by axial accelerations as well.

The support of angular misalignment reduces additional sliding motions

The rotating imbalance generates a rotating shaft deflection and additional sliding motion within the bearings. This increases the friction and therefore the operating temperature of the bearings. The special spherical roller bearings can support dynamic angular adjustments up to 0,15°.

Basic designs of special spherical roller bearings

Schaeffler special spherical roller bearings for vibratory machinery have the main dimensions of dimension series 23 (DIN 616:2000, ISO 15:2017).

Specification T41A (T41D)

Schaeffler spherical roller bearings for vibratory machinery are manufactured in accordance with the specification T41A or T41D, This takes into consideration the particular requirements of the application. The specification defines, for example, the tolerances of the bore and outside diameter, as well as the radial internal clearance of the bearings. The other tolerances are in accordance with tolerance class Normal to ISO 492:2014.
