FAG Sealed Spherical Roller Bearings With reliable protection against contamination
Spherical roller bearings are double row, self-retaining units comprising solid outer rings with a concave raceway, solid inner rings and barrel rollers with cages. The symmetrical barrel rollers orient themselves freely on the concave outer ring raceway. As a result, shaft flexing and misalignment of the bearing seats are compensated. Sealed spherical roller bearings are characterised by having sealing shields mounted on the external edge of both sides of the bearing. These protect against particles entering the bearing and act as a barrier against the lubricant leaving the bearing. Sealed spherical roller bearings offer many benefits for a wide range of applications:
longer operating life of the bearing
lower grease consumption and disposal costs
fewer expensive relubrication systems required
reduced maintenance outlay
Schaeffler’s reconditioning service is available for outside diameters 160 mm
environmentally friendly characteristics. They have the following properties:
very high basic dynamic and static load ratings
contact seal
bearing materials dimensionally stabilised up to +200 °C (S1)
two different sealing materials
angular adjustment facility 0,5° from the central position
standard dimensions in many cases; extra-wide bearings have a WS prefix
standard greases
limiting speed ng depending on the grease and grease fill level
X-life quality. Sealed spherical roller bearings are suitable for areas of operation such as continuous casting plant, conveyor belts, elevator plant or the food industry.
