3209-BD-XL-C3 BALL BRG

• Solid inner and outer rings and ball and cage assemblies with polyamide or sheet steel cages • Construction is similar to a pair of single row angular contact ball bearings in an O arrangement but they are narrower to a certain extent • Available in open and sealed designs • Due to the manufacturing processes used, open bearings can have turned recesses in the outer ring for seals or shields • Sealed bearings are maintenance-free and therefore allow particularly economical bearing arrangements • Due to the raceway geometry and the two rows of balls, the bearing can support forces in both radial and axial directions and are therefore particularly suitable for use in pumps and agricultural machinery • Used in applications including conveying equipment, packaging equipment, elevators and compressors • The angular adjustment facility of angular contact ball bearings is very limited and, therefore the adjustment angle should not exceed two • Bearings of X-life quality have improved running accuracy and optimized surfaces which gives a significant increase in the fatigue limit load of the bearings • In terms of the expanded adjusted rating life, values up to 50% are achieved • In certain applications, this means that a smaller bearing arrangement can be designed • Lower noise levels, reduced friction, improved sealing and higher cost-effectiveness • Standard cages are made from sheet steel, and are suitable for temperatures up to +200° C • More rigid and thus more robust and generate less operating noise
