INA Bearing Insert 25 mm ID 57.3 mm OD RCRB25/57-XL-FA106

INA from Schaeffler radial insert ball bearings with rubber interliners are on the shaft using an eccentric locking collar. The outer ring is encased in a thick-walled NBR interliner which absorbs vibrations and shocks. The interliners have either a spherical or cylindrical outside surface.;The P seal is two zinc-coated sheet steel washers with intermediate NBR part, seal lip axially preloaded.;To protect the seal lip from mechanical damage, the outer sheet steel washer extends a considerable distance down towards the bearing inner ring.;Used in narrow radial insert ball bearings with inner ring extended on one side.

• Lower operating costs;• Reduced maintenance due to improved lubrication;• Lower heat generation;• Less noise;• Inner ring and locking collar have anti-corrosion protection;• Shaft diameters from 12 mm to 50 mm (RABRB);• Shaft diameters 20 mm (RCRA) 25 mm (RCRB) ;• Shaft diameters 30 mm (RCSMA) 15 mm to 25 mm (RCSMB)

Bearings with rubber interliners cannot be lubricated.
