This bearing is from the brakes section in the Rolls-Royce & Bentley parts catalogue for models built between 1956 to 1965.
This bearing is located on the first arm of the brake servo. The Servo is a complicated system that uses the rotary motion of the propshaft to actuate the master cylinders. To work properly it must be set up accurately.
