The FAG B7011-E-T-P4S-DUL is a high-precision spindle bearing from INA-FAG (Schaeffler), designed for demanding applications requiring high accuracy and speed. Featuring a 55mm bore diameter, 80mm outer diameter, and 13mm width, this bearing has an optimized internal design (E) with a 25° contact angle. It utilizes a textile laminate phenolic resin cage (T) and belongs to the P4S tolerance class, ensuring superior running accuracy. The universal design (DU) allows for paired mounting, and it comes with a light preload (L) for optimal performance. With limiting speeds of 24000 1/min for grease lubrication and 38000 1/min for oil-air lubrication, it is ideal for machine tool spindles and other high-speed rotating equipment.
