Nachi Radial Ball Bearing 6911 Open 55mm Bore 80mm Od 6911

NACHI Radial Ball Bearing 6911, Open, 55MM Bore, 80MM OD

Radial Ball Bearing has moderate load-carrying capacity in both radial and axial directions and is good for high speed and high accuracy. Rubber seal or metal shield on one or both sides of the bearing helps keep out dirt and contaminants. In case two seals or two shields are used, the bearing is lubricated by grease for its life when manufactured. The bearing with 10 to 75 mm bore (6000 to 6300 series) & 10 to 50 (6800 & 6900 series) improves reliability with newly designed seal and shield, and suitable grease. Quiet rotation is expected by improved accuracy of components, and saving cost and energy is also expected by lower power loss provided by low and stable running torque.
