NHBB

This group features bearings with thin rings, narrow cross sections, large bore diameters, and a large number of small diameter balls. They are used when bearing size and weight need to be kept to a minimum and when high accuracy, high stiffness (less deflection), and low friction are required. We manufacture radial, angular contact, and gothic arch versions in sizes ranging from 0.75 in. to 11.00 in. O.D. As always, custom solutions are available.

large diameter precision ball bearings are engineered to perform in life-critical commercial and military aircraft applications. The line includes radial, angular contact, gothic arch, and fractured race construction types in sizes up to 11.024 in. O.D. Our customized solutions feature elements that satisfy a multitude of mounting and operating requirements. Options include special alloys, case hardened rings, extended housings, integral flanges, puller grooves, anti-rotation notches, oil scavenge holes, and more. Duplex and super duplex configurations are also available.

sleeve bearings are made for both static and dynamic conditions. Lubricated bearings can be made from bronze, steel or stainless steel, with or without lube grooves and holes. Self-lubrication is recommended for any application in which dynamic conditions require the capability to handle heavy loads–reversing and non-reversing–or continuous oscillation.

Loader slot bearings are generally recommended for applications with vibratory or static loads which produce small relative motion between the ball and race. Loader slots possess excellent ball-to-race conformity, which increases resistance to damage from vibration. When wear does occur, the ball can be replaced without removing the bearing assembly from the housing, which reduces downtime and lowers maintenance costs. NHBB manufactures spherical loader slot bearings in sizes ranging from 0.5625 in. to 3.625 in. O.D. and two-piece rod end loader slots with head diameters from 0.680 in. to 2.681 in. O.D. Standard features include fully interchangeable Stellite® balls and Nitride (or Malcomize) spherical race I.D.s. Rod ends have male threads; keyways are optional.

Designed for reliable performance, our full line of Airframe Control Bearings are manufactured and inspected in accordance with Aerospace Standards AS7949. They possess a low coefficient of friction and low torque, which are suitable performance factors for applications with oscillating motion or slow intermittent rotation. Precision construction assures excellent radial and axial positioning. SAE 52100 chrome steel with cadmium plating is standard; 440C stainless steel is also available. Unless otherwise specified, these bearings have a full ball complement design.
