Bearings #1387660

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.

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 loadsreversing and non-reversingor continuous oscillation.

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.

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.

Custom rod end bearings from NHBB are the choice of engineers dealing with unique geometries and dimensional constraints. NHBB customizes rod ends to hold heavier loads, operate at temperature extremes, provide stronger fatigue resistance and meet requirements for angular misalignment. We also offer ball bearing rod ends for low friction, low backlash applications. For both custom and standard applications, we understand the importance of choosing materials to match your operating environment. Our stainless steel cadmium-free rod ends are the industrys first to meet ACBG standards AS819356, 7, 8 and 9, offering equivalent dimensions and performance to cadmium-plated rod ends without the potential risks and regulatory burdensincluding European Union environmental regulationsassociated with cadmium. Our rod end bearings come in either metal-to-metal or self-lubricating PTFE-lined versions. Metals include cadmium-free stainless steel, titanium, Inconel 718 (a nickel-chromium based super-alloy for high-temperature applications), and Stellite (cobalt and nickel-based alloys).

Spherical bearings from NHBB address the unique operating parameters faced by engineers in the aerospace, defense, and other high technology industries. We customize bearings to work outside the standard spectrum of load, temperature, fatigue resistance, and angular misalignment. Our Astro Division developed the first liner system for spherical bearings that qualifies to the threshold of 100, 000 cycles for bearing life (industry standard AS81820 Type 'A'). Our customized and standard bearings also include swaged, split ball, spit race, fracture race, snap assembled, and loader slot. NHBB understands the importance of choosing materials to match your operating environment. We design bearings using cadmium-free stainless steel, titanium, Inconel 718 (a nickel-chromium based super-alloy for high-temperature applications), and Stellite (cobalt and nickel-based alloy), in both metal-to-metal and self-lubricating PTFE-lined versions.

This product line encompasses inch and metric series radial and angular contact ball bearings from 0.1250 in. to 1.8504 in. O.D. Optional features include flanges, shields and seals, extended inner rings, and modified dimensions. Duplex and super duplex constructions are also available. Our high speed angular contact bearings operate comfortably at speeds above 500, 000 rpm. Many alternatives exist for improving high speed performance and operating life, including premium bearing steels, ceramic balls, proprietary lubricants, and machined cages made from phenolic and Torlon .

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.

NHBB and myonic have joined together as Minebea subsidiaries to offer the industrys widest selection of high quality dental bearings and assemblies. By combining not only our product offering but also our knowledge of and experience with the dental industry, our precision manufacturing practices, and our R&D efforts, NHBB and myonic are creating a new platform for delivering the best performing and longest lasting bearings available in the marketplace today. Smooth, quiet and fully autoclavable, our full line of radial and angular contact dental bearings feature premium steels, tight dimension control and superior surface finishes. Design options include ceramic balls, proprietary lubricants, integral- and reduce-clearance shields, and machined retainers made from phenolic and Torlon.

NHBBs precision, hybrid ceramic ball bearings are an excellent choice for high speed applications. A ceramic (silicon nitride) ball weighs less than a steel ball, is stiffer, and has a near-perfect geometry and superior surface finish. These properties enable a bearing to operate at higher speeds and reduced temperatures with less wear. Noise and vibration levels are also kept to a minimum. Furthermore, ceramic balls are corrosion resistant, nonmagnetic, and able to withstand repeated autoclaving, which makes hybrid ceramic ball bearings a good choice for medical and dental applications.
