NHBB manufactures standard and custom designed ball bearing solutions for a myriad of aerospace, defense, dental, high tech, and medical applications. Our product lines feature inch and metric series ball bearings ranging in size from 0.1250 in. to 11 in. O.D.
The following product families are described below: miniature & instrument ball bearings , dental bearings, hybrid ceramic bearings, large aerospace ball bearings, and torque tube & thin section (Thinex) ball bearings.
Miniature & Instrument Bearings
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 ®.

Hybrid Ceramic Bearings
If you want to extend bearing operational life, especially under conditions of marginal lubrication, consider specifying NHBB’s hybrid ceramic ball bearings.
NHBB’s 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.
Did you know it’s possible to enhance corrosion resistance of a hybrid ceramic ball bearing by using ceramic balls in combination with a dry film lubricant on the ring and retainer components? Learn more about dry film lubricants.

Large Ball Bearings for Aerospace Applications
Our 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.

Thin Section (Thinex) & Torque Tube Bearings
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.
