NMB Miniature and Instrument Bearings
NHBB brand bearings, under the Minebea Mitsumi Inc. umbrella along with the NMB bearing brand, is a recognized leader in the design and manufacture of ultra-high-speed bearings which can operate at speeds up to 500,000 rpm. This capability is based on an unwavering commitment to superior bearing design, backed by cutting-edge bearing product development and a precision ball-bearing testing laboratory. The precision ball-bearing laboratory is dedicated to validating new bearing retainer materials. NMB brand and NHBB brand precision ball bearings, when considered to be ultra-high-speed, also need special consideration for bearing lubrication.
In addition to quality and properly selected bearing lubricant, ultra-high-speed bearings should include a machined retainer primarily from material that provides lubricity. For NMB brand bearings and NHBB brand ball-bearings to operate at ultra high speeds of more than 8,000 rpm, ball-bearing materials must be made from the best-bearing materials.
