Precision Mechanical Bearing Assemblies

From design conception to delivery, NMB’s mechanical bearing assemblies are high precision custom products, manufactured to the highest standards of quality, cost effectiveness and reliability. NMB’s miniature precision ball bearings are the first component of a highly successful design for a mechanical bearing assembly. Machined components such as magnets, gears, molded and machined plastic parts, die cast parts and special materials are designed and manufactured to work precisely with NMB precision ball bearings. Our assembly process and inspection methods have been optimized to produce the highest quality product for your application.

Tape Guides

Tape Guides are manufactured using high precision NMB miniature ball bearings as well as non-magnetic materials such as aluminum, SUS 303 stainless steel, and a large availability of different types of resin materials.  Metallic tape guides can also be hard plated with non-magnetic electro less nickel plating as well as other special hard coating.

  • Magnetic tape devices in audio and video equipment
  • Data recorders


Custom Pulleys

Custom pulleys integrate NMB’s precision miniature bearings into a custom made design to your specifications.  The precision bearings are press fitted, bonded or over-molded to produce the pulley. Pulleys can be developed and manufactured with grooves, gears, rubber, and shafts, and are designed to increase the accuracy of your application.
