General Selection Factors
Several factors must be considered for choosing NMB bearings. These factors include the ring material, design, shields and seals, cage, Annual Bearing Engineering Committee (ABEC) grade, radial play, and lubricant. Miniature bearings are available in open, sealed and shielded configurations. Seals and shields are used in miniature bearings (specifically ball bearings) to retain lubricants and prevent particulate contamination from reaching critical surfaces. Seals are used where minimal light contact is offered. Seals for miniature bearings provide deterrence to particulate contamination, but increase torque and limit operating speeds. Shields are used in most applications.
