SMB miniature and instrument ball bearings are used extensively in many areas of control, instrumentation and metrology including laboratory instruments, flow instruments, rotary encoders, stepping motors, servo motors, weighing devices and disc drives. Our instrument bearings are available to fit shaft sizes as small as 0.6mm or 0.04 inches.

The stainless steel versions are widely used in outdoor meteorological instruments, marine navigation systems or medical instruments. Our miniature bearings relubricated with dampening greases can be used in potentiometers in dials and controls or in positioning devices for a more precise, quality feel.

Optical instruments such as cameras and microscopes often use precision, low friction thin section bearings. Cameras may use miniature bearings in gimbals and slide mechanisms. CCTV cameras use miniature or thin section bearings in positioning motors and mechanisms while microscopes often use thin section bearings in focusing systems, nosepieces (turrets) and boom stands.

Many instrument applications require low friction bearings. Sapporo Precision’s EZO brand bearings are low friction bearings due to excellent standards of roundness and surface finish but they also use a low torque grease as standard in miniature and thin section bearings. Our bearing processing facility allows us to provide fast delivery of bearings with lubricants such as ultra light instrument oils or very low torque greases. Low friction non-contact seals are available on some sizes.
