637 Bearing
637 Bearing which is Metric Size Miniature Ball Bearings have deep groove geometry for high speeds and supporting both radial and axial loads. These 637 Metric Size Miniature Ball Bearings are for use in applications that involve combined radial and axial loads and a need for high running accuracy at high rotational speeds. For instance, 637 is often used in motors, ATMs as well as Card Readers. In Food & Beverage Industry, 637 is also popular. More applications about 637 are as follows.
Typical applications include:
Motors,Flow Meters,Medical Instruments,Vacuum Pumps,Robotics Industry,Crossbow,Food & Beverage Industry,Automation & Industry,Anemometer,ATMs & Card Readers,Galvanometers,Gas Meters,Industrial Encoders,Industrial Meters,Optical Encoders,Plastic Card Printers,Surveillance Systems,Fuel controls,Gyros, synchros and servos,Cryogenic coolers,Pulmonary assist devices,Clocks,Instrumentation,Drones and model,Fishing reel
General Selection Factors
Several factors must be considered for choosing miniature ball 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. Close
