SMF41x miniature ball bearing has deep groove geometry for high speeds and supporting both radial and axial loads. SMF41x bore dia is 1.2 mm. Its out dia is 4 mm. SMF41x ball material is 440C Stainless Steel. Its seal type is Open. This SMF41x miniature bearing is for use in applications that involve combined radial and axial loads and a need for high running accuracy at high rotational speeds. 

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, etc.

General Selection Factors

Several factors must be cons956ered 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 prov956e deterrence to particulate contamination, but increase torque and limit operating speeds. Shields are used in most applications.
