The double groove guide bearings are suitable for all kinds of industrial equipment, small rotary motor, office equipment, micro motor soft driver, pressure rotor, dental drill, hard disk motor, stepping motor, recorder drum, toy model, fan, pulley, roller, transmission equipment, entertainment equipment, robot, medical equipment and office equipment. Testing instruments, deceleration, transmission, motor optics, imaging equipment, card reader, electromechanical, precision machinery, electric tools and toys.
The application is so extensive that both the manufacturer and the user will be concerned about the long life of the flange bearing, such as: the double groove guide bearing is mainly subjected to radial load, and can also bear radial and axial loads at the same time. But the life of flange bearings is not very well understood. Here are 3 measures to extend the bearing life.
(1) in order to make the clearance between the bearing retainer and the bearing ring larger than the eccentricity, the internal structure is improved.
(2) use FEM analysis to optimize the shape and thickness of the plate to improve the retainer strength.
(3) to prevent surface damage caused by the reduction of lubricating oil, guide grooves are designed in the bearing ring.
