What is flange bearing?

Flange bearings from printers and fax machines to monitors, there is room for flange bearing products to show their technology in household items used in daily life. Under the standard ABEC-1 level of size and precision requirements, the bearings are produced to meet the general purpose products.

What are the advantages of flange bearings?

The series of products with flanges on the outer wheel make the axial positioning easy; the housing is no longer needed and becomes more economical. In order to obtain low friction torque, high rigidity, and good rotary accuracy of the bearings, small outer diameter steel balls are used. The use of hollow shaft ensures light weight and space for wiring

What are the features of flange bearings?

The most important feature is the integration of the flange with the bearing. When there is no connection at one end of the shaft and it needs to be fixed to a flat surface such as a plate or wall, the flange bearing shows its advantages.
Among the miniature bearings with ultra-small bore, they can be divided into ZZ steel plate bearing dust cover series, RS rubber bearing seal series, Teflon bearing seal series, flange series, stainless steel series, ceramic ball series, etc. Miniature ball bearings have a wide range of applications. Suitable for high speed rotation, low friction torque, low vibration and low noise requirements.

What are the uses of flange bearings?

Flange bearings are suitable for all kinds of industrial equipment, small rotary motors, office equipment, micro-motor soft drive, pressure rotor, dental dental drill, hard disk motor, stepping motor, VCR drum, toy model, fan, pulley, roller, transmission equipment, entertainment equipment, robot, medical equipment, office equipment, testing instruments, speed reduction, variable speed device, motor optical, imaging equipment, card reader, electromechanical, precision machinery, power tools and toys, etc. precision machinery, power tools and toys, etc.

How to extend the service life of flange bearings?

(1) in order to be able to make the bearing retainer and bearing ring between the radius direction of the clearance set than the eccentric amount, the internal structure is improved.
(2) The strength of the retainer is improved by optimizing the shape, plate thickness, etc.
(3) A guide groove was designed in the bearing ring to prevent surface damage caused by reduced lubricating oil.
