2.Application:

 Miniature bearings are suitable for all kinds of industrial equipment, small rotary motor in high speed low noise field, such as:

Office equipment, micro motor, instrument, skateboard laser engraving, small clocks, soft drive, pressure rotor, dental drill, drive motor, stepping motor, VCR drum, toys, computer cooling fan, currency counting machine, fax machines and related fields.

3.The method  of bearing installation:

(1) cleaning bearings and related components;

(2) Check the connected components of size and finishing machining;
(3) Installation
(4) inspection of the bearings after installed;
(5) the supply of lubricant. 

4.Working Principle :

Deep groove ball bearings mainly take radial load as well as both radial and axial load. When only radial load, the contact angle is zero. When deep groove ball bearings with radial clearance with the performance of angular contact bearings, can withstand large axial load, deep groove ball bearings, the friction coefficient is small, the speed is also high.

5.Service life :

Motor bearing life is one year etc.

6.Note:

Deep groove ball bearings, bearing load operation is too small, sliding between the ball and the raceway will become the cause abrasions. Is this tendency of the weight of the ball and cage large deep groove ball bearings
