629-ZZ Metric deep groove ball bearings

Metric deep groove ball bearings

Structure and Characteristics

A widely used bearing, the deep groove ball bearing takes its name from the formed on both the inner and ourer rings of the bearing. The bearings can sustain radial and axial loads and the resultant forces of these loads and they are suitable for high speed operation.

The dimensional table below represents the various cage models and special shapes.Drawing A is the pressed cage;drawing B shows the machined cage;drawings C through F show the position and shape of the notch on the inner ring;and drawing G shows a bearing with the key groove on the machined cages are used for larger sized bearings, or bearings for high speed rotation.

Except open bearings,most bearings manufactured by our company have shields or seals installed in both sides and are packed with a lubricant.Such bearings can simplify the structure around them and also their installation. It also eliminates the needs for relubricaton. Therefore, it reduces maintenance cost.Except open bearings,most bearings manufactured by our company have shields or seals installed in both sides and are packed with a lubricant.Such bearings can simplify the structure around them and also their installation.

Materials for cages
The materials for cages must have strength to withstand rotation at load and shock load. Low frictional efficiency light weight and be able to withstand operation temperature. The material used in ribbon cages or crown cages is 08F or SPCC pressed .It is chemical composition is shown for extra-high speed application. Plastic cages such as glass reinforced polymide are used. These plastic crown have the advantages of low torque, long grease lefe and low noise, etc.

Deep groove ball bearings, single rowBearings are used widely in all kinds of area,

such as Home Appliance(Air Conditioner,Washing Machine,Vacuum Cleaner, Hair Dryer, Fruit Mixer),

Power Tools, Automotive(Wiper Motor, Starter Motor, Power Steering System),

Office Applicance(Copier,Printer),Agriculture Machine.
