R Series Flange deep groove ball bearing

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.

Vibration and noise

● The measuring parameter of vibration adopted by RNB is the vibration acceleration of vibration velocity.

● The measuring units and measuring method are specified by JB/T5314 and JB/T5313
      In the process of measuring vibration strictly controlled noise by using acoustics.
