china manufacture cheap deep groove ball bearing 6203 6203zz 6203 2rs

Standard with a ring of deep groove ball bearings with contact seals bearing RS-type (side seal), 2RS type (seal on both sides) and non-contact sealed bearings RZ-type (side seal), 2RZ type (seal on both sides).


With a ring of bearing performance, add butter and use with a dust cover bearing is basically the same.
Is a large gap between the dust cover and the inner ring of the bearing with dust cover, a small gap between the sealing lip and the inner ring instead of the contact ring bearing, contact seals bearing the seal lip there is no gap between the inner and good sealing effect, but friction increase.

Low noise requirements of the occasion, the use of the 60 and 62 series of smaller size deep groove ball bearings.

Whether open bearings with dust cover type or with a ring-type bearings, low noise, low vibration can be raised in order requirements.

In our JB (mechanical industry standards) provides V1, V2, V3 vibration levels of low, medium and high frequency band vibration allowable value.
