Design of stainless steel deep groove ball bearings

    Bearing with dust cover
    The bearing with dust cover is suffixed with 2Z and the dust cover is made of stainless steel. The shoulders of the inner cover of the dust cover form a very narrow gap and can withstand high temperatures and high rotational speeds. Bearings with dust caps are mainly used in the rotating condition of the inner ring. If the outer ring rotates, the bearing will run at high speed, which will cause grease to leak.
   
    Bearing with seal
    Bearings with contact seals, suffixed 2RS1, are made of oil-resistant and wear-resistant nitrile rubber with a steel frame. This allows the seal to operate at temperatures from -40 to +100 ° C and up to +120 ° C in a short time. The sealing lip of the contact seal seals the shoulder of the inner ring. The groove on the outer ring of the outer ring of the seal ring provides a good sealing effect at this position.

    When the sealed bearing is operated under certain extreme conditions, such as extremely high speed or high temperature, it may cause leakage of grease between the inner ring and the seal. If the leak condition has a damaging effect on the bearing configuration, special design steps must be taken.

What are the ways to control the influence of bearing noise?

     Generally speaking, in order to control the noise influence of the rolling bearing, it is necessary to take countermeasures against the root cause of these noises in order to receive the effect of the root cause. The main route is:

(1) Select low noise bearings;

(2) Try to eliminate noise from the application of the bearing,

(3) Avoid resonance with the host and avoid resonance sensitive speed;

(4) When other methods are ineffective, take additional measures for sound insulation and noise reduction.
