Ball bearing agent introduced its internal clearance and retainer ball bearing internal clearance: ball bearing internal clearance for service life, vibration, sound, fever and so on bearing performance have a significant impact.
Therefore, according to the purposes and select the appropriate internal clearance is very important.
Clearance can be divided into the radial clearance, axial clearance, clearance three clearance Angle.
Radial clearance is to make outer ring when inner ring fixed value when the moves in radius direction, the axial clearance is to make outer ring when inner ring fixed on the axial direction during movement, Angle windage is when inner ring fixed to outer ring tilt towards the direction of the axis when the mobile.
Ball bearing retainer: ball bearing cage can be divided into the following kinds: waveform cage (
R)
: with two steel plate stamping parts assembled, when assembling two folded into a ball shape, one of the parts are out of card card buckle will be another parts.
Crown retainer (
H)
: with a steel plate stamping parts processed into coronary.
Resin cage (
MN, etc. )
: made of resin material such as polyacetal cage, is helpful to increase service life and reduce noise.
