Rotating rings blanch the amount of interference to the
extent possible should also get smaller. As long as the operating
temperature and ensure the effect of thermal expansion, and the maximum Bearing manufacturing machine speed
of the centrifugal force, resulting in a tight fit so as not to creep
or sliding surfaces. Fixed ring size according to the work load and
bearing size, select small clearance fit or interference fit, too loose
or too tight is not conducive to maintaining the original shape
exactly.roller bearing measurement
ring on the shaft or housing rotation; overload large; bearing cage or
rolling fragmentation.1), the shaft and housing bore roundness and the
vertical shoulder block bearing according to the appropriate precision
requirements.2), it is necessary to accurately calculate the rotating
rings fit the amount of interference, but also suitable for accurate
calculation of the amount of the fixed ring.
Precision bearings according to ISO grading standards are divided into: P0, P6, P5, P4, P2. Rank higher in turn, where P0 is the general accuracy, other grades are precision level. Of course, different classification standards, different types of bearings, their classification method somewhat different, but the meaning is to the. The use of performance requirements of precision bearings rotating body with high runout accuracy, high-speed rotation and small changes in friction and friction.
