How is bearing accuracy differentiated? Bearing tolerance clas

Level0: generaly used for bearing system with rotationl accuracy exceeding 10 microns, the application is very common.. For example, the ordinary CNC lathe on the speed mechanism, go knife mechanism, go knife mechanism, car speed mechanism, large tractor speed mechanism, ordinary chemical machinery such as motors, centrifugal pumps and agricultural machinery rotating mechanism.

Level 6: grade 5: in the rotary accuracy of 5-10 microns or high speed precision bearing systems such as CNC lathes commonly used bearings( from support point level 5, rear support point level 6), the finer instruments, panels and their insturments, instrument panels and precision rotating machanism.

Level 4, level 2, in the ultra-instrumentation, such as fine coordinates milling machine, fine grinding machine drive gear system software, such as instrumentation, instruments panels and high-speed cameras, etc, the rotational accuracy of not more than 5 microns, the rotational speed is relatively high, China bearings before the old code precision grade code.

Internationally formulated specifications are in accordance with ISO standards, are generally unifed with ISO, some are more stringent.

Accuracy is divided into specification accuracy and rotational accuracy, Divided into 0 degrees, 6X degrees, 6 degrees, 5 degrees, 4 degrees, 2 degrees,

In china before the bearing code regulation are : G level( 0), E level(6), D level(5), C level(4), B level(2). The current standard code generally adopts the German DIN speciation.

(a) P0 (0), P6 (6), P5(5), P4(4), P2(2) grade(2), Ordinary specification grade P0, reflected in the bearing type specification is omitted, only P6 or P6 or more grades, grade code appears in the bearing types specification.

For example, 6205 and 6205/P5, of which 6205 accuracy level P0, just omitted, this gives you an introduction, P0 grade is the image of non-non-accuracy grade bearings.

In addition, all kinds of precision bearigns are separated differently in the process, and they are different in the use value, For example, the use value of CHina's HRB bearings, the accuracy of P6 1.5times, P5 2times, P4 2times, P5 2times, P5 2.5times, P5 2.5times.
