ZYS Precision Bearing,Bearing Test Machine,Rolling mill bearing

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.

Tapered outer spherical ball bearings

Codename: UK200 series, UK300 series. Such spherical ball bearing bore ratio of 1:12 taper hole, used to be used in conjunction with the adapter sleeve, insert ball bearing such features as: affordable than with the top wire spherical ball bearings more load. Because of its tight fit with the inner diameter of the sleeve than the model with the top wire spherical ball bearings smaller, such as with an inner diameter of the top wire spherical ball bearings UC209 is 45mm, the diameter of its axis is compatible with the use of 45mm, and if if replaced with a tapered, spherical ball bearings, you can only choose an inner diameter of 45mm of tight sets, but not with 45mm adapter sleeve fit tapered, Ceramic Ball Bearings only UK210 (of course if the load higher, then you can choose UK310's). Thus, UK210 the load on when to make a much larger than the UC209 more.
