take into account the best use of turbocharger bearings and ball screw bars on rigid balancing, high rigidity and low torque of angular contact ball bearings (contact angle of 30 °, free combination). Meanwhile, the ultra-compact support unit EK6,8 equipped with ultra-small ball screw bars for the development of the ultra-compact angular contact ball bearings. This bearing contact angle is 45 °, ball diameter is small, the number of balls and more, with a high rigidity, high-precision ultra-compact angular contact ball bearings, slewing can get a stable performance.
(2) the shape of the support unit and support unit has angle-round series, can be selected according to the application.
(3) small in size and easy installation of the support unit is considered around the mounting space, the design of a small volume. Meanwhile, adjusted pre-loaded pressure Dental bearing assembly can be directly after delivery, not only reduces the assembly work, but also improve the accuracy of the assembly
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.
