bearing measurement outer diameter, diameter size, height, which is the basic of the three dimensions was detected. Usually with a caliper and micrometer, or folders on the dial indicator gauge blocks, accurate point. With an inner diameter of the instrument can be beat and the outer diameter of the bearing runout. The main instruments for detecting bearing accuracy class enough.
Entity One way bearing GCr15 bearing steel, heat-treated hardness HRC61-65, bearing small size and high load carrying capacity, there is sufficient space to store the grease, may have come a long lubrication intervals.
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.
Nice! To ensure optimal slewing bearing performance, slewing bearing should always be stored flat, indoors, in low humidity and in original packaging.
