Cross roller bearings, because the inner or outer ring is split, and the interval after loading the roller cage, and Cross-Roller Ring secured together to prevent separation from each other, so when you install the Cross-Roller Ring Operation simple. Since the roller is staggered, so only one set of Cross-Roller Ring can withstand the loads in all directions, compared with the traditional model, rigidity increased by 3 to 4 times. Meanwhile, due to cross roller bearing inner or outer ring is constructed of two split, adjustable automotive bearing clearance, even if they are applied preload can be obtained with high precision rotary motion.
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.
