Roller bearings and ball difference function

Roller bearings and roller ball bearings of the same points that they are high-vice campaign; all rolling bearings, has the characteristics of the performance of rolling bearings. The difference is that roller bearings deputy campaign and roller bearings are point contact and line contact. The use of roller bearings, printer manufacturers are still making trouble in the need for processing high precision coat, and need an experienced installer to find the right needle group. To solve this problem, manufacturers developed a bearing outer ring flange integrated roller bearings. Roller bearings can achieve good precision and rigidity through preloaded. And you can also use the inner tapered to arbitrarily adjust the bearing clearance. Such solutions can achieve zero printer roller bearing clearance requirements.
