Load carrying capacity
In contrast to normal rolling bearings where the outer ring is supported over its whole circumference by the housing bore, load is applied to the indexing roller units via a small contact area on the outer ring cylindrical surface. Deformation of the outer ring leads to changes in the load distribution in the unit and the load carrying capacity is reduced. The basic load ratings given in the product table under the heading "Roller" take this influence into account.
With reference to the strength of the outer ring and the deformation produced in it, maximum permissible radial dynamic and static bearing loads are given in the product table in addition to the load ratings. The maximum static load which can be applied to the indexing roller is the smaller of the two values of F0r and C0.
