Mounting and dismounting
Bearings with a cylindrical bore are easier to mount and dismount if they are separable, particularly if interference fits are required for both rings. Separable bearings are also preferable if frequent mounting and dismounting are required, because the ring with the rolling element and cage assembly of these separable bearings can be fitted independently of the other ring, e.g. four-point contact ball bearings, cylindrical, needle and tapered roller bearings (fig. 1), as well as ball and roller thrust bearings.
