Mounting and dismounting

Cylindrical bore

Bearings with a cylindrical bore are easier to mount and dismount if they are of separable design rather than non-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 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.

Tapered bore

Bearings with a tapered bore (fig 2) can easily be mounted on a tapered journal or on a cylindrical shaft seat using an adapter or withdrawal sleeve (fig 3).
