Mounting

During handling, the rings and roller complement of spherical roller bearings may be axially displaced from their normal position. This is especially likely where the bearings are mounted with the shaft or housing in the vertical position:

The roller complement, together with the inner or outer ring, will move downward and result in no more clearance.

When the bearing rings expand or contract as a result of an interference fit, preload is likely to result.

Therefore, wherever possible:

Mount spherical roller bearings with the shaft or housing in the horizontal position.

Rotate the inner or outer ring to align the rollers during mounting.

Where this is not feasible, use a bearing handling tool or other device to keep the bearing components arranged centrally.

The assortment of spherical roller bearings is the widest available on the market. The standard assortment includes:

CC, CA and E design bearings

sealed bearings

bearings for vibratory applications

bearings for wind energy applications

All spherical roller bearings are SKF Explorer bearings and almost all bearings are available with the option of a tapered bore. Depending on the bearing series, the tapered bore has:

a taper 1:12 (designation suffix K)

a taper 1:30 (designation suffix K30)
