Mounting

a locating ring in position, make sure that the
open end of the locating ring is facing up.
CARB toroidal roller bearings, which are
used exclusively in the non-locating position,
require locating rings when the bearing seat
in the housing and the bearing width do not
match. For information about which locating
rings are required for a bearing in a particular
housing, refer to the relevant product chapter.

Installing seals
The seal counterface should meet the specifi-
cations for surface roughness and roundness
(† Specifications for shafts and housing sup-
port surfaces, page 45), and should be clean. If
the counterface shows any signs of wear, re-
pair it. This can be done easily with an SKF
SPEEDI-SLEEVE or a large diameter wear
sleeve (LDSLV). If repair is not possible, re-
place the shaft.
In general, the seal and counterface should
be coated lightly with the lubricant used in the
application.
When installing seals, make sure that the
seal is oriented correctly. Many seals are not
symmetrical and can be installed to either ex-
clude contaminants or retain the lubricant.
Split seals consist of two halves, which can
be installed around the shaft. They are easier
to replace and can ease mounting.
Felt seals should be soaked in hot oil prior
to installation.
