Lock nuts
SKF lock nuts, also referred to as shaft
nuts, are available in several designs
to axially locate bearings on shaft
ends. The most popular are those of
series KM, KML and HM. These nuts
have four or eight equally spaced slots
in the outside diameter and are locked
in position with locking washers or
locking clips engaging a groove in the
shaft. The nut dimensions are in accordance
with ISO 2982-2:1995 as
are the dimensions of the series MB
and MBL locking washers and MS
locking clips.
Other lock nuts produced by SKF
include those of series KMT, KMTA,
KMK and KMFE, that do not require
a groove in the shaft.
Lubricating greases for bearings
Lubrication is a necessity for proper
bearing performance. Grease is normally
used for applications involving
SNL plummer blocks. SKF has put
considerable effort into establishing
a range of high-quality greases for
ball and roller bearing lubrication.
The SKF SYSTEM 24 automatic
lubricator can also be used with SNL
plummer block housings. An adapter
can be fitted to the standard drilled
and tapped hole in the housing cap.
It should be remembered that surplus
grease should be able to leave the
housing.
SKF ConCentra roller bearing units
These units are plummer blocks with
ready-lubricated bearings for easy
installation. They comprise
• a one-piece plummer block housing
of grey cast iron,
• a spherical roller bearing of series
222 with special inner ring,
• a special adapter sleeve, and
• two seals of nitrile rubber double lip
type or two labyrinth seals.
The units are available in a locating
and a non-locating version.
