SKF has recently introduced a range
of slewing bearings. Unlike
traditional slewing bearings, SKF
slewing bearings can be easily utilized in
vertical bearing arrangements. This
additionally provides various design and
performance advantages. SKF Slewing
bearings are pre-lubricated with high
quality grease which reduces the risk of
pre-mature failure of machine along
with reduced maintenance cost with by
increasing lubrication intervals.
Lubrication intervals also help in
controlling lubrication wastage and
friction. SKF Slewing bearing offers best
results in multiple applications of wind
turbines, tunnel boring machines, solar
mirrors, railway bogies, small, medium
and large excavators, cranes, conveyor
booms, robots, etc.
SKF manufactures slewing bearings
in a number of types and variants such
as:
Single row crossed cylindrical
roller slewing bearings: These
slewing bearings are simple in design,
consisting of a one-piece inner and outer
ring and cylindrical rollers separated by
polyamide spacers and generally
protected by integral seals. SKF slewing
bearings are intended for bearing
arrangements where stiffness is
important or zero operational clearance
or preload as well as constant resistance
to rotation are required.
Double row ball slewing bearings:
These bearings are integrated with two
one-piece rings and two independent
rows of balls that offer greater stiffness
and accuracy to associated components
required for other types of slewing
bearings. The bearings are normally
preloaded and fitted with integral lip
seals.
Double row cylindrical roller
slewing bearings: Double row
cylindrical roller slewing bearings are
designed to accommodate heavy axial
and radial loads as well as high tilting
moments. Pre-integrated with lip seals,
it is particularly suitable for heavy-duty
applications.
