SKF, the leading knowledge
engineering company, has launched its latest generation of SKF
ConCentra roller bearing units, which can be mounted 20 minutes
faster than conventional split housings, saving costs both
initially in mounting and later in maintenance. Additionally, the
units enable more accurate mounting, resulting in high bearing
performance and longer bearing life. Subsequently, this contributes
to improved performance in manufacturing machinery and ancillary
equipment.
The latest units use SKF's unique locking technology to
facilitate mounting and dismounting. Once the unit is on the shaft,
it is locked in position in a couple of minutes by tightening three
screws to a pre-determined torque, using the 'smart' Allen key
provided. This method ensures the bearing is locked 100%
concentrically around the shaft, improving bearing and machine
performance, and making dismounting quick and easy.
The SKF ConCentra units are pre-lubricated, which reduces
premature bearing failure due to over-greasing or the ingress of
contaminated grease into the bearing during maintenance. There are
four variations available, which have a specially selected grease
and seal for the 'typical' application condition: general, for
normal applications concerning speed and cleanliness; high speed,
for high rotational speeds; rugged, for extremely dirty operating
conditions; and endurer, which is completely lubrication-free under
certain conditions.
The unique design of the latest units offers a range of
additional benefits in industrial applications. For example, shaft
damage is eliminated, as 100% concentricity means that mounting the
unit does not damage the shaft. Misalignment and shaft expansion
can be accommodated, as all sizes have self-aligning SKF Explorer
spherical roller bearings. The units also contribute to energy,
cost and environmental savings, and are manufactured to ISO
standards, making them easily interchangeable with split
bearings.
The range of units cover shaft dimensions from 35 - 100 mm and
can be used in many industries and applications, such as food &
beverage processing equipment; pulp and paper production; mining
and other heavy industry; agriculture and forestry machinery; fans
and blowers; mixers, crushers, screens; and handling equipment.
