SKF launches latest Concentra roller bearing units

SKF has launched its latest generation of Concentra roller bearing units, which can be mounted 20 minutes faster than conventional split housings, saving costs in mounting and maintenance.

The units enable accurate mounting, resulting in high bearing performance and a longer bearing life, according to the company.

This is intended to contribute to improved performance in manufacturing machinery and ancillary equipment.

The units use SKF's 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 predetermined torque, using the 'smart' Allen key provided.

This method ensures that the bearing is locked 100 per cent concentrically around the shaft, improving bearing and machine performance and facilitating dismounting.

The 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 lubrication free under certain conditions.

The design of the latest units offers a range of additional benefits in industrial applications.

For example, shaft damage is eliminated as 100 per cent 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 interchangeable with split bearings.

The range of units covers shaft dimensions from 35mm to 100mm and can be used in many industries and applications, such as food-and-beverage processing equipment, pulp and paper production, mining and other heavy industries, agriculture and forestry machinery, fans and blowers, mixers, crushers and screens and handling equipment.
