Bearings for demanding applications - from stock
Manufactured by SNR, the new Topline bearings brand is said by UK supplier Nadella to be the first range of bearings for demanding applications available from stock
The end rings have a slightly larger outer diameter than the nominal diameter of the bushing and this design provides an interference fit with the housing without any reduction in radial clearance.
This eliminates the need for gauging after fitting and enables accurate control of the clearance or preload.
The new design further simplifies mounting as adhesive bonding in the housing is not necessary.
Bushings are available to fit shaft diameters from 12 to 30mm and they have been designed to suit h6 diameter shafts.
Options include one or two integral lip seals and factory-matched shafts for greater control of clearance.
Typical applications will include: automation, converting, machine tools, mechanical handling, packaging, printing and medical equipment.
