Beveller Comparison

New Narrow Beveller   Old Beveller

75mm (2.9") upwards

Distance between bevels (roller length)

175mm (6.9") - 240mm (9½")

Longer rollers could be made but special covers would be needed for the extraction ductwork

Low wear due to high dimensional accuracy


Wear results form high cutting forces.  These high forces are in turn due to slight dimensional inaccuracies in the castings and large 'lands' on the cutting components.

Steel construction and a more rigid bearing arrangement means that frame wear is eliminated

Frame wear

Aluminium construction and essential clearance in the needle roller bearings caused high wear rates in the bearings and frame

No greasing required


Regular greasing required

Parts are easy to replace since the moving cutter cartridge is attached to the housing by just one bolt.

Replacement of parts can be done on the shop floor without risk of reduced bearing/seal life through contamination.

Component replacement

Replacing any of the 'Common spare parts' involves dismantling the cutter, shaft, bearings and associated components.  There is a high risk of contaminating the bearings with dust and fluff during this process which would result in bearing damage.
