Plastic Shaft Technology

Traditionally, a solid steel shaft reaching the full width of the machine with several polyurethane tyres attached and a bearing at each end to support it would have been used. But through extensive R&D and close collaboration with our customers, BNL has devised many alternative solutions incorporating steel, aluminium, patented plastic and rubber twin-shot and over-moulded combinations to ensure the right shaft for the right job. Our patented nylon shaft with over-moulded elastomer rollers for a computer scanner is a fine example of our expertise in this area.

 

 

Patented twin-shot printer feed shaft with integrated
elastomeric rollers and gear teeth		   Prototype through-moulded shaft
 

Double row idler roller for photocopier   High stiffness twin-shot shaft with integrated roller, gear and snap connection
 

Pinch roller shaft assembly for photocopier, comprising
plastic bearing rollers snap-fitted on to a light weight
metal shaft		   Flexible, low friction shaft with twin-shot soft flipper
fingers

 

Through the integration of additional features such as clip-on rollers and integral ball bearings, our dedicated in-house design team is able to maximise functionality, reduce the number of components, suppliers and assembly time, thereby delivering whole system cost reductions.
