Design for Stability and Flexibility
We can design integrated bearings that not only create whole system cost savings but improve product performance. The bearings we design for paper path and business machines, such as photo copiers, printers and scanners, have exacting tolerances, as stability for print and image reproduction is essential. Our tooling and moulding teams were able to achieve very accurate bearing manufacture to within 0.05 of a mm across an 8-cavity tool and we developed speciﬁc design and build methods, including precision machining processes, to perfect the pulley form and supply stability in operation.
Compared to an equivalent bush solution, BNL’s plastic bearing design ran faster without compromising stability, providing a marketing beneﬁt for the customer in increased copies per minute. Our double row version of the pulley, can take a higher load, and be used with a metal bracket, allowing ﬂexibility to use the part across other platforms.
Low Torque Without Expensive Lubricants
Our lightweight bearings do not need grease, making the torque very low in comparison to a steel bearing. This is ideal for paper path and business machine applications where there is a risk of lubricant leeching out and marking or damaging the paper being processed. It also saves the cost of expensive lubricants and greases.
