Plastic bearings roll away printer problems
Reliability, easy set-up and modular components were key issues for the Codeology team when designing its P100 printer/applicator.
Mainly steel and aluminium, the machine has to cope with life in demanding factory environments and Codeology wanted to design out some traditional printer/applicator problems, such as roller bearings which need lubricating and are susceptible to dust.
The answer was found in igus low-cost iglidur injection moulded plain bearings, which are self-lubricating, impervious to dirt and fit straight onto a shaft. The main drive roller spindle of the P100 uses an iglidur G polymer plain flanged bearing, while iglidur G sleeve bearings are used for the stand winding handle and rack and pinion spindles.
As the hand wound spindles rotate rarely and at low speeds, bearing clearances become less important than usual. This has allowed Codeology to cut bearing holes into the 3mm stainless steel side plates while they are being laser cut. The bearings can then simply be pushed straight in.
