Teflon fibre is a work of friction

FROM the humble frying pan, to bearings – Teflon fibres are working their way through industry.

Such low friction fibres can now be found in bearings as a dry lubricant to prolong service life and reduce operating costs, claims its maker DuPont.

Useful where lubricants are not desired or installation space is at a premium, the lubricating effect is achieved using tiny particles of polytetrafluorethylene (PTFE) deposited on the hardened steel journal or mating part of the bearing during the run-in period.

DuPont expects Teflon-coated bearings to cost more than the equivalent bearings requiring regular lubrication. (01524-782832).
