Cutting through grease

High performance oil-free and grease-free vertical pump bearings from Cut To Size Plastics are engineered for long wear life and high abrasion resistance, along with dry start-up capability, eliminating the need for pre-lubrication systems.

The low-friction elastomeric and thermoplastic range of Thordon bearings absorb impact or shock loads with a dampening capacity nearly 500 per cent greater than rubber and with abrasive wear rates far superior to brass and other traditional alternatives. 

Cut To Size Plastics managing director Laurie Green says the self-lubricating bearings reduce abrasion and prevent wear. 

“They also have a lower dry coefficient of friction, which improves efficiency in frequent stop-starts. Low friction bearings also operate longer, wear less and have reduced start-up torque and ‘stick-slip’, high temperature capabilities and improved chemical resistance,” Green said.

ThorPlas-Blue bearings can be used in water andchemicals up to 80°C while polymer grades operate up to 60°C. 

ThorPlas-White is listed by the NSF International Certification and WRAS for NSF/ANSI/CAN 61 Drinking Water System Components, as well as is classified as an accepted material by CFIA.
