Crystalline structure absorbs energy in high speed Power-Core roller.

A special design by Intech’s engineering staff, using a composite tire material, a tested method of manufacturing and assembly, all contribute to the exceptionally quiet performance of Intech Power-Core™ rollers.

Intech Power-Core™ rollers


The design marries a precision roller or ball bearing with an Intech Power-Core composite tire. The quiet roller ride can be attributed to the tire material with its tension-free, homogeneously crystalline structure, achieved through a unique casting process. This fine crystalline structure exhibits excellent energy absorbing properties while resisting flat development under load, while the Power-Core tire also protects the metal rail against wear.

Tires are precision-machined, and then heated in an oven to 250° to 300° F before the bearing is pressed in through a specially designed snap-in lip. After cooling, the tire is effectively shrunk onto the bearing. The precision-machined tire, with OD tolerance within 0.0001”, has excellent roundness contributing to the smooth and quiet ride.

The expected life of the roller in number of roll-overs, and flat-free time under load, are determined with a calculation and data developed by a leading university.
