    Description

    TACK offers a complete range with its rollers for both excavators and bulldozers from 0.8 to 100 tons. We produce all bottom rollers and top rollers based on OEM specifications. The production is finished on high-tech CNC machinery with precision tools, high-grade seals and bronze bushings (bimetal).

    We have designed the bottom and top rollers with reinforced flanges and unique  seals. We forge high-quality steel using a special method. Heat treatments make the excavator rollers or dozer rollers extra tough and thus wear-resistant. This guarantees a long service life, even with intensive use.
