Caterpillar Bulldozer Carrier Roller D6H D6R 235-5974
Description
Top rollers carry the chain and the track shoes, often have different wear patterns than bottom rollers. Common wear patterns of top rollers are on the running surface, flange and roller leakage. You can recognize wear by a broken or bent support, a sagged top roller axle, an improperly aligned roller or a stuck roller. If a top roller has a flat side, this means that the top roller is stuck. This is usually caused by sand and/or mud between the top roller and the undercarriage. Regular cleaning of the undercarriage is part of the daily maintenance and helps to prevent this.
TACK offers a complete range with top rollers for both excavators and bulldozers from 0.8 to 100 tons. We produce all 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. 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.
