Bulldozer track rollers are key components for stable operation of bulldozers. When your bulldozer chassis encounters abnormal noise, oil leakage, or track deviation, derailment, etc., we should prioritize the use of bulldozer track rollers. While supporting the weight of the fuselage and guiding the track to run smoothly, it also bears the internal and external friction and impact force during high-speed operation. Therefore, the optimal design structure and good material components are indispensable. The unique operation of the bulldozer requires a single-flange and double-flange wheel body for guidance. If only the flange and single flange of the guide wheel are used under heavy loads and complex terrain, it is not enough to protect the track from running correctly.
TERRIS cites the mainstream structural design of bulldozer track rollers, which are wheel body, bearing, sealing assembly, shaft, sleeve and collar, and adopts a detachable structure to facilitate the replacement of shafts or sealing assemblies. The wheel bodies of single and double flanges are made of medium carbon alloy steel, which takes into account both strength and toughness. After high-frequency quenching, tempering and carburizing hardening, the hardness and depth of the surface hardened layer are enhanced to extend the service life; the sealing device adopts floating seal, and multiple metal rings and rubber rings enable the bulldozer rollers to cope with high pressure and high speed operation. The pin shaft and the wheel body are processed by high-precision CNC to ensure that the center of gravity is symmetrical and the concentricity is within the controllable range to avoid abnormal vibration and wear. Ensure durability and reliability in complex heavy-load environments.
When choosing bulldozer rollers and using them, if you want to take into account the working environment and product stability and reliability, to improve your efficiency and cost control, you can choose to use Terris products, and our team will quickly provide you with solutions.
