Characteristics of Track Roller
Terris uses a wheel body that has undergone overall quenching treatment, combined with certified floating sealing technology. Ensure the reliability of the product under harsh working conditions of extreme cold or heat through extreme mining overload testing. Effectively improve durability and stability.

Terris Track Roller Craftsmanship
Track roller body: made of high hardenability alloy steel, forged and quenched as a whole to improve the strength and surface wear resistance of the wheel body;
Shaft: Made of high-quality alloy steel, surface quenched and tempered, and polished after grinding the sliding working surface to achieve effective surface roughness and control temperature rise during operation;
Shaft bushing: The wheel system product of large tonnage excavators uses high-strength brass shaft sleeves to enhance the load-bearing capacity of the wheels;
Shaft seat: made of high-strength ductile iron or cast steel material, formed by precision casting, and ground after precision machining of the thrust surface to obtain good surface roughness, reduce working temperature and wear;
Floating oil seal: Designed with high wear resistant floating seal ring material, the grinding working surface is finely ground and polished. After hardness and strength testing, the floating seal rubber ring is subjected to high-temperature aging and compression deformation tests to ensure that all technical indicators of the rubber ring meet the adaptability requirements of working conditions;
Oil product: Select oil products according to the actual working conditions of the host to meet various complex working conditions such as extreme cold and high temperature.
Supply Range
Undercarriage parts for excavators with a pitch ranging from 90mm to 317mm and bulldozers with a pitch ranging from 135mm to 317mm
