PR722 PR731 TRACK ROLLER (SF/DF)
Description
The materials available for Track roller is 40Mn2、35MnB、50Mn, depending on working conditions.The rollers are normalized with precision forging before overall heat treatment to achieve surface hardness or HRC52-6 and the depth of hardened layer reaches more than 7-10mm(HRC45). This ensures higher durability with high impact resistance and surface wear resistance on the contact surface of the roller. High quality floating seals and lubricating system are used to adapt to different climate and temperature The track and carrier rollers is able to work under severe working conditions or climate ranging from -45℃~120℃, keeping the components free from maintenance.
Our Track Roller is welded before precision machining in vertical CNC turning lathe and hence, there is no concentricity errors.The process gives unparalleled quality quality advantage over that of precision machning before welding. Therefore, the operation of roller is be guaranteed against occurrence of rapid wearing problems, which significantly improves service life of the products.
* Our Track Rollers are manufactured using top-grade materials such as 40Mn2, 35MnB, and 50Mn, ensuring superior strength and resilience.
The rollers undergo a meticulous process of precision forging and overall heat treatment, resulting in a surface hardness of HRC52-56 and a hardened layer depth of 7-10mm (HRC45). This meticulous process guarantees that our Track Rollers offer unparalleled durability, high impact resistance, and exceptional surface wear resistance, making them ideal for demanding applications.
Our Track Rollers are specifically designed for use with PR722 and PR731 models, and are available in both single flange (SF) and double flange (DF) configurations. Whether you are operating in challenging terrains or extreme working conditions, our Track Rollers are engineered to deliver reliable performance and longevity.
With a focus on precision engineering and quality manufacturing, our Track Rollers are built to withstand the rigors of heavy-duty applications, providing smooth and efficient operation while minimizing downtime and maintenance costs.
In conclusion, our Track Rollers are the perfect choice for customers seeking high-performance, durable, and reliable undercarriage components. Backed by our commitment to quality and customer satisfaction, our Track Rollers are the ideal solution for your heavy equipment needs.
