Sturdy Performance from a Top Excavator Undercarriage Factory
Durability and Stability for Heavy Machinery
Durability, load-bearing capacity, and extended service life are essential for excavator and bulldozer applications. As one of the most important parts of the undercarriage system, the track roller(https://www.rhkmachinery.com/product-category/track-roller/) is used to support the weight of machinery, maintain track tension, and guide the track to prevent wandering.
Yongxing Engineering Machinery Co., Ltd. operates as a professional plant engaged in the development of undercarriage parts for construction machinery. Based on the RHT model, the RHK track roller has become a leading product in the industry, known for its structural strength, wear resistance, and long working life.
Accurate Machining for the Ultimate Stability
RHK track rollers adopt through hardening or surface quenching, achieving a hardness above HRC45 for increased wear resistance. All rollers are perfectly fitted to your undercarriage system for optimal performance. They support the machine’s track and provide excellent rolling intensity.
Whether you work in mining, construction, or forestry, RHK rollers offer outstanding support and cushioning, ensuring smoother movement and reduced vibration.
Built by an Undercarriage Certified Manufacturer
As a certified excavator undercarriage factory(https://www.rhkmachinery.com/), we maintain a high standard of quality. We use special steel, maintain high-volume stock, and ensure product continuity. All track rollers undergo testing across multiple parameters, including stress, abrasion, and hydraulic sealing. Surface hardening levels are strictly measured and controlled.
This unwavering commitment to quality has helped RHK establish lasting partnerships with top equipment brands like Komatsu, Caterpillar, Hyundai, Hitachi, and others.
Compatible with High-Wear Parts Like Bucket Pins
To ensure full machine safety, RHK also manufactures high-strength wear parts, such as the bucket pin, which connects the bucket and boom/arm. Like our rollers, the bucket pins are made with superior construction and wear resistance to maintain durability across your excavator system.
For example, the D5 features a track roller frame with a positive idler yoke design that increases durability. As Horsch notes:
“The heavy-duty roller and good bucket pin give it a strong, longer-lasting undercarriage, which helps to extend maintenance intervals and reduces your downtime.”
