Obere Rolle TAKEUCHI TCR50
Upper support roller without mounting brackets (caps), without guide edges External width between internal flanges or internal flange width of the roller: 80mm
Support rollers for ITR mini excavators are specially designed for the toughest applications and environments.
A full range of sizes and types are available for all popular brands and models. ITR rollers are forged products, made from selected materials such as boron steel, high-strength castings, and top-quality components.
Deep heat treatment and precise machining ensure uniformity and consistency of production. Accurate assembly, lifetime lubrication, and quality control during and after production ensure product performance and reliability.
The range of ITR travel and support rollers includes from mini excavators to mining machines, from KOMATSU® PC05 (machine operating weight 1.4 tons) to HITACHI® EX2500 (machine operating weight 248 tons)
ITR undercarriage components are developed, designed, and constructed by USCO's engineering and R&D departments, using the latest CAD systems and in collaboration with partner universities. The ITR undercarriage product line is fully self-managed. From the purchase of raw materials, through the design of elements, mechanical processing of elements, heat treatment, the entire assembly process, up to and including final inspection. Numerous quality controls are carried out starting from the purchase of raw materials. The controls are based on knowledge and experience in the field of metallurgical processes and material engineering.Functions of the upper support rollers: They support the track, between the sprocket and the tension wheel. The durability of the roller tread matches the durability of the track chain links. Support rollers have induction-hardened shells to increase surface hardness, wear resistance, and fatigue strength while maintaining core properties. Values in the range of 50 – 58 HRC. Shafts and bearings are designed to reduce friction and wear and ensure maximum strength. Lubricated for the entire lifespan to minimize maintenance.
Bronze plain bearing. The design provides a large surface area for better load distribution. The soft bronze coating in the bearing protects against any small contaminants that may damage the shaft and seals. The Duo-Cone seal consists of two metal sealing rings and two rubber ones. The rubber rings provide appropriate pressure on both sides of the metal sealing rings. Resistant to permanent deformation and temperature changes from -40°C to 110°C. Duo-Cone seals are designed to withstand multiple tread lifespans, depending on individual conditions.
The ITR undercarriage product line offers the most complete range available on the market, covering standard applications for excavators and bulldozers along with a full range of undercarriage components for asphalt, drilling, and timber harvesting machines. Production flexibility and design experience also position the ITR undercarriage line well to deliver "custom-made" products for special applications. Tractors, crawler bulldozers, mini excavators, compact track loaders, forestry machines, hydraulic excavators, logging machines, cranes, pipe layers, harvesters, asphalt pavers, mobile crushers...
