Obere Rolle MOROOKA MST800
Upper support roller with mounting brackets (caps), without guiding edges. External width between the internal flanges or the internal flange width of the roller: 393 mm
Support rollers for ITR mini excavators are specially designed for the toughest applications and environments.
A full range of sizes and types is 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 in production. Precise assembly, lifetime lubrication, and quality control during and after production ensure product performance and reliability.
The range of ITR travel and support rollers covers everything from mini excavators to mining machines, from KOMATSU® PC05 (machine operating weight 1.4 tons) to HITACHI® EX25OO (machine operating weight 248 tons)
ITR undercarriage components are developed, designed, and engineered by USCO engineering and R&D departments, using the latest CAD systems and in collaboration with partner universities. The ITR undercarriage product line is entirely managed in-house, from the purchase of raw materials, through the design of components, mechanical processing, heat treatment, through the entire assembly process to final inspection. Numerous quality checks are conducted starting from the purchase of raw materials. The controls are based on knowledge and experience in metallurgical processes and materials engineering.Functions of the upper support rollers: They support the track between the sprocket and the tensioning 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 range from 50 to 58 HRC. Shafts and bearings are designed to reduce friction and wear and to provide maximum strength. Lubricated for life to minimize maintenance.
Bronzed 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 could damage the shaft and seals. The Duo-Cone seal consists of two metal sealing rings and two rubber rings. 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 several tread lifetimes, 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 forestry machines. Production flexibility and design experience also position the ITR undercarriage line well to deliver "custom" products for special applications. Tractors, track bulldozers, mini excavators, compact track loaders, forestry machines, hydraulic excavators, felling machines, cranes, pipe layers, combine harvesters, asphalt pavers, mobile crushers...
