ITR tensioning rollers for mini excavators and compact loaders, specially designed for the toughest applications and environments. The internal width between the flanges of the roller is 30 mm, and the internal guiding edges for the mini excavator ensure stability.
ITR tensioning rollers for mini excavators and compact loaders are manufactured from selected materials such as boron steel, high-strength castings, and top-quality components. A full range of sizes and types is available for all popular brands and models. Deep heat treatment and precise machining guarantee 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 tensioning and support rollers covers from mini excavators to mining machines.
Tensioning rollers for machines from KOMATSU® PC05 (operating weight 1.4 tons) to HITACHI® EX2500 (operating weight 248 tons)
Specialist casing with tensioning rollers, ideal for use in excavators.
The durability of the tread of the tensioning roller casing is equal to the durability of the track chain links. This means the user does not need to worry about maintenance throughout the life of the tensioning roller.
Specially designed tensioning rollers made from deeply hardened steel, characterized by resistance to vibrations. Their hardening ranges from 50 to 58 HRC, ensuring reliability and durability in any conditions.
Tensioning rollers and bearings are designed to reduce friction and wear and provide maximum strength. Lubricated for life for minimal maintenance.
Bronze plain bearing for use in tensioning rollers, ensuring smooth and quiet operation. An ideal solution for precise tensioning.
Tensioning rollers with sleeve construction provide 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.
Duo-Cone tensioning rollers. Seals the oil inlet. Duo-Cone tensioning rollers consist of two metal sealing rings and two rubber ones.
Tensioning rollers with 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 lifetimes of the tread, depending on individual conditions.
Oil. Track tensioning rollers lubricated with oil use special oil that provides better cooling and lubrication than traditional grease.
