Tension rollers for mini excavators and compact loaders ITR, specially designed for the toughest applications and environments. The internal width between the flanges of the roller is 54 mm, and the internal guide edges to the mini excavator ensure stability.
Tension rollers for mini excavators and compact loaders ITR 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 efficiency and reliability. The range of ITR tension and support rollers includes from mini excavators to mining machines.
Tension rollers for machines from KOMATSU® PC05 (operating weight 1.4 tons) to HITACHI® EX2500 (operating weight 248 tons)
Specialized casing with tension rollers, ideal for use in excavators.
The tread durability of the tension roller casing is equal to the durability of the track chain links. This means that the user does not have to worry about maintenance throughout the entire service life of the tension roller.
Specially designed tension rollers made from deeply hardened steel, characterized by vibration resistance. Their hardening ranges from 50 – 58 HRC, ensuring reliability and durability in all conditions.
Tension rollers and bearings are designed to reduce friction and wear and ensure maximum strength. Lubricated for life to minimize maintenance.
Bronze plain bearing, excellently serving as support for the tension roller. It provides stability and durability, which translates to efficient operation of the tensioning system.
Tension rollers with a sleeve construction provide 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.
Duo-Cone tension rollers. Seals the oil inlet. Duo-Cone tension rollers consist of two metal sealing rings and two rubber ones.
Tension rollers with rubber rings provide proper 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 life cycles, depending on individual conditions.
Oil. Oil-lubricated track tension rollers use special oil, which provides better cooling and lubrication than traditional grease.
