Tension rollers for ITR mini excavators and compact loaders, specially designed for the toughest applications and environments. The internal width between the flanges of the roller is 90 mm, and the internal guiding edges for the mini excavator ensure stability.
Tension rollers for ITR 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 in production. Accurate assembly, lifetime lubrication, and quality control during and after production ensure product performance and reliability. The range of ITR tension and support rollers covers from mini excavators to mining machinery.
Tension rollers for machines from KOMATSU® PC05 (operating weight 1.4 tons) to HITACHI® EX2500 (operating weight 248 tons)
Specialized tension roller jacket, ideal for use in excavators.
The durability of the tension roller jacket tread is equal to the durability of the track chain links. This means the user does not have to worry about maintenance throughout the entire service life of the tension roller.
Specially designed tension rollers made from deep-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 provide maximum strength. Lubricated for the entire service life to minimize maintenance.
Bronze-plated slide bearing, perfectly suited as support for the tension roller. It ensures stability and durability, translating into efficient operation of the tensioning system.
Tension 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 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 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 lifespans, depending on individual conditions.
Oil. Track tension rollers lubricated with oil use a special oil that provides better cooling and lubrication than traditional grease.
