Tension rollers for ITR mini excavators and compact loaders, specially designed for the toughest applications and environments. The internal width between the roller flanges is 63 mm, and the internal guiding edges for the mini excavator ensure stability.
ITR tension rollers for mini excavators and compact loaders are made 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 ensure uniformity and consistency in production. Accurate assembly, lifetime lubrication, and quality control during and after production ensure product performance and reliability. The ITR range of tension and support rollers includes everything 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 shell with tension rollers, ideal for use in excavators.
The durability of the tension roller shell tread matches the durability of the track chain links. This means the user does not have to worry about maintenance throughout the life of the tension roller.
Specially designed tension rollers made from deep-hardened steel, featuring vibration resistance. Their hardening ranges from 50 – 58 HRC, providing reliability and durability in all conditions.
The tension rollers and bearings are designed to reduce friction and wear and ensure maximum strength. Lubricated for the entire service life to minimize maintenance.
Bronzed sliding 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 bushing 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 proper pressure on both sides of the metal sealing rings. Resistant to permanent deformation and temperature changes from -40°C to 110°C. The 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.
