ITR tension rollers for mini excavators and compact loaders, specially designed for the toughest applications and environments. The internal width between the roller flanges is 79 mm, and the internal guide edges provide stability for the mini excavator.
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 of production. Accurate assembly, lifetime lubrication, and quality control during and after production ensure the product's performance and reliability. The range of ITR 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 sheath with tension rollers, ideal for use in excavators.
The durability of the tension roller sheath 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 resistance to vibrations. 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 durability. Lubricated for life to ensure minimal maintenance.
Bronze sliding bearing, perfectly suited as support for the tension roller. It provides stability and durability, resulting in 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 deformations and temperature changes from -40°C to 110°C. Duo-Cone seals are designed to withstand several tread lifetimes, depending on individual conditions.
Oil. Track tension rollers lubricated with oil use special oil that provides better cooling and lubrication than traditional grease.
