ITR idler rollers for mini excavators and compact loaders, specially designed for the toughest applications and environments. The internal width between the roller flanges is 48 mm, and the internal guiding edges for the mini excavator ensure stability.
ITR idler 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 ensure uniformity and production consistency. Accurate assembly, lifetime lubrication, and quality control during and after production ensure product performance and reliability. The range of ITR idler and support rollers includes everything from mini excavators to mining machines.
Idler rollers for machines from KOMATSU® PC05 (operating weight 1.4 tons) to HITACHI® EX2500 (operating weight 248 tons)
Specialist shell with idler rollers, ideal for use in excavators.
The tread durability of the idler roller shell is equal to the durability of the track chain links. This means the user does not need to worry about maintenance throughout the operational life of the idler roller.
Specially designed idler rollers made from deep-hardened steel, characterized by vibration resistance. They are hardened to 50 – 58 HRC, ensuring reliability and durability under any conditions.
Idler rollers and bearings are designed to reduce friction and wear and provide maximum strength. Lubricated for life to ensure minimal maintenance.
Bronze sliding bearing, perfect for supporting the idler roller. It provides stability and durability, resulting in efficient operation of the tensioning system.
Idler 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 idler rollers. Seals the oil inlet. Duo-Cone idler rollers consist of two metal sealing rings and two rubber ones.
Idler rollers with rubber rings provide the correct 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 lifetimes, depending on individual conditions.
Oil. Track idler rollers lubricated with oil use special oil, which provides better cooling and lubrication than traditional grease.
