Idler rollers for mini excavators and compact loaders by ITR, specially designed for the most demanding applications and environments. The internal width between the roller flanges is 106 mm, and the internal guiding edges for the mini excavator ensure stability.
Idler rollers for mini excavators and compact loaders by ITR 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 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 idler and support rollers covers 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 casing with idler rollers, ideal for use in excavators.
The durability of the idler roller tread is equal to the durability of the track chain links. Thus, the user does not need to worry about maintenance throughout the idler roller's service life.
Specially designed idler rollers made of deeply hardened steel, characterized by vibration resistance. Their hardening ranges from 50 to 58 HRC, ensuring reliability and durability under all conditions.
Idler rollers and bearings are designed to reduce friction and wear and provide maximum strength. Lubricated for the entire service life to minimize maintenance.
Bronze sliding bearing, perfectly suited as support for the idler roller. Provides stability and durability, which translates to 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 adequate 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 idler rollers lubricated with oil use a special oil that provides better cooling and lubrication than traditional grease.
