Idler rollers for ITR mini excavators and compact loaders, specially designed for the most demanding applications and environments. The internal width between the roller flanges is 52 mm, and the internal guiding edges for the mini excavator ensure stability.
Idler rollers for ITR 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 precision machining ensure uniformity and consistency of production. Precise assembly, lifetime lubrication, and quality control during and after production ensure product efficiency and reliability. The range of ITR idler and support rollers covers 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 idler roller shell, ideal for use in excavators.
The durability of the idler roller shell 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 life of the idler roller.
Specially designed idler rollers made from deeply hardened steel, characterized by resistance to vibrations. Their hardening level is 50 – 58 HRC, providing reliability and durability in any conditions.
Idler rollers and bearings are designed to reduce friction and wear and to provide maximum strength. Lubricated for the entire life to minimize maintenance.
Bronze plain bearings, perfectly serving as support for the idler roller. They ensure stability and durability, translating 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 ensure proper 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 multiple tread lifetimes, depending on individual conditions.
Oil. Track idler rollers lubricated with oil use a special oil that provides better cooling and lubrication than traditional grease.
