Single-flange lower roller for a mini excavator. The internal width between the roller flanges is 30 mm, with internal guide edges for the mini excavator.
Track rollers for ITR mini excavators and compact loaders are specially designed for the toughest applications and environments. A full range of sizes and types is available for all popular brands and models. ITR rollers are forged products made from selected materials such as boron steel, high-strength castings, and top-quality components. Deep heat treatment and precise machining ensure uniformity and consistency in production. Accurate assembly, lifetime lubrication, and quality control during and after production ensure the product's performance and reliability. The range of ITR track and support rollers covers everything from mini excavators to mining machines.
Idler rollers from KOMATSU® PC05 (machine operating weight 1.4 tons) to HITACHI® EX2500 (machine operating weight 248 tons)
Single-flange roller shell used in excavators.
The tread life of the roller shell is equal to the life of the track chain links. No maintenance is required throughout the roller's lifetime.
The roller shell is made from deeply hardened steel and designed to be vibration-resistant. Hardness 50 – 58 HRC.
Shafts and bearings are designed to reduce friction and wear and ensure maximum durability. Lubricated for the entire lifespan to minimize maintenance.
Bronzed slide bearing used in idler rollers, providing smooth and quiet operation. Ideal solution for precise tensioning.
The sleeve design provides a large surface area for better load distribution. The soft bronze coating in the bearing protects against any minor contaminants that could damage the shaft and seals.
Duo-Cone seal. Seals the oil inlet. The Duo-Cone seal consists of two metal sealing rings and two rubber rings.
Rubber rings provide appropriate 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 lifespans, depending on individual conditions.
Oil. Oil-lubricated track rollers use oil, which cools and lubricates better than grease.
