Single-edge bottom travel roller for a mini excavator. The internal width between the roller flanges is 86 mm, with internal guiding edges for the mini excavator.
Travel rollers for mini excavators and compact loaders ITR are specially designed for the toughest applications and environments. A full range of sizes and types are 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 of production. Accurate assembly, lifetime lubrication, and quality control during and after production ensure product performance and reliability. The range of ITR travel and support rollers covers everything from mini excavators to mining machinery.
Idler rollers from KOMATSU® PC05 (machine operating weight 1.4 tons) to HITACHI® EX25OO (machine operating weight 248 tons)
The single-flange roller shell used in excavators.
The durability of the roller shell tread equals the durability of the track chain links. No maintenance required throughout the roller's lifespan.
The roller shell is made from deeply hardened steel and designed to be vibration-resistant. Hardening 50 – 58 HRC.
Shafts and bearings are designed to reduce friction and wear while providing maximum strength. Lubricated for the entire lifespan to ensure minimal maintenance.
Bronzed plain bearing, excellently suited as a support for the idler roller. Provides stability and durability, resulting in efficient operation of the tensioning system.
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.
The 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 last several tread lifespans, depending on individual conditions.
Oil. Oil-lubricated track rollers use oil, which cools and lubricates better than grease.
