Single-edged lower travel roller for a mini excavator. Internal width between roller flanges 90 mm internal guiding edges to the mini excavator.
Travel 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 the highest 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 product performance and reliability. The range of ITR travel and supporting rollers includes everything from mini excavators to mining machines.
Tension 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 durability of the roller shell is equal to the durability of the track chain links. No maintenance required throughout the roller's lifetime.
Roller shell made from deep-hardened steel and designed to be vibration-resistant. Hardness 50 – 58 HRC.
Shafts and bearings are designed to reduce friction and wear and provide maximum strength. Lubricated for life for minimal maintenance.
Bronzed sliding bearing, ideal for supporting the tension roller. Provides stability and durability, translating to efficient operation of the tensioning system.
The sleeve construction provides a large surface area for better load distribution. A soft bronze coating in the bearing protects against any small 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 ones.
The rubber rings provide the 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 several tread lifetimes, depending on individual conditions.
Oil. Oil-lubricated track rollers use oil, which cools and lubricates better than grease.
