Single-edge lower travel roller for a mini excavator. Internal width between the roller flanges 44 mm internal guide edges for 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 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 components of the highest quality. Deep heat treatment and precise machining ensure uniformity and consistency of production. Precise assembly, lifetime lubrication, and quality control during and after production ensure the product's performance and reliability. The range of ITR travel and support rollers covers everything from mini excavators to mining machinery.
Tension rollers from KOMATSU® PC05 (machine operating weight 1.4 tons) to HITACHI® EX25OO (machine operating weight 248 tons)
The roller shell with a single flange used in excavators.
The tread durability of the roller shell is equal to the durability of the track chain links. No maintenance is required throughout the roller's lifespan.
The roller shell is made from deep-hardened steel and designed to resist vibrations. Hardening 50 – 58 HRC.
Shafts and bearings are designed to reduce friction and wear and provide maximum strength. Lubricated for life to minimize maintenance.
The bronze bearing performs excellently as support for the tension roller. It ensures stability and durability, translating into efficient operation of the tensioning system.
The bushing design provides 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 seal. Seals the oil inlet. The Duo-Cone seal consists of two metal sealing rings and two rubber ones.
The 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 several tread lifetimes, depending on individual conditions.
Oil. Oil-lubricated track rollers use oil, which cools and lubricates better than grease.
