Single-edge lower travel roller for a mini excavator. Internal width between the roller flanges 73 mm internal guiding edges for the mini excavator.
Travel rollers for mini excavators and ITR compact loaders are specially designed for the most demanding 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. Precise 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® EX2500 (machine operating weight 248 tons)
Single-flange roller shell used in excavators.
The durability of the roller shell tread is equal to the durability of the track chain links. No maintenance is required throughout the roller's lifetime.
The roller shell is made from deep-hardened steel and designed to withstand vibrations. Hardening 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 for use in idler rollers, ensuring smooth and quiet operation. An 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 ones.
Rubber rings provide adequate 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. Oil-lubricated track rollers use oil, which cools and lubricates better than grease.
