Single-edge lower track roller for a mini excavator. The inner width between the flanges of the roller is 79 mm, with inner guiding 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 of production. Accurate assembly, lifetime lubrication, and quality control during and after production ensure product performance and reliability. The range of ITR track and support rollers covers everything from mini excavators to mining machines.
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 durability of the roller shell tread is equal to the durability of the track chain links. No maintenance required throughout the roller's life.
The roller shell is made from deep-hardened steel and designed to be vibration resistant. Hardening 50 – 58 HRC.
Shafts and bearings are designed to reduce friction and wear and provide maximum strength. Lubricated for life to minimize maintenance.
Bronzed slide bearing for use in tension rollers, ensuring smooth and quiet operation. Ideal solution for precise tensioning.
The bushing 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 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 withstand several tread lifespans, depending on individual conditions.
Oil. Oil-lubricated track rollers use oil, which cools and lubricates better than grease.
