Track roller single-flanged lower for mini excavators. Internal width between the roller flanges 32 mm internal guiding edges for mini excavators
Track rollers for mini excavators and compact loaders ITR 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 precision machining ensure uniformity and consistency in production. Accurate assembly, lubrication for the entire service life, and quality control during and after production ensure the efficiency and reliability of the product. The range of ITR track and carrier rollers includes everything from mini excavators to mining machines.
Track adjusters from KOMATSU® PC05 (operating weight of the machine 1.4 tons) to HITACHI® EX2500 (operating weight of the machine 248 tons)
The roller shell with a single flange is 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 service life of the roller.
The roller shell is made of deep-hardened steel and designed to be resistant to vibrations. Hardness 50 – 58 HRC.
Shafts and bearings are designed to reduce friction and wear while providing maximum strength. Lubricated for the entire service life for minimal maintenance.
Bronze sliding bearing for use in track adjusters, ensuring smooth and quiet operation. An ideal solution for precise tensioning.
The design of the bushing provides a large surface area for better load distribution. The soft bronze coating in the bearing protects against any fine contaminants that may 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 lifetimes of the tread, depending on individual conditions.
Oil. Oil-lubricated track rollers use oil that cools and lubricates better than grease.
