Single-edge lower traveling roller for a mini-excavator. The internal width between the roller flanges is 89 mm, with 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 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. Accurate 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 machines.
Tension rollers from KOMATSU® PC05 (machine operating weight 1.4 tons) to HITACHI® EX25OO (machine operating weight 248 tons)
Single-flange roller shell used in excavators.
The durability of the roller shell tread equals the durability of the track chain links. No maintenance is required throughout the life of the roller.
The roller shell is made of deep-hardened steel and designed to resist vibrations. Hardening is 50 – 58 HRC.
Shafts and bearings are designed to reduce friction and wear and provide maximum strength. Lubricated for the lifetime to minimize maintenance.
Bronzed sliding bearing for use in tension 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 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.
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 lifespans, depending on individual conditions.
Oil. Oil-lubricated track rollers use oil that cools and lubricates better than grease.
