Laufrolle LIBRA 116 S
Single-edge lower travel roller for mini excavators. Internal width between the roller flanges is 20 mm, with internal guiding edges for mini excavators.
Travel rollers for ITR mini excavators and 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. Accurate assembly, lifetime lubrication, and quality control during and after production ensure product performance and reliability. The range of ITR travel and support rollers includes 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)
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 be resistant to vibrations. Hardening is between 50 – 58 HRC.
Shafts and bearings are designed to reduce friction and wear and provide maximum strength. Lubricated for life to minimize maintenance.
Bronzed plain bearing used in tension rollers ensures smooth and quiet operation. Ideal 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 can 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 rings.
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.
