Laufrolle MOROOKA MST800
Single-flange lower track roller for mini excavator. Internal width between the roller flanges is 120 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 in production. Accurate assembly, lifetime lubrication, and quality control during and after production ensure the product's efficiency and reliability. The range of ITR track and carrier 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's tread is equal to the durability of the track chain links. No maintenance is required throughout the roller's lifetime.
The roller shell made of deeply hardened steel and designed to be vibration-resistant. Hardness 50 – 58 HRC.
Shafts and bearings are designed to reduce friction and wear and provide maximum strength. Lubricated for the entire lifespan to minimize maintenance.
Bronze slide bearing, perfect for supporting the tension roller. It provides stability and durability, resulting in efficient operation of the tensioning system.
The bushing construction provides a large surface area for better load distribution. The soft bronze coating in the bearing protects against any minor contamination 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, which cools and lubricates better than grease.
