Laufrolle BOBCAT 442
Single-edge lower travel roller for a mini excavator. The internal width between the flanges of the roller is 47 mm, with internal guiding 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 of production. Precise assembly, lifetime lubrication, and quality control during and after production ensure the product's performance and reliability. The range of ITR travel and support rollers covers everything from mini excavators to mining machinery.
Idler rollers from KOMATSU® PC05 (machine operating weight 1.4 tons) to HITACHI® EX2500 (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 lifespan.
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 plain bearing for use in idler rollers, ensuring smooth and quiet operation. An 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 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 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 last several tread lifespans, depending on individual conditions.
Oil. Oil-lubricated track rollers use oil that cools and lubricates better than grease.
