Product Description

The EX100 Top Roller is a precision-engineered component designed for excavators in demanding projects. This key wear part in the undercarriage of EX100-series excavators supports the machine's weight, guides the track chain, and absorbs shocks from uneven terrain.

Working in conjunction with rollers, idlers, and sprockets, it reduces friction, prevents track misalignment, and enhances excavator stability during operations like digging, lifting, and traversing rough ground. Proper maintenance extends undercarriage lifespan and minimizes downtime.

Manufacturing Process & Materials

High-grade Material Selection: Components crafted from premium materials for maximum durability

Inner Roller/Spindle: Alloy steel (SCM440) engineered to withstand significant radial and axial loads
Seals & Lubrication: Nitrile rubber (NBR) seals with lithium-based grease for long-term lubrication
Quality Assurance: Thorough inspection of chemical composition and mechanical properties using spectrometers and hardness testers
