ZAX240
The ZAX240 Guide Wheel is a precision-engineered excavator undercarriage idler designed to maintain stable track guidance and dependable performance in demanding working environments. Manufactured from premium cast alloy steel using advanced precision casting, CNC machining, induction hardening, and heat treatment processes, this guide wheel delivers exceptional durability, dimensional accuracy, and long-term reliability.
The precision-machined wheel profile maintains consistent engagement with the track chain, reducing lateral movement and promoting smoother crawler travel. Stable engagement also helps reduce uneven wear on track links, rollers, and sprockets.
Constructed from premium alloy steel with optimized rib reinforcement, the guide wheel offers excellent resistance to deformation, cracking, and impact damage during continuous heavy-duty operation.
The running surface is induction hardened to create a durable wear layer that withstands continuous contact with track links while maintaining a tough core for improved shock absorption and fatigue resistance.
The floating Duo Cone seal effectively retains internal lubricant while preventing mud, dust, sand, and water from entering the bearing chamber, helping extend bearing life and reduce maintenance.
Every ZAX240 guide wheel is produced using advanced CNC machining and strict dimensional control to ensure accurate installation, smooth rotation, and dependable OEM compatibility.
