| High Light | m22×70 track fasteners ，m22×70 track link assy ，wear resistant track fasteners | ||
The M22×70 Track Fasteners are engineered to provide dependable fastening performance for excavator and bulldozer track link assemblies. Designed to withstand continuous impact, vibration, and high clamping loads, these fasteners securely connect track shoes to track links while maintaining the structural integrity of the complete undercarriage system. Track link assemblies operate under constant stress caused by heavy loads, rough terrain, and continuous crawler movement. High-quality track fasteners play a vital role in preventing loosening, maintaining proper track alignment, and ensuring stable equipment operation.
Our M22×70 track fasteners are designed to maintain stable clamping force throughout long operating cycles, helping operators improve equipment reliability while minimizing unexpected maintenance. Manufactured from premium alloy steel through precision hot forging, CNC machining, and advanced heat treatment, our M22×70 track fasteners combine high wear resistance, superior tensile strength, and excellent fatigue performance. They are widely used for OEM production, aftermarket replacement, equipment overhaul, and preventive maintenance in construction, mining, quarrying, and earthmoving industries.
Developed for equipment working under constant vibration, high impact, and demanding operating environments.
The forging process improves internal material density, increasing structural integrity and mechanical strength.
Machined threads provide accurate engagement, smooth installation, and consistent tightening performance.
Heat treatment enhances surface hardness while maintaining a tough core to resist cracking under heavy loads.
Stable preload helps reduce bolt movement caused by repeated vibration and cyclic loading.
Protective surface treatment improves durability when operating in wet, muddy, sandy, rocky, or dusty conditions.
Our M22×70 track fasteners help customers achieve:
Suitable for numerous types of crawler machinery, including:
Typical installation areas:
Our manufacturing process combines advanced equipment with rigorous quality control to ensure dependable product performance.
High-quality alloy steel is chosen for excellent tensile strength and impact resistance.
Hot forging improves grain flow and enhances the fastener's resistance to deformation and fatigue.
Precision machining guarantees accurate dimensions and thread consistency across every production batch.
Carefully managed quenching and tempering processes optimize hardness, toughness, and wear resistance.
Surface treatment helps prevent corrosion while maintaining a clean and durable finish.
Each batch undergoes multiple inspections before shipment, including:
These procedures ensure consistent quality and dependable field performance.
Our M22×70 track fasteners are widely supplied to:
