PC200-8Mo Idler Wheel 20Y-30-00322, Track Idler Made Of 35MnB Alloy Steel For Chassis Component Replacement

This 20Y-30-00322 PC200-8Mo track idler is a professional chassis guide wheel developed specifically for PC200-8Mo series excavator undercarriage replacement and routine equipment maintenance. Different from ordinary low-carbon steel idlers on the market, this model adopts authentic 35MnB alloy steel raw material as the core configuration, featuring better wear resistance, impact toughness and structural stability. Optimized for frequent earthmoving, gravel road and complex construction site conditions, this chassis component delivers longer service life and more stable track guiding performance. As a direct manufacturing factory, we implement full-process material inspection and finished product testing to ensure reliable and consistent aftermarket replacement performance.

Most universal replacement idlers adopt ordinary carbon steel with unstable material composition, which is prone to rapid wear, surface peeling and brittle cracking under long-term complex working conditions. Our 20Y-30-00322 track idler strictly uses standard 35MnB alloy steel, with fixed chemical element ratio and stable mechanical properties. Each batch of raw materials is inspected for composition before production, and finished products undergo hardness testing, dimensional calibration and surface flaw detection. Strict material screening and process control effectively solve the durability points of ordinary chassis parts, achieving more reliable field performance.

• Upgraded 35MnB Alloy Material: Higher hardness and toughness than ordinary steel materials, greatly improving wear resistance and impact resistance for long-term complex site operation.
• Stable Heat Treatment Performance: Uniform overall hardness after professional heat treatment, avoiding local soft spots and premature partial wear.
• High-precision Size Matching: Produced in strict accordance with 20Y-30-00322 standard dimensions, realizing plug-and-play replacement without on-site modification.
• Professional Chassis Adaptation: Optimized for PC200-8Mo chassis load characteristics, keeping track straight and stable, reducing undercarriage auxiliary wear.

This 20Y-30-00322 35MnB alloy steel idler is specially used for PC200-8Mo excavator chassis maintenance and undercarriage part replacement, suitable for earthwork, road renovation and general construction scenarios. All products are treated with anti-rust oil, waterproof and dust-proof wrapping, and packed with thickened wooden boxes for long-distance sea transportation. We support sample verification, small-batch trial orders and large-scale customized wholesale, providing high-cost performance and durable chassis replacement parts for global engineering equipment users.
