Premium - Grade Material Construction
Crafted from high - strength, wear - resistant alloy material, the 3940059 bushing offers exceptional durability in the demanding environment of diesel engines. The material features a high hardness rating of HRC 35 - 40, providing superior resistance to abrasion and deformation. It also has excellent heat - resistance properties, capable of withstanding continuous operating temperatures of up to 200°C without compromising its structural integrity. Additionally, the bushing is treated with a specialized anti - corrosion coating, enabling it to perform reliably even in harsh conditions with high humidity or exposure to corrosive substances. This premium - grade construction ensures that the bushing can endure the heavy loads and vibrations typical of Cummins engines, maintaining optimal performance over an extended service life.
Wide - Range Compatibility
