Product Description

42CrMo4 Hollow Chrome Plated Rod H8: Strength Meets Precision in Lightweight Form

42CrMo4 Hollow Chrome Plated Rod H8 is a high-strength, precision-machined tubular steel shaft engineered for dynamic hydraulic and mechanical systems. Made from alloy steel (42CrMo4), this product is quenched and tempered to increase core strength and then chrome plated to improve wear resistance and corrosion protection.

Its hollow design significantly reduces overall weight while maintaining high mechanical performance, making it ideal for applications where space and efficiency matter. The H8 inner diameter tolerance ensures consistent clearance and seamless integration with matching components, such as rods, guide sleeves, or pistons.

This product serves as a durable Hollow Chrome Plated Shaft, a robust Hollow Chrome Cylinder Rod, or a high-precision Hollow Chrome Linear Shaft across various industries.
