High Strength CNC Machining Shafts - Durable forged and cast roller shafts for mechanical and automotive systems
Product Overview
Our high-precision CNC machined shafts are engineered for superior performance in demanding mechanical and automotive applications. Manufactured using high-strength forged and cast steel, these roller shafts deliver exceptional durability, fatigue resistance, and smooth power transmission under extreme loads. Ideal for drivetrains, gearboxes, industrial machinery, and heavy equipment.
Key Features & Benefits
✔ Ultra-Precise CNC Machining – Tight tolerances (±0.005mm) ensure perfect fit and alignment in critical systems.
✔ Premium Materials – Made from forged alloy steel (4140, 4340) or high-grade cast steel for maximum strength and wear resistance.
✔ Optimized Durability – Heat-treated and stress-relieved to enhance hardness (HRC 28-55) and prevent deformation under high torque.
✔ Smooth Performance – Precision-ground and polished surfaces reduce friction, vibration, and energy loss.
✔ Customizable Designs – Available in splined, keyed, or threaded configurations for seamless integration.
