Common CNC Machined Shaft Types
Stepped Shafts for Precision Assemblies
Shafts are critical components in sStepped shafts are widely used in assemblies requiring multiple bearing positions or component interfaces.
Typical features:
- Multiple diameters with tight tolerance control
- Precision fits for bearings and gears
- Smooth transitions to reduce stress concentration
👉 Ideal for mechanical assemblies and automation systems.
Motor & Drive Shafts
In Motor shafts require high concentricity and surface finish to ensure smooth rotation.
Key focus:
- Low runout for vibration control
- Surface finish for bearing compatibility
- Tight tolerances for coupling interfaces
Ensuring efficient power transmission.
Threaded & Custom Feature Shafts
Automotive shafts must withstand dynamic loads and continuous operation.
Key requirements:
- High strength and fatigue resistance
- Accurate fit for gears and couplings
- Surface treatment for durability and wear resistance
Ensuring long-term performance in demanding environments.
