· Product Overview
This precision-engineered linear shaft is custom-manufactured from high-grade 304/316 stainless steel via advanced CNC turning and tapping processes, featuring a long cylindrical main body, a stepped mounting tip at one end, and an internal threaded bore with a retaining collar at the other. Designed for linear motion guidance, structural mounting, or component connection in industrial assemblies, it combines exceptional dimensional accuracy, high tensile strength, and corrosion resistance. The precision-ground surface ensures low friction and smooth operation, while the stepped tip and internal thread enable secure mounting and reliable component integration. Ideal for industrial automation, robotics, and precision machinery applications, this shaft delivers consistent performance in high-stress environments.
· Core Specifications
| Specification | Details |
|---|---|
| Base Material | 304/316 Stainless Steel (standard, excellent corrosion resistance & high rigidity); optional carbon steel for cost-effective applications |
| Surface Finish | Precision ground (Ra ≤ 0.8μm, smooth & wear-resistant); optional passivation for enhanced corrosion resistance |
| Machining Process | CNC precision turning, internal tapping, and step machining (conforming to ISO 2768-m / ISO 965 thread standards) |
| Dimensional Tolerance | ±0.01mm for outer diameter (OD) and shaft concentricity; ±0.02mm for thread pitch and step dimensions |
| Key Features | Long cylindrical main body, stepped mounting tip for alignment, internal threaded bore with retaining collar, and corrosion-resistant stainless steel construction |
· Application Scenarios
This linear shaft serves critical roles across high-performance industries:
- Industrial Automation & Robotics: Linear guide shafts for robotic arms, sliding doors, and automated assembly line actuators
- Automotive & EV Systems: Structural mounting shafts for vehicle sensors, control units, and electric vehicle auxiliary components
- Medical Devices: Non-magnetic guide shafts for portable medical instruments and diagnostic equipment (316L variant for biocompatibility)
- Aerospace & UAVs: Lightweight linear shafts for avionics, payload mounts, and drone control systems
- Test & Measurement: Precision guide rods for laboratory analyzers and data acquisition equipment
- Industrial Machinery: Transmission shafts for pumps, gearboxes, and conveyor systems
· Production Process Introduction
- Design & DFM Validation: Our engineering team optimizes shaft length, diameter, and thread size via Design for Manufacturability (DFM) analysis to ensure maximum strength and installation ease.
- Material Preparation: Premium stainless steel bar stock is cut to size and faced to create a clean starting surface for machining.
- Precision CNC Machining:
- Turning: The long cylindrical body and stepped mounting tip are precision-turned to achieve tight concentricity and a smooth finish.
- Tapping: The internal threaded bore is precision-tapped to match standard thread sizes (M6/M8/M10, etc.).
- Step Machining: The retaining collar at the threaded end is machined to provide axial retention.
- Surface Finishing: The shaft undergoes brushing and passivation to enhance corrosion resistance and surface smoothness.
- Quality Inspection: 100% dimensional inspection via CMM verifies OD, concentricity, and thread accuracy; a functional test ensures smooth linear movement.
- Final Packaging: The shaft is wrapped in anti-scratch film and secured in a custom foam tray to prevent bending or scratching during transit.
· Packaging and Shipping Methods
- Standard Packaging: Each shaft is wrapped in anti-scratch PE film, placed in a custom-cut EPE foam insert inside a reinforced corrugated box, with additional bracing to prevent bending. Bulk orders are secured on wooden pallets with plastic wrapping.
- Shipping Options:
- Express Delivery (3–7 Business Days): DHL/FedEx/UPS for prototype and small-batch orders (full tracking provided).
- Standard Sea Freight (25–40 Business Days): Cost-effective FCL/LCL options for large-volume production orders, with full customs documentation support.
- Custom Packaging: Branded labeling, barcoding, and custom tray inserts are available to align with your independent store’s brand guidelines and inventory management needs.

· Frequently Asked Questions (FAQ)
What is your Minimum Order Quantity (MOQ)?
Our MOQ is flexible to suit your independent store’s e-commerce needs:
- Prototypes/Samples:1 piece available for custom design validation.
- Production Runs: Starting at 50+ pieces for standard configurations. We specialize in low-volume, high-precision custom fabrication to match your online store’s demand.
What are your typical lead times?
- Prototype/Sample Orders: 7–10 business days from final CAD design approval (includes machining and finishing).
- Mass Production: 15–25 business days, depending on order volume, shaft length, and custom thread requirements.
- Rush Service: Expedited production (4–6 days for samples) is available upon request for urgent restocks.
Can you accommodate full custom modifications?
Absolutely. We offer end-to-end customization to align with your independent store’s product offerings:
- Size & Shape Customization: Custom overall length, outer diameter (OD), and step dimensions to match your specific mechanical requirements.
- Thread Customization: Custom thread types (metric/imperial), pitch, and depth to meet your fastening needs.
- Feature Modifications: Custom stepped tip profiles, external threads, or additional mounting holes for specialized integration.
- Material Upgrades: Switch between 304 stainless steel (corrosion resistance) or 316L stainless steel (medical/high corrosion) based on your application.
- Surface Finish Options: Custom plating (zinc/nickel), anodizing, or black oxide for enhanced corrosion resistance or aesthetic appeal.
- Branding & Traceability: Laser engraving of logos, part numbers, or batch codes for full product traceability and inventory management.
