· Product Overview
These precision-engineered split clamping couplings are high-reliability power transmission components crafted from 304 stainless steel—an industrial-grade material valued for exceptional corrosion resistance, high tensile strength, and food-safe compliance. Designed to securely connect two shafts and transmit torque with zero backlash, each coupling features:
- A split (slotted) cylindrical body (for easy installation and shaft clamping)
- Multiple socket head cap screw holes (for uniform clamping force)
- Precision-machined bore (for tight shaft fit)CNC-machined to ultra-tight tolerances and finished with a passivated polished surface, these couplings deliver precise torque transfer and consistent performance, making them ideal for demanding mechanical systems where accuracy and durability are critical.
· Core Specifications
- Material: 304 Stainless Steel
- Tensile Strength: ≥515 MPa (rigid for high-torque power transfer)
- Corrosion Resistance: Passed 72-hour salt spray test (suitable for humid/industrial environments)
- Food-Safe: Compliant with FDA 21 CFR 175.300 (ideal for food-processing equipment)
- Manufacturing Standard: ISO 9001-Certified
- Key Processes: CNC Turning (cylindrical profile) → Precision Drilling (clamping screw holes + alignment ports) → Splitting (slotted body) → Deburring → Surface Passivation → CMM Inspection
- Standard Parameters:
- Bore Diameter: 15–25mm (customizable to shaft sizes)
- Outer Diameter: 40–60mm (matched to bore size for optimal torque capacity)
- Length: 30–50mm (balanced for rigidity and compactness)
- Dimensional Tolerance: ±0.01mm (ensures zero-backlash shaft fit)
- Surface Finish: Passivated polished (scratch-resistant, rust-proof, and smooth for low-wear operation)
· Application Scenarios
These split clamping couplings excel in precision torque transfer and shaft connection systems:
- Industrial Automation: Conveyor system shaft couplings, robotic arm joint drive couplings, and gearbox output shaft connectors.
- CNC Machines: Stepper/servo motor couplings for axis drives, ensuring accurate motion control and zero backlash.
- Packaging Machinery: Material feeding shaft couplings, labeling machine drive connectors, and sealing system actuation components.
- Medical & Laboratory Equipment: Precision instrument shaft couplings (304 SS meets hygiene standards) and diagnostic machine drive components.
- Food & Beverage Processing: Sanitary conveyor shaft couplings and packaging machine component connectors (compliant with food-safety regulations).
· Production Process Introduction
- Raw Material Sourcing: Procure certified 304 stainless steel round bars (traceable to quality standards) and cut to blank length.
- CNC Turning: Use high-precision CNC lathes to machine the cylindrical outer profile and precision bore in a single setup for maximum concentricity.
- Precision Drilling: Drill clamping screw holes and alignment ports to ensure uniform clamping force and installation accuracy.
- Splitting Operation: Create the split (slotted) body to enable shaft clamping and tool-free installation.
- Deburring & Finishing: Remove sharp edges from slots, holes, and bore surfaces to prevent component wear and ensure safe handling.
- Surface Passivation: Apply a chemical passivation treatment to enhance 304 SS’s natural corrosion resistance.
- Quality Inspection: Perform CMM dimensional scanning, bore fit testing, and torque capacity validation to verify compliance with design specifications.
· Packaging and Shipping Methods
- Packaging:
- Individual Pairs: Protected with anti-scratch foam padding, sealed in moisture-proof plastic bags, and packed in labeled cardboard boxes (marked “Paired Split Clamping Couplings”).
- Bulk Orders: Secured in foam-lined wooden crates with additional bracing to prevent deformation during transit.
- Shipping Options:
- Express Delivery (DHL/FedEx): 3–5 business days for prototype or small-quantity orders.
- Air Freight: 7–10 business days for medium-batch production runs.
- Sea Freight: 20–25 business days for large-volume bulk orders.All shipments include full tracking and damage insurance.
