🔍 About This Flange Rigid Shaft Coupling Clamp Bracket
This flange coupling is a professional shaft fixing component with a flange base design, specially engineered to secure shafts onto flat surfaces and simplify the installation of other mechanical accessories mounted on shafts. Directly supplied from factory, this coupling is manufactured from high-strength 45 steel. After integrated heat treatment hardening and electroplated surface finishing, it achieves far higher overall hardness than brass and aluminum alloy couplings. It delivers superior wear resistance, excellent anti-deformation performance and extended service life. A comprehensive range of bore sizes from 3mm to 12mm is available to satisfy diverse assembly requirements. Custom machining service is also offered for special non-standard dimension demands.
⭐ Key Features of Our Flange Rigid Shaft Coupling Clamp Bracket
- ✅ Ultra-High Hardness Construction: Heat-treated hardened 45 steel material, harder than aluminum alloy and brass couplings, resistant to cracking and deformation under high torque loads.
- ✅ Rust-Resistant Electroplated Surface: Smooth electroplated finish enhances oxidation and corrosion resistance, suitable for long-term continuous mechanical operation.
- ✅ Reliable Flange Mount Structure: Flange base creates a larger contact area, firmly fixing the shaft onto flat panels for stable vibration-free operation.
- ✅ Precision Matched Thread Specification: Separately equipped with M3 / M4 set screws corresponding to different bore sizes, tight locking and anti-slip during high-speed rotation.
- ✅ Complete Size Selection & Custom Support: Full bore options covering 3mm to 12mm; custom machining available for special equipment application scenarios.
- ✅ Supplied with Complete Fittings: Each unit comes with 2 fixing set screws and one matching hex wrench, ready for direct installation.
- ✅ Wide Versatile Compatibility: Ideal for automation equipment, robot models, DIY mechanical builds, fixture assembly and vertical shaft mounting projects.
- ✅ Round-The-Clock Professional Customer Support: Online service team provides timely guidance on size selection, installation skills and custom processing consultation.

❓ Frequently Asked Questions | Flange Rigid Shaft Coupling Clamp Bracket FAQ
What applications are suitable for this flange rigid shaft coupling bracket?
This flange base rigid shaft fixing collar is widely used for multiple mechanical assembly scenarios: 1. Industrial Machinery: Shaft positioning and fixing for various mechanical equipment; 2. Model & Robot Projects: Robot models, mechanical arms and DIY mechanical modification accessories; 3. Flat Panel Assembly: Vertical installation and fixation of shafts on flat plates; 4. Automation Equipment: Assembly of transmission fixtures and automated machinery components.
What bore sizes and dimensions are available?
Two size series are provided. Series 1: 3mm /4mm /5mm /6mm bore with M3 set screw; Series 2:7mm /8mm /10mm /11mm /12mm bore with M4 set screw. Besides standard sizes, we accept custom machining for non-standard specifications to meet special equipment demands.
What makes 45 steel flange coupling better than aluminum or brass versions?
The 45 steel material undergoes heat treatment hardening, delivering higher hardness and torsion resistance. It is not easy to deform or crack under high torque. The electroplated surface improves anti-corrosion and anti-oxidation properties, achieving longer service life compared with aluminum alloy and copper shaft collars.
Installation recommendations for this flange shaft clamp bracket?
Please confirm the required inner bore size before ordering. When installing, tighten the set screws evenly to prevent shaft deflection. Ensure the shaft and coupling fit closely to maintain stable operation. If you need custom dimensions, contact our customer service in advance.
Are installation accessories included in the package?
Yes. Every flange shaft coupling is supplied with 2 fixing set screws and a matching hex wrench. No extra tools are required for regular assembly.
🏆 Why Choose Our Flange Rigid Shaft Coupling Clamp Brackets?
Our flange rigid shaft coupling collars are constructed from high-strength heat-hardened 45 steel with electroplated anti-rust surface. Compared with aluminum and brass shaft holders, they offer superior hardness, wear resistance and anti-deformation performance. The flange base design provides larger contact surface for stable mounting on flat panels. Matched M3/M4 set screws ensure firm anti-slip locking during high-speed rotation.
