Maximum Zero-Backlash Rigidity: JQ 45# Steel High-Torque Clamping Coupling

The JQ 45# Steel High Rigidity Clamping Coupling is engineered to meet the strict demands of industrial mixing equipment manufacturers, automated material handling systems, and precision fluid-drive applications. When mechanical sub-assemblies require absolute torsional stiffness and zero-backlash torque transmission, flexible couplers can introduce unwanted rotational wind-up or axial lag. The JQ series utilizes an integrated, single-piece rigid sleeve structure that wraps completely around the shaft circumference, creating an incredibly secure friction grip using heavy-duty clamping screws.

Machined from premium high-strength 45# structural steel and finished with a professional black oxide anti-corrosion coating, this coupling delivers superior stability, immense fatigue resistance, and higher allowable torque thresholds than standard aluminum variations. It safely accommodates rated torques from 1 N·m up to 220 N·m, making it an essential component for heavy industrial mixing loops, printing shops, and construction machinery.

Core Product Advantages

• High-Strength 45# Steel Integrated Structure: Precision-machined from solid 45# structural carbon steel into a single, seamless body, providing ultimate torsional rigidity and resistance to high-torque deformation.

• Corrosion-Resistant Black Oxide Surface: Finished with an industrial-grade black oxide treatment to shield the raw steel from moisture, splash oil, and harsh chemical misting common in fluid-mixing plants.

• Secure Fastening via Clamping Screws: Employs a non-marring clamping screw design that applies uniform compression across the shaft surface, maximizing frictional holding power without scarring or dimpling the shaft metal.

• Impressive 1 to 220 N·m Torque Envelope: Engineered to transmit continuous high torque effortlessly, preventing slippage or rotational play under severe start-stop or reversing cycles.

• High-Velocity Rotation Balance: Compact physical design supports safe, high-speed applications running anywhere from 7,500 RPM up to 39,000 RPM.

• Wide Dimensional Selection Matrix: Features an outer diameter array ranging from 16mm to 95mm and total lengths spanning 16mm to 126mm to blend seamlessly into modern machine footprints.

• Tailored OEM/ODM Factory Customization: Backed by Apexcoupling’s advanced manufacturing facility, we offer a flexible customized size program to accommodate non-standard bores, stepped shaft mismatches, or specialized lengths built directly to your blueprints.
