Heavy-Duty Vertical Stability: DXCG JQ-Type Clamping Rigid Shell Coupling

The DXCG JQ Series Clamping Rigid Shell Coupling  provides a highly stable, completely rigid shaft-to-shaft connection designed specifically for vertical transmission systems, industrial mixers, and deep-tank chemical reactors. When exceptionally long reactor agitator shafts must be manufactured in split sections, or when a vertical gear reducer output shaft needs to link directly with a mixing blade shaft, standard flexible or sleeve couplings cannot provide the necessary axial support. The JQ series features a multi-bolt split clamping sleeve with a built-in internal suspension ring slot, which securely clamps and supports the ends of both vertical shafts without allowing axial slippage.

Precision manufactured from premium 45# medium-carbon structural steel, this classic rigid clamp shell coupling features a straight-through bore layout and offers full structural customization. It provides a rugged, dependable, and highly economical solution for heavy industrial mixing and fluid agitation loops under steady load parameters.

Core Product Advantages

• Premium 45# Grade Structural Steel: Machine-forged from solid 45# carbon steel to ensure high tensile stiffness, superior yield strength, and long-term resistance to structural fatigue under continuous loading.

• Specialized Vertical Suspension Architecture: Features a dedicated internal slot engineered to house an integrated split hanging ring. This ring securely locks the shaft shoulders in place, providing necessary axial support during heavy vertical mixing operations.

• Straight-Through Precision Clamping Bore: Built with a uniform straight-through internal diameter configuration, optimizing surface area contact around the shafts to deliver maximum frictional torque capacity.

• Two-Piece Split Clamp Geometry: The split outer shell design installs or removes quickly from the side without requiring you to disassemble the entire motor array or move heavy agitator blades.

• Engineered for Long Reacting Shaft Joints: An excellent choice for joining multi-section mixer shafts inside deep vessels, or for bridging vertical gearboxes with industrial blending paddles.

• Complete Factory Customization Program: Supported by Apexcoupling’s advanced production plant, we offer extensive custom parameters—including non-standard bore sizes, tailored lengths, specialized split ring dimensions, and anti-corrosive industrial coatings to match your project blueprints.

Operational Engineering Notice: Because JQ-type rigid shell couplings do not provide axial, radial, or angular misalignment compensation, connecting shafts must be accurately leveled and centered during installation. To maximize operational balance at higher speeds, clamping fasteners should be installed in alternating opposite directions.
