Product Description
The JQ/JQW Split Clamp Rigid Coupling is a heavy-duty rigid coupling designed for vertical shaft connections, particularly in mixer and agitator applications. Made from high-strength 45# steel with a black oxide finish, this coupling provides reliable torque transmission without flexible elements. Its unique split clamp design with a lifting ring allows for easy installation and secure shaft connection in vertical orientations.
Split Clamp Design – Allows installation without moving connected equipment
Lifting Ring Feature – Integrated suspension ring secures shaft ends in vertical applications
45# High-Strength Steel – Forged and heat-treated for durability
Black Oxide Finish – Corrosion resistance and improved surface hardness
Through-Bore Design – Accommodates full shaft penetration
Keyway Standard – Positive torque transmission with keyed shaft connection

Custom sizes available upon request.
The JQ split clamp coupling features:
Two-piece clamp design – Halves are bolted together around the shaft ends
Integrated lifting ring – Located in the center section, allows suspension of vertical shafts
Keyway standard – Ensures positive torque transmission without slippage
Through-bore – Shafts pass completely through the coupling for maximum engagement
This design is specifically suited for vertical applications such as:
Connecting long agitator shafts in reactors
Joining mixer shafts with reducer output shafts
Suspending vertical equipment from overhead drives
Before Installation:
Ensure precise shaft alignment – this coupling does NOT compensate for misalignment
Clean all mating surfaces thoroughly
Verify key and keyway fit
Installation Tips:
Position the coupling halves around both shaft ends
Insert the lifting ring (for vertical applications)
Tighten bolts progressively in a star pattern
For speeds exceeding 5 m/s surface velocity, dynamic balancing is required
To improve balance, install bolts in alternating directions (forward/reverse)
Chemical reactor agitators
Mixing vessels and blenders
Vertical gearbox to mixer shaft connections
Pharmaceutical processing equipment
Food processing mixers
Wastewater treatment agitators
Heavy industrial transmission systems
As a factory-direct manufacturer, we offer:
Custom bore sizes and keyway dimensions
Non-standard lengths for specific shaft spacing
Modified lifting ring configurations
Special surface treatments upon request
For vertical mixer applications, please provide your shaft diameters and torque requirements for proper sizing.
