Hebei Speed Torque Transmission Technology Co., Ltd., established in 2017 with a factory spanning 3,000–5,000 square meters and a dedicated team of 101–200 professionals, presents the Adjustable Range Universal Flexible Coupling – a multi-purpose connector engineered for precision shaft joint applications. This coupling is designed to accommodate misalignment, reduce vibration, and transmit torque smoothly across various industrial systems. With our ISO9001 certified manufacturing processes, we ensure consistent quality and reliability, making this coupling an ideal choice for engineers seeking a versatile, durable, and cost-effective solution for connecting shafts in motors, pumps, gearboxes, and automation equipment.
The universal flexible coupling stands out with its adjustable bore range, allowing quick adaptation to different shaft sizes without requiring multiple inventory parts. Its flexible element effectively absorbs angular, parallel, and axial misalignments, protecting connected components from premature wear. Whether you are working on conveyor systems, CNC machinery, or packaging lines, this connector offers the flexibility and strength needed for reliable power transmission.
Key Features & Technical Specifications
Adjustable Clamping Design – Easy installation and removal; accommodates shafts of varying diameters within a single coupling size.
High Misalignment Compensation – Handles up to 3° angular, 0.5mm parallel, and 0.3mm axial misalignment, reducing stress on bearings and seals.
Durable Material Options – Constructed from high-grade aluminum alloy or steel, with optional surface treatments like black anodizing for corrosion resistance.
Wide Torque Range – Suitable for light to medium-duty applications, with torque capacities from 5 Nm up to 200 Nm depending on model.
Zero Backlash Operation – Ensures precise motion control, critical for servo systems and encoders.
Vibration Damping – Integrated elastomeric insert (optional) reduces noise and absorbs shock loads.
Customizable Configurations – Available in clamp-type, set-screw type, or keyway versions to meet specific installation needs.

Frequently Asked Questions (FAQ)
Q: What is the maximum shaft size this coupling can accommodate?
A: The standard bore range is 6 mm to 50 mm. Custom sizes up to 80 mm are available upon request.Q: Can this coupling handle high-speed applications?
A: Yes, especially the aluminum version. Maximum rotational speed depends on the bore size; typical limit is 10,000 RPM for smaller sizes.Q: Does the coupling require lubrication?
A: No, it is maintenance-free. The flexible element operates without oil or grease.Q: Is the coupling suitable for use in food processing environments?
A: Standard models are not food-grade. However, we can provide FDA-compliant elastomers and stainless steel options for such applications.Q: How do I select the correct coupling size?
A: Refer to the torque requirement and shaft diameters. Our technical team can help you choose based on your motor power and misalignment conditions.Q: What is the delivery lead time?
A: For standard models, 7–15 working days. Custom orders typically require 15–30 days, depending on complexity.Q: Do you offer samples before bulk purchase?
A: Yes, sample orders are welcomed. We provide a small quantity at a reasonable price for testing.Q: What is the warranty period?
A: We offer a 12-month warranty against manufacturing defects from the date of shipment.
