Welcome to Hebei Speed Torque Transmission Technology Co., Ltd. We are pleased to introduce our premium Stainless Steel Flexible Universal Joint Coupling, specifically engineered for motor flange, gear pump, and spline shaft applications. As an ISO9001 certified manufacturer with over 7 years of experience and an annual export value of US$5-10 million, we deliver reliable coupling solutions that ensure efficient torque transmission and misalignment compensation. Our coupling combines robust stainless steel construction with flexible universal joint design, offering durability and precision for demanding industrial environments.
This coupling is designed to bridge the gap between motor flanges, gear pumps, and spline shafts while accommodating angular, parallel, and axial misalignments. It reduces vibration, noise, and wear on connected equipment, extending overall system life. The stainless steel material provides excellent corrosion resistance, making it suitable for food processing, chemical, pharmaceutical, and marine applications. Key features include high torsional stiffness, easy installation, and low maintenance requirements.
Product Highlights & Technical Specifications
Material Excellence: Made from high-quality stainless steel (304/316 available), offering superior resistance to rust, chemicals, and high temperatures.
Flexible Universal Joint: Allows up to 15 degrees angular misalignment and 5mm parallel misalignment, ensuring smooth power transmission even when shafts are not perfectly aligned.
Versatile Connection: Compatible with motor flange, gear pump shafts, and spline shafts. Custom bore sizes and keyways are available upon request to match your exact equipment.
Anti-vibration Design: Reduced vibration and shock loads protect pumps, motors, and other driven components, minimizing downtime.
Easy Installation: Simple bolt-on design with no special tools required. Can be integrated quickly into existing systems.
Long Service Life: Precision machining and heat treatment ensure consistent performance over thousands of operating hours.
Custom Options: Different lengths, diameters, and surface finishes (polished, passivated) available to meet specific application requirements.

Frequently Asked Questions
Q: What is the maximum torque this coupling can handle?
A: The torque capacity varies based on the bore diameter and overall dimensions. Please provide your operating parameters, and our engineering team will recommend the appropriate size. For standard designs, we can handle torque up to 500 Nm, with custom options for higher values.Q: Can I use this coupling for a spline shaft with non-standard dimensions?
A: Yes, we offer custom machining for both bore diameter and spline profiles. Simply send us your shaft drawing or detailed measurements, and we will manufacture a coupling that fits precisely.Q: Does the stainless steel coupling require any special lubrication?
A: The universal joint portion is pre-lubricated with a high-temperature grease and typically does not require re-lubrication under normal conditions. However, for extreme operating environments or high-speed applications, we recommend periodic maintenance as outlined in the user manual.Q: What is the typical lead time for a custom order?
A: For standard sizes, we can ship within 7-15 working days from the port of Shanghai, Tianjin, or Qingdao. Custom orders usually take 20-30 working days, depending on the complexity. We will confirm the exact lead time after reviewing your specifications.Q: Is this coupling suitable for food-grade applications?
A: Yes, when made with 316 stainless steel and with a polished surface finish, it meets typical food industry hygiene requirements. The material is non-toxic and resistant to corrosion from cleaning agents. Please specify your application when ordering so we can recommend the best option.Q: Can the coupling handle both clockwise and counterclockwise rotation?
A: Absolutely. The universal joint design works symmetrically and can transmit torque in both directions without any modification. It is ideal for reversible motors and pumps.Q: Do you provide samples before mass production?
A: Yes, we offer sample orders for evaluation. The sample cost can be deducted from the full order amount. Please contact our sales team to arrange a sample.Q: How do I install the coupling correctly?
A: Detailed installation instructions are included with each product. In general, ensure that the shafts are aligned as closely as possible within the specified misalignment limits, then tighten the set screws or bolts evenly. We also provide technical support via email or video call if needed.
