As a reliable supplier from Hebei Speed Torque Transmission Technology Co., Ltd., we are proud to present our Standard L050 Jaw Coupling, engineered for precise industrial equipment connection and efficient power transmission. With an ISO9001-certified production facility spanning 3,000–5,000 square meters, our factory integrates advanced manufacturing techniques and rigorous quality control to deliver consistent performance. This coupling is designed for applications requiring moderate torque, misalignment compensation, and vibration damping, making it an ideal choice for pumps, gearboxes, conveyors, and general machinery.
The L050 model features a compact, lightweight aluminum hub combined with a durable polyurethane spider insert, providing excellent flexibility and long service life. Its split-hub design simplifies installation and removal, reducing downtime in critical systems. Whether you need standard dimensions or customized bore sizes, our team ensures every coupling meets your exact specifications.
Key Features and Technical Specifications
High Torque Capacity: Suitable for light to medium industrial loads, with rated torque from 2.0 N·m to 4.5 N·m depending on bore/spider selection.
Misalignment Compensation: Accepts angular misalignment up to 1°, parallel misalignment up to 0.38 mm, and axial movement up to 1.6 mm, protecting connected equipment from excessive stress.
Vibration Damping: The polyurethane spider absorbs shock loads and reduces noise, enhancing operational smoothness.
Easy Installation: Split-hub design with clamp screw allows quick mounting without special tools; interchangeable with competitor L050 sizes.
Durable Materials: Aluminum alloy hubs (optional steel hubs available for higher torque) and polyurethane spider (various hardness grades: 92A, 98A).
Wide Operating Temperature: Reliable performance from -30°C to +80°C, suitable for diverse environments.
Customizable Bore: Standard bore range 6 mm – 16 mm; keyway or plain bore options available upon request.

Customer Benefits and Application Advantages
Reduced Maintenance: The plug-in spider design allows quick replacement without moving the hubs, cutting downtime by up to 50% compared to one-piece couplings.
Cost-Effective: Compact size and lightweight reduce shipping costs; the modular design minimizes inventory (same hubs used with different spiders).
Universal Compatibility: Dimensions conform to industry-standard L050 pattern, ensuring easy replacement of similar couplings from other brands.
Enhanced Equipment Life: By absorbing shocks and compensating for misalignment, the coupling protects bearings and seals, extending machine service intervals.
Versatile Use: Ideal for stepper motors, servo motors, encoders, small pumps, and other light-duty rotary drives in automation, packaging, and textile machinery.

Frequently Asked Questions (FAQ)
Q: What is the maximum torque the L050 coupling can handle?
A: The L050 coupling has a rated torque up to 4.5 N·m, depending on bore size and spider hardness. For higher torque, please consider our L075 or L090 models.Q: Can I get a coupling with a custom bore diameter or keyway?
A: Yes, we offer customizable bore sizes within the 6–16 mm range. Keyways, set screws, or plain bores are available upon request. Please provide your drawing for quick quotation.Q: How do I choose the right spider hardness?
A: Standard polyurethane spider is Shore 92A for general use; 98A is recommended for higher torque or less damping. Contact our sales team for application-specific advice.Q: Is this coupling suitable for servo motor applications?
A: Yes, the L050 is commonly used with small servo motors and stepper motors due to its low inertia and good misalignment tolerance. For high-precision applications, we recommend zero-backlash variants (e.g., L050 with urethane spider).Q: What is the operating temperature range?
A: Standard polyurethane spider works from -30°C to +80°C. For extreme temperatures, we can supply Hytrel or other elastomers upon request.Q: Do you provide samples before bulk order?
A: Absolutely. We accept sample orders to evaluate fit and performance. Sample shipping cost is negotiable based on quantity.Q: What is the typical lead time for standard L050 couplings?
A: For stock sizes, lead time is 3–5 working days. Customized versions take 7–15 days depending on complexity.Q: How do I install the L050 coupling correctly?
A: Simply slide the hubs onto the shafts, tighten the clamp screws, and insert the spider. Ensure shafts are aligned within recommended misalignment limits. Installation instructions and videos are available upon request.
