Henan San Kuang Machinery Technology Co., Ltd., established in 2014, is a professional manufacturer of precision transmission components. Our factory spans 10,000–30,000 square meters and employs 51–100 skilled workers, with an annual export value of US$2.5 Million–US$5 Million. We are proud to introduce our Zero Backlash Aluminum Alloy Jaw Flexible Shaft Coupling, specifically engineered for servo motor applications. This coupling eliminates transmission errors, ensures precise motion control, and delivers exceptional durability—making it the ideal choice for demanding automation systems.
Key Features & Technical Specifications
- Zero Backlash Design: Precision-machined jaw profile with pre-loaded elastomeric spider eliminates rotational play, ensuring accurate positioning and repeatability.
- High-Grade Aluminum Alloy: Lightweight yet strong, reduces inertia on servo motors, improving dynamic response and energy efficiency.
- Flexible Spider Insert: Made from durable polyurethane or rubber (optional), absorbs vibration, dampens noise, and compensates for minor misalignment (angular, parallel, and axial).
- Easy Installation: Clamp or set screw style hubs allow quick mounting without disassembly of connected equipment.
- Wide Bore Range: Customizable bore diameters from 6mm to 50mm to fit various servo motor shafts and load shafts.
- High Torque Capacity: Engineered to handle peak torques up to 500 Nm (depending on size), suitable for heavy-duty servo applications.
- Corrosion Resistant: Natural aluminum finish or optional anodized coating for harsh environments.
- Balanced for High Speed: Precision balanced to minimize vibration at high rotational speeds (up to 10,000 RPM).

Frequently Asked Questions
-
Q: What does “zero backlash” mean exactly?
A: Zero backlash means there is no rotational play or clearance between the hub and spider. This ensures instantaneous torque transmission without any lost motion, critical for precise positioning in servo systems. -
Q: Can this coupling compensate for misalignment?
A: Yes, the flexible spider insert allows for angular misalignment up to 1°, parallel misalignment up to 0.2 mm, and axial movement up to 0.5 mm, while maintaining zero backlash. -
Q: What materials are available for the spider?
A: Standard spiders are made of polyurethane (Shore A 80). Optional materials include nitrile rubber, Hytrel, or custom compounds for higher temperature or chemical resistance. -
Q: Do you offer custom bore sizes?
A: Absolutely. We can machine bores to your exact specifications, including keyways, metric or inch dimensions, and special tolerances. -
Q: Is this coupling suitable for high-speed applications?
A: Yes, it is dynamically balanced for speeds up to 10,000 rpm. For higher speeds, we recommend an optional precision balancing service. -
Q: What is the typical lead time?
A: For standard sizes, lead time is 5–7 working days. Custom orders may require 10–15 working days depending on complexity. -
Q: Do you provide technical support for selection?
A: Yes, our engineering team can help you select the correct coupling size based on your torque, speed, shaft diameters, and misalignment conditions. -
Q: What certifications do your products have?
A: Our factory is certified under ISO9001, ISO14000, OHSAS18001, and many other systems. Specific product certifications are available upon request.
