As a professional manufacturer based in Luoyang, Henan, China, Henan San Kuang Machinery Technology Co., Ltd. specializes in producing high-quality couplings designed specifically for critical machinery applications. Our coupling solutions come with a 2-year warranty and a comprehensive Mill Test Report (MTR) for every unit, ensuring complete material traceability and reliable performance. With a factory spanning 10,000–30,000 square meters and a dedicated team of 51–100 employees, we integrate advanced manufacturing processes and strict quality control to deliver couplings that meet the rigorous demands of industries such as power generation, petrochemical, mining, and marine. Our annual export value of US$2.5–5 million reflects our commitment to serving global markets, including North America, South America, Europe, Southeast Asia, Africa, and Oceania.
This coupling is engineered for heavy-duty rotating equipment where downtime is not an option. Below we detail its key features, technical specifications, and the direct benefits it brings to your operation.
Key Features and Technical Specifications
- Robust Material Selection: Manufactured from high-grade alloy steel, stainless steel, or ductile iron – all sourced from certified mills. Each batch is accompanied by a Mill Test Report for full chemical and mechanical property verification.
- High Torque and Misalignment Capacity: Designed to transmit high torque (up to 500,000 Nm) while accommodating angular, parallel, and axial misalignments, protecting connected equipment from excessive loads.
- Precision Engineering: Machined with CNC equipment to achieve tight tolerances (ISO IT6–IT8), ensuring smooth operation and extended service life under continuous duty.
- 2-Year Warranty: Every coupling is backed by a comprehensive 2-year warranty covering material defects and workmanship, giving you peace of mind for critical applications.
- Documentation Package: In addition to the MTR, we can provide dimensional inspection reports, NDT reports (ultrasonic or MPI), and material certificates upon request.
- Versatile Design Options: Available in flexible disc, gear, grid, and elastomeric types to suit specific application requirements. Custom bore sizes, keyways, and special coatings are available.
- Surface Protection: Standard paint, phosphating, hot-dip galvanizing, or special anti-corrosion coatings for harsh environments.
