About the Factory
Established in 1993
Zhejiang Cheering Sewing Machine Co., Ltd. was established in 1993. It is a National High-Tech Enterprise and recognized as a "Hidden Champion" in China's manufacturing sector.
We are a true factory, not a trading company. Our 40,000㎡ facility in Lishui, Zhejiang, houses a complete production chain from coil winding to final assembly. We have manufactured over 3.2 million direct-drive sewing machine motors and exported to 30+ countries.
R&D capabilities
Our R&D capabilities include a Provincial High-Tech Center, a Postdoctoral Workstation, and a High-Skilled Talent Innovation Studio. We hold over 90 national patents (including 4 invention patents) and 10 software copyrights. All products are CE and 3C certified.
2025 Milestone: At the Las Vegas International Hardware Fair, Qianlin's gearless technology caught the attention of U.S. buyers, who placed an immediate order for 1,500 units. That's the kind of trust we bring to every product.
Key Features
Servo Motor for Singer Sewing Machine
77# QLS-22-550D
550W Rated Power - Handles heavy fabrics, multi-layer denim, leather, and upholstery without bogging down.
