The company is located in Huangtu Town, Jiangyin City, Jiangsu Province, with very convenient transportation. The company has mature technical conditions and advanced equipment. Relying on exquisite forging, heat treatment and precision processing techniques, we can provide high-load-bearing, high-strength and long-life transmission solutions for construction machinery, medical equipment, intelligent warehousing, photovoltaic industry, port machinery, industrial robots, environmental protection equipment and other fields.
The company is equipped with advanced testing equipment and a complete quality control system. The products have a complete traceability from raw material selection to final product delivery, meeting domestic and international industry standards. The company always adheres to the business philosophy of "quality first, mutual cooperation", providing high-quality services and reliable products to new and old customers.
From a single bearing to complete rotary transmission systems, our metrics reflect our commitment to precision, reliability, and customer satisfaction across every project we undertake.
From single-row ball slewing rings to heavy-duty three-row roller bearings, every product is manufactured using exquisite forging, heat treatment, and precision grinding to deliver uncompromising load capacity and service life.
Manchen slewing ring bearings are engineered to operate under extreme axial, radial, and moment loads, making them indispensable in the most demanding rotary applications worldwide.
Excavators, cranes, concrete pumps, and piling rigs rely on our high-load slewing rings for reliable 360° rotation under dynamic loads.
Ship-to-shore cranes, reach stackers, and harbor mobile cranes demand the highest fatigue resistance—our bearings deliver exactly that.
Collaborative robots and articulated arm systems require ultra-precise low-friction rotation. Our precision-ground races ensure micron-level accuracy.
Solar tracker platforms need corrosion-resistant, weather-proof slewing drives to maintain optimal panel angles across decades of field operation.
CT scanners, surgical robots, and imaging systems demand whisper-quiet, high-precision rotation with zero backlash—a hallmark of Manchen quality.
Automated storage and retrieval systems (AS/RS) and AGV turntables benefit from our compact, maintenance-free slewing ring solutions.
Waste treatment machinery, wind turbine yaw systems, and water treatment platforms operate continuously—our bearings are built to match.
Metallurgical equipment, offshore platforms, and mining machinery place extreme demands on slewing components. We engineer for the toughest conditions.
Built on a foundation of engineering expertise, manufacturing integrity, and customer-first service, Manchen delivers a complete transmission solution that goes far beyond a standard bearing supplier.
From raw material forging to final surface treatment and packaging, every stage of production takes place under our roof. This end-to-end control eliminates supply chain risk, accelerates lead times, and ensures every bearing that leaves our facility meets exact dimensional tolerances. Our advanced CNC turning centers, gear hobbing machines, and raceway grinding equipment operate under strict process controls, giving customers complete confidence in repeatability.
Our engineering team continuously invests in material science, heat treatment optimization, and computational fatigue modeling to push product performance boundaries.
100% traceability from raw material batch to finished product, with documented inspection records at every critical process stage — meeting both domestic and international standards.
We work closely with engineers and procurement teams to develop bespoke solutions — custom tooth profiles, bore diameters, sealing configurations, and surface coatings available on request.
