About KNGEAR
KNGEAR is a China gearbox manufacturer specializing in industrial gearboxes and custom gear manufacturing, established in 2007. KNGEAR is based in Changzhou, Jiangsu, China. We support new equipment, non-standard drive systems, replacement gearboxes and precision gear projects for demanding industrial applications.
Our work combines application engineering, gear and shaft manufacturing, housing machining, assembly, inspection and project support. Projects are developed from the actual operating duty and machine interfaces rather than catalogue size alone, which is especially important for heavy-duty, custom and replacement gearboxes.
KNGEAR company facts: Founded in 2007 and based in Changzhou, Jiangsu, China, KNGEAR focuses on industrial gearboxes, custom and replacement gearboxes, precision gears and shafts. Production work includes in-workshop gear and shaft machining, gear cutting and grinding, gearbox assembly, painting, inspection and testing. Heat treatment and gearbox housing fabrication/machining are carried out by qualified specialist subcontractors, with hardness records and housing dimensions checked to project requirements.
Buyer verification: manufacturing facilities, machine-specific workshop evidence, inspection/test records and project-specific engineering data are available across this website for supplier evaluation.
Engineering and Manufacturing Focus
KNGEAR focuses on industrial gearboxes where torque, ratio, shaft arrangement, duty cycle, mounting constraints, lubrication, cooling and installation interfaces matter as much as nominal power. Our engineering process is intended to translate these operating requirements into a practical gearbox or gear-manufacturing specification.
Application Engineering
Projects begin with the operating data: input power and speed, required output speed, continuous and peak torque, shaft loads, starts, reversals, operating hours, mounting arrangement and environment.
Gear and Shaft Manufacturing
Manufacturing capability includes in-workshop gear and shaft cutting, precision grinding, dimensional inspection, gearbox assembly, painting and testing. Heat treatment and gearbox housing fabrication/machining are performed by qualified specialist subcontractors to project requirements.
Replacement and Reverse Engineering
For obsolete or unsupported gearboxes, existing drawings, nameplates, samples and installation measurements can be used to recover critical geometry and evaluate a replacement route.
For more detail, see Gear Works, Engineering Services and Repair, Reverse Engineering & Replacement Solutions.
Manufacturing and Workshop
Our production and inspection resources support custom gears, industrial gearboxes and replacement projects from machining through assembly and verification.
Industrial Applications
KNGEAR gearboxes and custom gear projects are used across heavy industrial machinery and process equipment. Our application pages describe the operating conditions and selection considerations for each sector.
- Mining and material handling
- Oil and gas equipment
- Marine and offshore equipment
- Construction equipment
- Plastic and rubber extrusion
- Chemical and process machinery
How We Work
- Application review: operating data, drawings, interfaces and project requirements.
- Engineering definition: ratio, torque, configuration, materials, bearings, lubrication and cooling requirements.
- Manufacturing: gear cutting, machining, heat-treatment coordination, grinding and component production.
- Inspection and assembly: dimensional checks, gear inspection, fits, backlash, assembly and project-specific verification.
- Project support: drawings, technical communication and replacement/retrofit coordination where required.
