About SC Gear Precision

Company Profile

Taiwan Precision Gear Factory Leader, No. 1 in the market share of large machine tool gears.

Shiuh Cheng Precision Gear Co., Ltd. was founded in 1994 and specializes in the design and manufacture of medium- and large-size industrial precision gears, speed-increasing and reduction gearboxes, and custom power-transmission components. The company builds on German RENK gear-manufacturing know-how and the founder’s 11 years of hands-on production experience at Formosa Heavy Industries.
Since its establishment, SC Gear has continuously invested in German precision gear-cutting and grinding equipment. Its manufacturing scope covers external and internal gears, spur gears, helical gears, double-helical gears, gear shafts, and special tooth profiles for machine tools, steel, petrochemical, cement, power generation, marine, railway, defense, and other heavy industrial applications.


Development Milestones

Before 1994|Foundation in Gear Manufacturing

Before establishing SC Gear, the founder accumulated 11 years of hands-on gear manufacturing experience in the production department of Formosa Heavy Industries, building practical expertise in materials, heat treatment, gear machining, and production management.

1994|SC Gear Established

SC Gear Precision Gears Co., Ltd. was officially established and introduced a German HÖFLER BHS 1000 generating gear grinding machine, establishing its high-precision ground gear manufacturing capabilities and laying the foundation for its technical focus on precision gear grinding.

2004|HÖFLER RAPID Profile Grinding Technology Introduced

SC Gear introduced Taiwan’s first HÖFLER RAPID 1500 profile gear grinding machine, expanding its capabilities for high-precision, large-module, special-profile, and custom gears. From the same year onward, the company continued to strengthen its role as a supplier to the machine tool industry, providing precision transmission gears for vertical lathes, horizontal boring and milling machines, presses, and other medium- and large-size machine tools.

2009|Relocation to a New Plant and Expansion of Large-Gear Manufacturing Capacity

In response to the growing market demand for large precision gears, SC Gear relocated to a new plant at No. 53-1, Meishan Road, Niaosong District, Kaohsiung City, expanding its production space and manufacturing capacity. The company also introduced a German GLEASON-PFAUTER P2000/2400 large gear grinding machine, further strengthening its large precision gear grinding capabilities and enabling the production of larger-diameter, high-precision gears.

2016|Entry into the Defense Industry Supply Chain

SC Gear began supplying high-precision gears and critical transmission components for defense applications, gradually building manufacturing experience in radar systems, turret rotation mechanisms, and large gear bearings.

2018|Second Plant Expanded as a Gearbox Assembly Base

As the number of large-gear machining machines and gearbox overhaul projects increased, SC Gear expanded its second plant for gearbox assembly, coating operations, and warehousing. A large paint-curing facility was also introduced to enhance its overall assembly and surface finishing capabilities.

2020|GLEASON-PFAUTER Large Hobbing Machine Introduced

To strengthen its capabilities for large external gears, internal gears, and special gear milling, SC Gear introduced a German GLEASON-PFAUTER P2400/2800 large hobbing machine, further completing its medium- and large-size gear manufacturing processes.

2022|Development and Mass Production of Military Precision Gear Bearings

By combining its precision machine-tool gear manufacturing experience with industry-academia collaboration resources, SC Gear completed the development and mass production of military precision gear bearings for turret, radar, and related rotating systems.

Ongoing|Continuous Expansion of Medium- and Large-Size Precision Gear Capabilities

SC Gear continues to invest in HÖFLER RAPID series and GLEASON-PFAUTER equipment while expanding its software and hardware capabilities for internal gear grinding, cycloidal gear grinding, and HIRTH face gearing to meet the high-precision and customization requirements of various industries.

Core Manufacturing Capabilities

  • Maximum external gear diameter up to Ø3,200 mm
  • Minimum internal gear diameter down to Ø100 mm
  • Module range: 1–50
  • Cycloidal gears up to Ø800 mm
  • HIRTH face gears up to Ø2,000 mm
  • Spur gears, helical gears, double-helical gears, internal gears, gear shafts, and special gears
  • DIN 6 / JIS 2 for general industrial requirements; DIN 5 / JIS 1 to DIN 4 / JIS 0 subject to workpiece and project conditions
  • Large-gear reverse engineering, precision measurement, gear repair, gearbox overhaul, and OEM replacement manufacturing

Capability note: Maximum diameter, module range, and highest accuracy represent overall capabilities under different workpiece and process conditions. They do not mean that every gear can achieve all maximum specifications simultaneously. Actual manufacturability depends on drawings, tooth count, face width, helix angle, material, heat treatment, component structure, and inspection requirements.

Industry Applications and Experience

SC Gear products and services are used in machine tools, steel, petrochemical, rubber and plastics, cement, printing, packaging, power generation, marine, railway, and defense applications. The company also has project or supply experience associated with major Taiwanese industrial and public-sector organizations.

For mining, wind power, robotics, automation, and other emerging applications, SC Gear evaluates each project according to drawings, load, speed, operating environment, and quality-documentation requirements.

Quality and Partnership Philosophy

SC Gear follows a practical, evidence-based approach to manufacturing and emphasizes gear accuracy, process stability, inspection quality, and dependable delivery. The company is certified to ISO 9001 and continues to invest in advanced equipment, manufacturing technology, and quality management to support medium- and large-size precision gears, gearboxes, and custom transmission solutions.
