NGGS Series | High-Speed Gearboxes


High-speed gearboxes are applied in special working environments with high speed and technical requirements, such as in the energy industry, chemical industry, petroleum and gas industry, and other fields. Therefore, they have higher requirements in terms of efficiency, vibration, reliability, and other key parameters. The MTG series of high-speed gearboxes were independently developed by NGC, and feature extremely impressive performance in terms of efficiency, vibration, reliability, and cost performance. This series of products have also passed international API certification.
