Product Description
GFB Rotation Speed Reducer
Product Introduction:
The GFB series rotation speed reducer is the ideal driving equipment for the slewing platforms of wheeled or crawler excavators, rotary drilling rigs, crawler and truck cranes, ship cranes, and various other applications. It delivers highly reliable performance even under the most severe working conditions. Due to its compact structure, it can be directly mounted inside the equipment, significantly saving space and making installation and maintenance highly convenient.
The internal structure of the GFB reducer adopts our company's new technology, making its installation dimensions and main technical parameters nearly identical to the Bosch-Rexroth product. Therefore, it can be used as a direct replacement for imported products. It is also compatible with other similar brands such as Brevini, Tejin, Nachi, and KYB. We provide strong design and customization capabilities, offering consulting services to help customers select the most suitable transmission solution based on their specific needs.
The GFB reducer can be connected to constant or variable hydraulic motors from Bosch-Rexroth, as well as other brands. A spring-loaded, hydraulically released multi-disc parking brake can be installed at the input terminal. The static braking torque matches the input torque of the hydraulic motor (typically 1.5 times greater).
