This is a large-module heavy-duty spur gear, professionally engineered to deliver stable performance under low-speed and high-torque operating conditions. Built to withstand heavy loads and continuous operation, it is widely adopted in robust industrial transmission systems that demand outstanding bearing capacity and reliability. All listed dimensions strictly comply with standard ISO tooth profile specifications to guarantee accurate meshing and consistent performance.
Please note that optional special tooth profiles, including full-depth teeth and stub teeth, will come with minor dimensional differences to fit distinct working requirements.
When matched with a rack for linear motion transmission, it must pair with a Module 14 straight rack featuring the identical pressure angle. This matching configuration ensures smooth engagement, minimizes friction and vibration, and prevents abnormal wear or operation errors.
Overall, it is a dependable drive component for heavy industrial machinery and mechanical lifting equipment.
