Hollow output rack and pinion rotary cylinders from Tianjin Uranus Hydraulic Machinery Co., Ltd. feature a unique hollow - output design, providing additional flexibility in system integration. These cylinders use a rack - and - pinion mechanism to convert hydraulic linear motion into rotary motion, with the output being a hollow shaft. The hollow design allows for the passage of cables, pipes, or other components through the output shaft, enabling a more compact and integrated system layout. Made from high - quality materials, these cylinders are designed to withstand high pressures and heavy loads while ensuring smooth and accurate rotary motion. They are suitable for applications where the routing of additional elements through the output is necessary, such as in certain types of robotic arms, specialized machinery, and automated production lines. Our hollow output rack and pinion rotary cylinders offer reliable performance, high - torque capacity, and enhanced functionality.
