Product Overview:
 

Rack and pinion sets are the devices that deliver precise motion, even over unlimited lengths. Now a days rack-and-pinion systems offer high dynamic performance and unlimited travel distance. Some include premium gears and actuators with backlash less than 1 arc-min., efficiency to 98.5%, and far more compact sizes than standard servomotor-gear combinations. Some preassembled gear-pinion units can even run true to 10 µm, for safety and smooth motion. Rack and Pinion drives offer constant stiffness over the complete travel length plus good system behavior — for superior control system behavior.
 

Lubrication Is The Key:

Rack-and-pinion sets last longest when properly lubricated. Appropriately greased sets are also most capable of reaching highest rated speed. For many rack and pinion systems, the most common method is an automatic lubrication kit or greasing device.
 

Mounting:

​

Mounting options abound for rack-and-pinion sets. Some racks use special mounting surfaces to ensure accuracy, while others deliver suitable performance even with basic installation. The design’s inherent flexibility can be leveraged for better control: Unlike direct-driving linear motors, rack-and-pinion sets allow adjustments in pinion size, gear ratios, and damping — to stabilize closed-loop control.

Rack-and-pinion sets have lower mass moment of inertia and higher natural frequency and efficiency over ballscrews. There are fewer components to save time during installation. Also, length is unlimited.

​

Applications:
 

Typical rack-and-pinion applications include gantry, transport, and packaging machines that carry from a few pounds up to several tons. Next-generation rack-and-pinion sets are also used in woodworking, high-speed metal cutting, and assembly machines.
