Tsubaki Pin Gear Drive Unit: Advanced Motion Drive for Large Industrial Equipment
In modern industrial machinery, achieving reliable and efficient motion transmission is critical. The Pin Gear Drive Unit (PDU) from Tsubaki offers an innovative solution designed to replace conventional rack-and-pinion and large gear systems. With its unique design, high torque capability, and flexible installation, the Pin Gear Drive Unit is ideal for heavy-duty industrial applications that require both precision and durability.
This advanced drive system enables smooth motion for both linear and rotational drives, making it suitable for a wide range of industries including steel, automation, infrastructure, and heavy machinery.
What is Pin gear drive unit?
A Pin Gear Drive Unit is a transmission mechanism composed of a pin gear, pin rack, or pin wheel that mesh together to produce motion. Unlike traditional gear systems, the PDU uses a gear with a specialized tooth profile that engages with rollers mounted on the pin rack or pin wheel.
linear motion and rotational motion
This is a transmission part that has the same function as a gear or rack and pinion, and converts rotation into linear motion or rotation into another type of rotational motion by combining a pin-mechanical wheel rack with a dedicated gear. It has been delivered to a variety of devices.

Key Features of the Tsubaki Pin Gear Drive Unit
1. Easy Installation2. High Transmission Torque
The combination of pin gears and rollers ensures excellent load distribution. This enables the system to transmit large torque while maintaining smooth motion, making it ideal for heavy-duty industrial applications.3. Flexible Design for Large Equipment
One of the biggest advantages of the PDU is scalability. By increasing the number of wheel segments, the drive system can be used in large industrial machines and rotating equipment.4. Durable and Wear Resistant
The pin gear teeth are hardened to improve resistance to wear and extend service life. Continuous engagement between the gear teeth and rollers also reduces friction and ensures long-term reliability.5. Corrosion Resistance Options
Tsubaki offers several material options to suit different environments, including:
-
Standard steel type
-
Flexible type
-
Stainless steel series for corrosive environments
These options allow the drive unit to operate effectively even in harsh industrial conditions.
Pin gear drive unit Structure
The unit consists of a pin rack or pin wheel and pin gear.
The basic structure of a pin rack/pin wheel is almost the same as that of a chain, with bushings press fit into a frame of any shape and rollers inserted.
