Product Features
ZL (LZ) Type Elastic Column Pin Toothed Coupling
The ZL (LZ) type elastic column pin toothed coupling uses several column pins made of non-metallic materials, which are placed in the mating holes between the two halves of the coupling and the inner surface of the outer ring. The coupling is connected by transmitting torque through the column pins. This coupling has the following characteristics:
- ⚙️ Large Transmitted Torque: For the same torque, the rotation diameter is mostly smaller than that of the gear coupling, with a smaller volume and lighter weight, which can partially replace the gear coupling.
- 🔩 Simple Structure: Compared with gear couplings, it has a simple structure, fewer components, and is easier to manufacture without the need for gear machining equipment.
- 🛠️ Easy to Maintain & Long Service Life: The nylon column pins can be replaced by simply removing the baffle, ensuring low maintenance effort and extended service life.
Nylon column pins are self-lubricating materials that do not require lubrication, which not only saves lubricating oil but also purifies the working environment.

Frequently Asked Questions
What is the ZL (LZ) type elastic column pin toothed coupling?
The ZL (LZ) type elastic column pin toothed coupling is a mechanical coupling that uses non-metallic column pins placed in mating holes between two coupling halves and the inner surface of an outer ring. It transmits torque through these column pins, offering a compact, lightweight, and durable connection solution.
Can the ZL (LZ) coupling replace a gear coupling?
Yes. For the same transmitted torque, the ZL (LZ) type coupling typically has a smaller rotation diameter, reduced volume, and lighter weight compared to gear couplings, making it a viable partial replacement in many industrial applications.
Does the ZL (LZ) type coupling require lubrication?
No. The nylon column pins used in this coupling are made of self-lubricating materials, which means no lubrication is required during operation. This reduces maintenance costs and keeps the working environment clean.
How do you replace the nylon column pins?
Replacing the nylon column pins is straightforward — simply remove the baffle to access and replace the pins. This simple maintenance process contributes to the coupling's long service life and low downtime.
What are the main advantages of the ZL (LZ) coupling over gear couplings?
The ZL (LZ) coupling offers several advantages over gear couplings: a simpler structure with fewer components, no need for specialized gear machining equipment during manufacturing, no lubrication requirement, easier maintenance, and a more compact and lightweight design for equivalent torque transmission.
What materials are the column pins made of in the ZL (LZ) coupling?
The column pins are made of non-metallic materials, specifically nylon. Nylon is chosen for its self-lubricating properties, durability, and ability to absorb minor misalignments and vibrations, making it ideal for flexible coupling applications.
