Connecting to higher profitability within your business is always a good thing, and coupling chains from czpt Chain will help you get there quickly. These powerful and flexible chains are sure to keep your operation running at peak performance, whether you’re using them for mining, farming or even metal manufacturing processes. Roller chains are the most popular types of chain for a wide range of applications, and our coupling chain will help extend their usability beyond the basics — letting you handle larger loads and more stress without damaging your equipment or running the risk of breakage.

Compact and Powerful

Torque is apportioned over the whole roller chain and all sprocket teeth, and is held at a point close to the outer diameter of the sprockets. This construction and the superior qualities of czpt roller chain combine to make a compact and lightweight coupling.

Safe and Smart

The casing, which revolves with the body of the coupling, has an attractive design. And unlike other couplings, there are no dangerous projecting bolts. Connecting and removing the shafts is simply accomplished using a connecting pin.


1. FCL flexible coupling is widely used for its compact design, easy installation, convenient maintenance, small size and light weight.

2. As long as the relative displacement between shafts are kept within the specified tolerance, couplings will operate the best function and have a longer working life.

3. It’s greatly demanded in medium and miner power transmission system driven by moter, such as speed reducer, hoist, compress, conveyor, spinning and weaving and ball mill.

4.To be plugged in axially,easy assembly,maintenance free Applicable from -40oC to+100℃ temperature can peak up to 120℃.

Double roller chain use GB1243.1-83 which have the Rule on Short pitch transmission precision roller chain

–        Shaft hole keyway type and size conform to GB/T3582-1997 Rules.

–        The structure and size of the shell are selected according to the requirements.

–        Simple structure, Convenient assembly and disassembly, It will have empty stroke when reversal.

–        It is no suitable for Great impact load reverse transmission

1. Applies to flexible drive shaft ,allowing a larger axial radial displacement and displacement.
2.Has a simple structure,easy maintenance .
3.Disassembly easy
4.low noise
5.Transmission efficiency loss,long useful working life.

6.The chain coupling, composed of two-strand roller chains and two sprockets, features simple and compact structure, and high flexibility , power transmission capability and durability. What’s more, the chain coupling allows simple 

connection/disconnection, and the use of the housing enhances safety and durability.

1.Material:Stainless Steel,C45 steel,Aluminum,Rubber and plastic etc.

2.OEM and ODM are available

3.High efficient in transmission

4.Finishing:blacken, phosphate-coat,and oxidation.

5.High quality with better price

6.Different models suitable for your different demands

7. Different models suitable for your different demands

Our Process

Chain Coupling Features:

Chain coupling simple structure, convenient installation and disassembly not need moving the connection of two shafts, compact size, light quality, has the certain compensation ability, the installation precision is not high, reliable operation, long service life, low cost advantages.

What are the benefits of using a chain coupling?

The main benefit of using a chain coupling is its ability to transmit high levels of torque, making it ideal for the highest torque applications. 

Chain couplings have flanges which are linked with duplex roller chains, giving them a high level of strength. 

These couplings are also able to accommodate up to 2 degrees of misalignment, helping to protect surrounding equipment from the effects of misalignment.
