Diamond Simplex, Duplex Chains and Chain Locks
Manish Bearing Enterprises is an authorised distributor of TIDC Diamond Industrial Chains, supplying industrial roller chains and related power transmission products for manufacturing plants, OEMs, workshops and industrial maintenance teams.
We assist customers looking for Diamond simplex chains, duplex chains, triplex chains and chain locks for industrial power transmission and machinery applications. Whether you require a complete roller chain or a compatible connecting link for an existing chain, our team can help identify the correct specification based on your equipment requirements.
Diamond industrial chains are manufactured by TIDC Industrial Chains Division, part of Tube Investments of India Limited and the Murugappa Group. Its industrial chain portfolio includes standard roller chains, attachment chains, double-pitch chains, conveyor chains and specialised chain designs.
Diamond Simplex Roller Chains
A simplex chain is a single-strand roller chain consisting of one row of chain links. It is commonly used to transmit mechanical power between sprockets in industrial machinery.
Diamond simplex chains are suitable for a wide range of power transmission applications, depending on the chain series, dimensions, load and operating conditions.
Applications of Simplex Chains
- Industrial machinery and power transmission drives
- Electric motor-driven equipment
- Packaging and production machinery
- Conveyor and material-handling systems
- Agricultural machinery
- Textile and processing equipment
- General engineering applications
When selecting a simplex roller chain, confirm the pitch, roller diameter, inner width, chain length and applicable dimensional standard. The chain must also be compatible with the sprockets and operating conditions.
Diamond Duplex Roller Chains
A duplex chain is a double-strand roller chain with two parallel rows of links. Compared with a simplex chain of the same pitch and comparable design, a duplex chain can transmit greater power under suitable operating conditions.
Duplex chains are used where a single-strand chain may not provide the required load or power transmission capacity within the available equipment arrangement.
Applications of Duplex Chains
- Industrial power transmission systems
- Heavy-duty machinery drives
- Manufacturing and processing equipment
- Selected conveyor and material-handling systems
- Agricultural and industrial machinery
- Equipment requiring a double-strand roller chain arrangement
Choosing between simplex and duplex chains requires consideration of transmitted power, sprocket speed, shock loading, lubrication, alignment and available space. A duplex chain should not be treated as a direct substitute without verifying the equipment design.
Diamond Triplex Roller Chains
A triplex chain has three parallel rows of roller-chain links. It is used in selected applications requiring higher power transmission capacity than a single- or double-strand arrangement can provide.
Triplex chains may be suitable for demanding industrial drives, subject to the manufacturer's load ratings and the machinery's design requirements.
For simplex, duplex and triplex chains, ensure that the chain and sprocket tooth configuration, pitch and strand arrangement are compatible.
What Is a Chain Lock or Connecting Link?
A chain lock, commonly called a connecting link or master link, is used to join the ends of a compatible roller chain. It allows the chain to be assembled or disconnected for installation and maintenance.
Connecting links must match the chain's series, pitch, inner width, strand count and construction. A simplex connecting link is not interchangeable with a duplex or triplex connecting link unless specifically designed for that chain configuration.
Types of Roller Chain Connecting Links
- Simplex Connecting Links: For compatible single-strand roller chains.
- Duplex Connecting Links: For compatible double-strand roller chains.
- Triplex Connecting Links: For compatible triple-strand roller chains.
- Spring-Clip Connecting Links: Used on suitable chain designs where the manufacturer specifies a clip-type fastening arrangement.
- Rivet-Type Connecting Links: Used in compatible chain arrangements where a more permanent connection is specified.
The correct connecting link depends on the chain manufacturer's design and application. Always follow the manufacturer's installation instructions and use the specified retaining components.
Common Industrial Roller Chain Sizes
Industrial roller chains are manufactured to different dimensional standards, including metric-based European series and inch-based American series. Customers frequently enquire using a chain number or pitch measurement.
- European Series: Examples include 06B, 08B, 10B, 12B, 16B and 20B, with strand configurations depending on the series.
- American Series: Examples include ANSI #25, #35, #40, #50, #60, #80 and #100.
- Simplex Chains: Single-strand configurations, often identified with a -1 suffix in relevant designation systems.
- Duplex Chains: Double-strand configurations, often identified with a -2 suffix in relevant designation systems.
- Triplex Chains: Triple-strand configurations, often identified with a -3 suffix in relevant designation systems.
Important: These are examples of common chain designations, not a confirmation of current stock. Chain numbering and suffix conventions vary by standard and manufacturer. Confirm the complete chain designation and dimensions before ordering.
How to Select the Correct Diamond Chain and Connecting Link
To identify the appropriate Diamond simplex chain, duplex chain or chain lock, provide the following details wherever possible:
- Existing chain number or manufacturer marking
- Chain pitch and relevant dimensions
- Number of strands: simplex, duplex or triplex
- Roller diameter and inner width, where applicable
- Required chain length or number of links
- Connecting link or master link requirement
- Sprocket details and equipment application
- Operating speed, load and lubrication conditions
If the chain number is unavailable, clear photographs and measurements can help with initial identification. Final selection should be checked against the manufacturer's catalogue and equipment requirements.

Frequently Asked Questions
1. What is the difference between simplex and duplex chains?
A simplex chain has one row of links, while a duplex chain has two parallel rows. A duplex chain can transmit greater power than a comparable simplex chain under suitable conditions, but the correct selection depends on the manufacturer's ratings and equipment design.
2. What is a chain lock?
A chain lock, also called a connecting link or master link, joins the ends of a compatible roller chain. It must match the chain's pitch, series, width and number of strands.
3. Can I use a simplex connecting link on a duplex chain?
No. A standard simplex connecting link is designed for a single-strand chain. A duplex chain requires a compatible double-strand connecting link specified for that chain.
4. Which Diamond roller chain sizes are available?
Diamond industrial chains are offered in different series and dimensions. Availability depends on the complete chain designation, strand configuration and quantity required.
5. How can I identify the correct chain lock?
Provide the existing chain number, pitch, strand count and relevant dimensions. Photographs of the chain and its markings can also help with initial identification.
6. Where can I buy Diamond simplex and duplex chains in New Delhi?
