Functions of Roller Chains
In general, roller chains have four key functions:
- To move materials or objects from one location to another
- To transmit power
- To ensure that an action occurs consistently after the previous action over a period of time; i.e. synchronization
- To shift the direction of motion from linear to rotary
Roller chains have significant advantages over belt drives for these functions, as they have very little slippage or stretching across the chains even with a heavy load and are incredibly efficient and long-wearing. Our roller chains offer exceptional strength and durability, thanks to our effective heat treatments and 100% lubrication techniques. Roller chains are exceptional for use in a high-stress environment as they will hold up under even the most difficult conditions such as high and low temperature, or start-stop action usage. Regardless of industry, roller chains are necessary to keep operations running smoothly in various light and heavy-duty applications. By investing in quality roller chains for your day-to-day machinery, you are more likely to enjoy consistent and steady business. These roller chains also have a virtually unlimited shelf life as long as they are stored and maintained in the proper environment.
Sizes of Roller Chains
As you can see above in the roller chain size charts, there is a wide range of sizes that are available in this versatile chain. Single and multiple-strand roller chains are available, with different weight and tensile strength ratings based on the manufacturing requirements for their particular use. Since chains are used as a drive and as part of a conveyor system, the range of sizes can be quite significant. Smaller pitch chains are often found in light to moderate load applications while larger pitch chains are used in heavier load applications.
Roller chain sizes are standardized according to ANSI/ASME or ISO British standards, which are meant to provide interchangeability of design and dimensions for chains, sprockets, and attachments. Fortunately, you will find a wide range of options available at PEERChain.com. Before purchasing your very own roller chain, it is crucial to determine which size component will best suit your operational needs. If you aren’t sure which roller chain will work best for your applications, simply connect with one of our friendly experts.
Roller chain specification includes key values for:
- Size
- Pitch
- Roller Width and Diameter
- Average Ultimate Tensile Strength
- Sizes for ANSI/ASME standard roller chains range from 25 to 240.
Guide To Roller Chain Chart Size: What You Need to Know
Roller chains are essential components in countless industrial and mechanical applications, offering reliable performance for a variety of functions. They excel in moving materials, transmitting power, synchronizing sequential actions, and converting motion from linear to rotary. Unlike belt drives, roller chains provide minimal slippage, superior efficiency, and long-lasting durability, even under heavy loads or in high-stress environments. By understanding these product benefits, you can confidently select a roller chain built to handle your operational demands:
Functions of Roller Chains
- Material Movement: Efficiently transport objects or materials.
- Power Transmission: Reliably transfer power to moving parts.
- Synchronization: Maintain consistent action in timed sequences.
- Motion Conversion: Seamlessly shift motion from linear to rotary.
Roller Chain Sizes and Applications
- Smaller Pitch Chains: Ideal for light to moderate loads.
- Larger Pitch Chains: Built for heavy-duty applications.
- Single and Multi-Strand Options: Versatility to meet specific operational needs.
Strength That Matters
- Tensile Strength: Measures the one-time load a chain can withstand before breaking.
- Fatigue Strength: Indicates a chain's ability to endure continuous use over time without failing.
