Roller chains are essential components in power transmission systems, widely used in various industries such as automotive, manufacturing, and agriculture. They consist of a series of short cylindrical rollers held together by side links and are designed to engage with sprockets to transmit mechanical power efficiently. With a robust construction, roller chains offer durability, high strength, and reliability in demanding applications. Our roller chains are manufactured to international standards, ensuring optimal performance and longevity.
Our roller chains are available in multiple series, each designed for specific load capacities and environmental conditions. Below is a comprehensive table outlining the key parameters for our standard roller chain offerings.
| Chain Series | Pitch (inches) | Roller Diameter (inches) | Average Ultimate Strength (lbs) | Weight per Foot (lbs) | Max Recommended Speed (RPM) |
|---|---|---|---|---|---|
| ANSI 25 | 0.25 | 0.130 | 600 | 0.08 | 5000 |
| ANSI 35 | 0.375 | 0.200 | 1400 | 0.21 | 4000 |
| ANSI 40 | 0.5 | 0.312 | 3100 | 0.45 | 3500 |
| ANSI 50 | 0.625 | 0.400 | 4800 | 0.70 | 3000 |
| ANSI 60 | 0.75 | 0.469 | 7100 | 1.00 | 2500 |
| ANSI 80 | 1.0 | 0.625 | 12000 | 1.60 | 2000 |
In addition to standard ANSI series, we offer metric roller chains with pitches ranging from 6mm to 50mm, catering to global machinery specifications. All our chains undergo rigorous testing for hardness, wear resistance, and fatigue life to meet ISO 606 standards.
Roller chains are versatile and used in numerous applications, including:
What materials are used in your roller chains?
Our roller chains are primarily made from high-carbon steel or alloy steel, with options for stainless steel or nickel plating for corrosive environments. Some models feature heat treatment processes like carburizing to enhance surface hardness.
How do I determine the correct chain size for my application?
To select the right chain size, calculate the required pitch based on the sprocket teeth, load capacity, and speed. Refer to our product parameter table for strength ratings and consult engineering guidelines for torque and tension requirements. We provide sizing tools and support for custom queries.
What maintenance is required for roller chains?
Regular lubrication is crucial to reduce wear and extend chain life. Use high-quality chain lubricants and inspect for signs of elongation, corrosion, or damage. Clean chains periodically in dirty environments, and replace them if elongation exceeds 3% of the original length.
Can roller chains be used in high-temperature environments?
Yes, we offer specialized chains with heat-resistant materials and coatings that withstand temperatures up to 600°F (315°C). However, performance may vary, so it's essential to consult our technical datasheets for specific high-temperature ratings.
What is the difference between standard and heavy-duty roller chains?
Heavy-duty roller chains have thicker side plates, larger rollers, and higher tensile strength compared to standard chains. They are designed for applications with shock loads, high torque, or abrasive conditions, such as in mining or construction equipment.
How do I install a roller chain properly?
Ensure the sprockets are aligned and parallel. Use a chain breaker tool to adjust the length, and connect links with a master link or connecting pin. Apply tension according to manufacturer specifications, avoiding over-tightening, and perform a test run to check for smooth operation.
What certifications do your roller chains have?
Our products comply with ISO 9001 quality management standards and are certified to meet ANSI/ASME B29.1 and ISO 606 specifications. We also provide test reports for tensile strength and durability upon request.
Can you customize roller chains for specific needs?
Absolutely. We offer customizations in length, attachment links, coatings, and materials. Provide your requirements, and our engineering team will design chains tailored to your application, including OEM replacements.
