Roller Chain Operating Temperatures

When it comes to roller chain operating temperatures, the standard safe range for carbon steel roller chains is 15°F to 140°F. That said, most carbon roller chains can handle occasional spikes up to 150°F without any major issues. We’ve put together this article to explore roller chain operating temperatures in depth, including solutions for applications that fall outside the recommended range. You’ll find detailed info on how roller chains perform in both high- and low-temperature environments, as well as the temperature limits of roller chain sprockets. If your application involves temperatures below 15°F or above 140°F, it's important to consult with one of our team members to ensure you’re selecting the best chain for your specific needs.

Roller Chain Operating Temperatures Explained

The table provides a clear and simplified visual representation of the standard operating temperature ranges for carbon steel standard roller chains, stainless steel roller chains, and poly-steel (plastic) roller chains. It is always recommended to contact one of our sales consultants when using a roller chain outside the recommended ambient temperature ranges so that we can provide the best solution tailored to your individual application needs.

High Temperature Roller Chain Applications

These applications fall into three temperature ranges: 140°F–300°F, 300°F–390°F, and 390°F–480°F. Use of carbon steel roller chain at temperatures exceeding 480°F is not recommended due to accelerated material degradation. For applications in these higher-temperature scenarios, please contact us for guidance. As an alternative, 304-grade stainless steel roller chain is capable of continuous operation at temperatures up to 752°F with no loss in tensile strength, and up to 1200°F with measurable reductions in both mechanical strength and service life.

140°F to 300°F – Roller Chain can Operate Optimally with Proper Lubrication
300°F to 390°F – Chain Lifespan & Strength is Decreased by 25% Even with Hi-Temp Lube
390°F to 480°F – Chain Lifespan & Strength is Decreased by 50% Even with Hi-Temp Lube

Some common examples of roller chains operating in high-temperature applications include kiln conveyors, ash handling, cement clinker, mining, bakeries, and treating facilities.

What happens if You Use a Roller Chain in high-temperature applications without proper lubricant?

In most scenarios, the following problems occur:

Increased Wear Due to Decreased Hardness
Improper Lubrication Due to Lubricant Deuteration or Carbonization
Stiff Joints and Increased Wear Due to Oxide Scale Formation
Chain Failure Due to Decreased Strength

Low Temperature Roller Chain Applications

Standard roller chains can operate safely at 15°F without the need for a low-temp lubricant or grease. While implementing the use of a low-temperature lube or grease can enable your standard chain to operate in conditions as low as -40°F, it degrades the chain’s strength and lifespan. Refer to the chart for more details! Additionally, we offer a TK Low-Temp Series roller chain, manufactured from specific alloys that follow specific heat-treatment specifications to withstand frigid environments down to -40°F, while giving the same strength and performance as its standard counterpart. Alternatively, 304-grade stainless steel roller chains can operate in temperatures as low as -40°F without degrading strength or lifespan, or down to -200°F with a degradation in both strength and lifespan. Low-temperature brittleness does not occur in austenitic stainless steel. Some common examples of roller chains operating in high-temperature applications include conveyor systems used in freezers or refrigerated environments, as well as outdoor applications in cold climates.

What happens if You Use a Roller Chain in low-temperature applications without proper lubricant?

In most scenarios, the following problems occur:

Decreased Strength Due to Brittle Materials
Lubricant Solidification
Stiff Joints from Frost or Ice

Low Temperature TK Series Roller Chains

TK Series roller chains are capable of operating at -40°F without any issues regarding lifespan. Our premium TK series chains are made from specific steel alloys and come pre-lubricated with a specialized grease that enables low-temperature operation without causing operational issues. It is worth noting that TK series chains are typically made to order, with a lead time, but are also available with attachments and in various chain sizes/ configurations. For additional information or assistance with your high- or low-temperature chain applications, please don't hesitate to contact one of our team members.

Roller Chain Sprocket Operating Temperatures

When evaluating the operating temperature of a roller chain application, the sprockets must also be considered, as they are critical components in power transmission. In most cases, standard-material sprockets are sufficient for the intended application; but we’re including this section to shed light on the sprocket side of the equation for a more complete understanding.

Carbon Steel Sprocket Operating Temperatures

Carbon steel roller chain sprockets are capable of optimal performance at ambient temperatures ranging from -50°F up to 399°F. Moving up the temperature scale, at 400°F and above, carbon steel begins to weaken in small amounts until it reaches 600°F. From 600°F to 800°F, carbon steel sprockets lose roughly 40% of their yield strength. Another aspect to consider is thermal expansion. In high-temperature applications requiring precise control, the thermal expansion of carbon steel should be taken into account.

Stainless Steel Sprocket Operating Temperatures

Stainless steel sprockets are capable of operating in ambient temperatures ranging from -320°F to 750°F without compromising their integrity. Once temperatures surpass 750°F, the material will gradually lose its strength, and the risk of the material becoming sensitized increases, leading to the precipitation of chromium carbides at grain boundaries and a reduction in corrosion resistance. Stainless steel sprockets offer the optimal temperature range compared to any standard roller chain sprocket.

Roller Chain Operating Temperatures Conclusion

In conclusion, we have covered the high-temperature and low-temperature operating ranges of roller chains, as well as the operating temperature ranges of roller chain sprockets. We’ve also reviewed some fundamental solutions / guidelines for roller chain needs in these types of applications. It’s always important to consider strength, thermal expansion, and thermal contraction when operating roller chains and sprockets outside of the safe ambient temperature range of 15°F to 140°F.
