Engineering Class Chain products are mostly designed according to each application requirements. There are some chains that follow ISO 606/ANSI B29 guidelines and are usually heavier duty applications. Pitch range is usually 1.654" to 24" or greater.
What is the expected life of a chain?
Chain wear life is usually 1.5% to 2% elongation for Roller and Engineering Class chains. Welded Steel Chains can operate up to 3% elongation after the break-in period is complete.
What lubricant should be used on installed chain?
This depends on the applications. In general, use clean, high quality, non-detergent petroleum based oil. Apply the highest viscosity oil that will properly penetrate in the pin, bushing and barrel.
How can I maximize chain life?
The primary factors that limit chain life are wear, corrosion and fatigue. It is very important to ensure that the proper chain size is selected. A slow drive chain can be selected by either the maximum allowable load (MAL) or using a motor house power table.

Mac Chain sprockets are available with Medium Carbon Steel with custom induction hardening and flame hardening upon request.
