Premier Series #120-3 roller chain is a premium ANSI 120-3 triplex chain that is manufactured dimensionally to ANSI B29.1 specifications. The basic function of a roller chain is to transport mechanical power to the highest degree possible, the Premier Series selection of roller chains set the bar for this degree by providing superior strength, performance, and precision. Made from high-strength premium-grade steel, high-precision components that have been individually heat-treated shot-peened, and inspected for quality assurance, then assembled by being precisely riveted together this chain is manufactured to last.

Premier Series 120-3 Roller Chain Features

	High-Strength heat-treated solid rollers to keep the cylindrical shape of the roller long term and for optimal chain performance.
	Cold-Forged Solid Bushings made to precise roundness for greater strength and performance versus the standard split-bushing design.
	Heat-Treated Parts (including pins) for added strength and surface hardness that results in longer working life.
	Shot Peened Parts to alleviate stress concentrations and increase strength.
	Wide-Waste Side-Plates for added fatigue resistance and reduction in progressive elongation.
	Factory Preloading is the final process that results in a great reduction of stretch and ensures all components are properly aligned.

More specifically #120-3 triple strand roller chain has a 1-1/2" (1.50") pitch and is the ninth largest-sized roller chain in the ANSI lineup. Interestingly enough, you can always determine the pitch value of an ANSI chain by dividing the first number in the chain size by 8, twelve divided by eight = 1.50". Applications for #120-3 roller chain include demanding heavy-duty plant machinery, construction machinery, mining, oil field, conveying and drive, as well as many more applications! The Premier Series 120-3 triple strand chain offers an industry-leading service life and dependability, with a high tensile strength of 117,000 LBS and a 17,080 LBS maximum working load this chain can be run in even toughest 120-3 chain applications. Something important to note about the two strength measurements is that tensile strength is the load in which the chain can be expected to break under certain conditions and working load is the maximum safe operating force for the day-to-day operation and is calculated taking many variables into consideration. As with any chain, it is imperative to utilize proper lubrication for the application and lubricating techniques, for more information on this visit our roller chain lubrication page.
