Premier Series #40-2 roller chain is a premium ANSI 40-2 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 40-2 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 which results in a great reduction of stretch and ensures all components are properly aligned.

More specifically #40-2 double roller chain has a 1/2" (0.500") pitch and is the fourth largest sized roller chain in the ANSI lineup. it's commonly used in slow to fast-moving applications that require a high-strength chain with a narrow profile. Applications for #40-2 double strand roller chain include demanding agricultural equipment, plant machinery, conveying and drive applications, and many more! The Premier Series 40-2 chain offers an industry-leading service life and dependability, with a high tensile strength of 8,600 LBS and a 1,400 LBS maximum working load this chain can be run in even the toughest 40-2 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.
