Our premium quality 50 roller chain sprockets utilize a high-grade carbon steel material and follow through with an anti-corrosive black oxide coating and feature hardened teeth (on tooth counts 30 or below). The combination of premium features and precision tolerance manufacturing make these size 50 sprockets a high-quality, reliable, and durable component for any conveyor or drive system. Being manufactured dimensionally in accordance with ANSI B29.1 Standards from the American National Standards Institute means that our sprocket is compatible with any ANSI 50 roller chain and directly replaces out any ANSI 50 sprocket with its equivalent size. We also supply custom bore or complete custom manufactured #50 chain sprockets upon request, in a range of material options ranging from plastic, stainless steel, and even aluminum.
