Maple Ace Nickel Plated Roller Chains are developed to offer good wear and corrosion resistance. If your application may involve contact with food, please be aware that Nickel Plated Chains are not suitable. All Maple Ace Chains are Shot-peened, Pre-loaded, Pre-lubricated, Wear-Resistant, and Fatigue Resistant. Higher tensile strength for superior impact resistance. Heat treatment to achieve ideal hardness. Every package contains a 10-feet chain and 2 connecting links. Additional connecting and offset links can be bought separately at our store. The chain can be cut to desired length using a Chain Breaker. - Specification: Item 40-1NP, ANSI Chain number 40-1NP, BS/ISO Chain number 08A-1NP, Chain Length 10 ft, Number of Links 239L, Number of Strands 1, Chain Pitch Metric 12.7 mm, Chain Pitch Inch 0.5 in, Roller diameter d1 max Metric 7.95 mm, Roller diameter d1 max Inch 0.31 in, Width between inner plates b1 min Metric 7.85 mm, Width between inner plates b1 min, Inch 0.31 in, Pin diameter d2 max Metric 3.96 mm, Pin diameter d2 max Inch 0.16 in, Pin length L max Metric 16.6 mm, Pin length L max Inch 0.65 in, Pin length Lc max Metric 17.80 mm, Pin length Lc max Inch 0.70 in, Plate height h2 max Metric 12.00 mm, Plate height h2 max Inch 0.47 in, Plate thickness T max Metric 1.5 mm, Plate thickness T max Inch 0.06 in, Ultimate Tensile Strength Q min 14.1 kN, Average Tensile Strength Q0 17.5 kN, Weight (kg/m) 0.62 kg, Weight (lbs/ft) 0.42 lbs, Material Carbon/Alloy Steel Nickel-plated, - Interchange: - Application:
