Description

About ANSI #50 Roller Chains

CTS® #50 Roller Chain

Our #50 roller chains adhere to ANSI B29.1 Standards, ensuring complete interchangeability with other ANSI-certified roller chains and proper operation on #50 chain sprockets. Crafted with precision, our roller chains feature high-quality heat-treated, shot-peened, and hardened components, complemented by a factory-applied premium lubricant for optimal performance.

The #50 roller chain (5/8-inch pitch) is one of the most common chain sizes used in agricultural and conveying equipment, frequently found in harvesters, balers, conveyor lines, packaging machinery, automotive production lines, and general industrial drive applications. Offering approximately 30% higher load capacity than the #40 roller chain while being more compact than the ANSI 60 roller chain, it represents a balanced choice for medium-duty operations. The #50 chain featured here complies with ANSI B29.1 standards and is interchangeable with all standard-compliant 5/8-inch pitch sprockets.

Quality Assurance:
ISO9001: 2015 and GB/T24001-2016 / ISO14001: 2015.

#40 Roller Chain VS #50 Roller Chain

The comparison table above lists the key dimensional differences between #40 and #50 chains.

Feature	ANSI #40 Roller Chain	ANSI #50 Roller Chain
Pitch	12.70mm	15.88mm
Inner Width	7.92mm	9.53mm
Pin Diameter	3.96mm	5.08mm

Simply put: the larger the pitch, the higher the load-carrying capacity per link. #40 is suitable for light-load, high-speed applications, while #50 is suited for medium-load, standard operating conditions. For applications requiring greater strength, the #50H heavy-duty series chain is available—featuring thicker link plates and higher tensile strength, while maintaining the same pitch and sprocket compatibility.
