#50 Roller Chain

Our offering of #50 roller chain is manufactured in accordance with American National Standards Institute (ANSI) B29.1 standards dimensionally. The ANSI/ ASA 50 chain specs have represented the same dimensions since 1930, since then improvements to chain design, manufacturing processes, and metallurgy, have produced high-performance precision 50 roller chains that are used today. Though dimensionally the exact same we offer three different quality levels of the #50 roller chain that goes above and beyond the standard strength and performance-wise upgrades. At USA Roller Chain we provide the industry with not only a high-quality component or chain but also a high-quality customer service.

Economy Plus series #50 roller chain uses heat-treated precision components and features a solid roller design for improved performance.
General Duty Plus series roller chain is essentially the same except uses a higher-heat treat thus making it better for high-speed and higher load applications.
Premier Series roller chain uses the highest-strength components that have been heat-treated, shot-peened, and hardened to a maximum. They also implement a solid bushing solid roller (SBR) design and use a premium-grade lubricant for maximum durability, strength, and working life.

We stock a wide range of configurations of #50 roller chain including anti-corrosive, attachment chains, and specialty series.

Corrosion-resistant 50 roller chain is made for applications where corrosion is an issue. depending on the specific application different anti-corrosive roller chain options can be used. We also supply anti-corrosive 50 chain attachments and stainless steel sprockets.

#50 Stainless Steel Roller Chain
#50 Nickle-Plated Roller Chain
#50 Coated Roller Chain

Maintenance-free 50 roller chain is generally utilized in applications where maintaining the roller chain is difficult and or impossible. Also depending on the chain used, in applications that are dusty or dirty. We stock a wide array of problem solver/ maintenance-free chains.

#50 self-lubricating chain:

Self-Lubricating chain utilizes an oil-impregnated sintered bushing to continually disperse lubrication within the chain its self.
#50 O-Ring Roller Chain:

O-Ring chain utilizes o-rings within the chain to keep lubrication in while keeping contaminants out of the chain.
#50 X-Ring Roller Chain:

X-Ring chain is the same concept as the O-Ring chain only with an additional wear resistance factor.
#50 Side Flexing chan is designed with elongated pin-links to create a roller chain that is capable of "bending" around a radius. This chain is also commonly referred to as 50 side-bow roller chain and does run on standard sprockets, we supply this chain in a standard mild-steel as well as stainless steel (50SS-SB) for corrosive and food environments.

Hollow Pin 50 roller chain is manufactured in a unique way that allows for an array of extended pins to pass through the chain, creating an easy "base chain" for many conveying and elevating applications. We stock these chains in standard carbon steel and stainless steel (50SSHP) materials.
