DUROCHAIN Premium 16B-4 Roller Chain 16B-4 Chain

16B-4 roller chain has a 25.4mm pitch and is manufactured from high-quality carbon steel that meets ISO and British Standards. DUROCHAIN isn't just another generic private-label chain like countless other brands that flood the market. Increased performance and extended wear life allow DUROCHAIN 16B-4 to outshine the competition. We spent years gathering feedback from end users and researching the most cutting-edge manufacturing processes so that we could bring a true Tier 1 premium quality roller chain to the market. Our high-performance 16B-4 chain boasts a staggering 30,000 kgs (66,138 lbs) minimum breaking load, along with the ability to transmit energy at the utmost levels of efficiency. During the R&D process, we discerned multiple shortcomings of traditional 16B-4 roller chain and embarked on a journey to develop a roller chain that directly addresses these downfalls. With boots-on-the-ground, we analyzed how each different application affected 16B-4 roller chain's overall performance and wear life. Using this data, we began designing a 16B-4 roller chain that significantly increases productivity by decreasing downtime across multiple industries and their respective applications. At this point, you're probably thinking, well that sounds great and all, but what actually makes DUROCHAIN 16B-4 so different than the chain that I'm currently using? Well, I'll be happy to tell you! DUROCHAIN 16B-4 is proudly manufactured with precision solid bushings, solid rollers, hardened pins, and beautiful quad-staked rivets. DUROCHAIN is sure to be the best looking roller chain you've ever laid eyes on! Individual components make their way through a multitude of innovative heat treatment and shot-peening processes to unlock each individual component's true potential. The chain is then expertly assembled and stretched to 40% of its rated breaking load; thus reducing initial stretching and overall fatigue of the chain. This means the customer can get up and running fast and maintain the peace of mind that they are running a quality chain in their application. This Quad-Strand DUROCHAIN 16B-4 roller chain consists of four strands of 16B-1 roller chain, all connected by our special pins and riveted together by our rock-solid quad-stake riveting process. Our quad-staked rivets will hold on to the chain's side plates harder than a baby holds on to it's beloved rattle! This dramatically reduces the chances of premature failure caused by the inferior two-stake rivets that have unfortunately become industry standard. The rivets are often regarded as the most crucial part of a roller chain because if a rivet fails, the chain is almost guaranteed to fall apart! You can have the best chain components available, but if the rivet is poor, the chain will prematurely fail. Our state-of-the-art DUROCHAIN 16B-4 roller chain will outperform and outlast standard 16B-4 chains, resulting in increased productivity and overall happy customers! Discover the newest innovations in roller chains when you choose DUROCHAIN 16B-4 roller chain; there's a reason why we put the "DURO" in chain!

Through-Hardened High-Strength Pins -

One of the most stressed components in a roller chain is the pins. The industry standard for premium chains is a case hardening process that provides a high-strength abrasion-resistant layer on the outer surface of the pin. This technique has been used for many years and does provide excellent strength and wear resistance until the hardness layer is worn. At DUROCHAIN, we use pins hardened to the core, called through hardened pins. This provides ample wear resistance throughout the life of the chain and increases strength.

• Precision Solid Round Parts -

Drastically improving chain wear life and performance of transmitting energy, solid bushings and rollers provide perfectly cylindrical bearing surfaces. Solid round parts require special manufacturing equipment that most factories will not make the initial investment in; however, the improvements in wear life and performance versus a chain with split round parts outweigh these costs in the long run. The issue with a split bushing or a split roller is when a chain experiences shock load or is used for some time, the split components will begin to deform, causing excessive internal wear and friction. All of our standard mild-steel DUROCHAINs use these solid round parts except hollow pin chains. Additionally, our bushings are made from alloy steel hardened to a specific HRC; the rollers are made from SAE steel and hardened to a specific HRC as well. We have found that these specific hardnesses provide the best wear life possible for the material itself.

• Max Countour Sideplates -

Precision made from steel alloy and hardened to an optimal HRC, our unique max contour side plates provide the highest shock load absorption and most extended wear life! The unique design adds additional material to the plate while maintaining the dimensional requirements of the American National Standards Institute (ANSI). DUROCHAIN max contour side plates add strength and wear life to their accompanied chain assembly compared to the standard side plates used by other tier-one chains.

• Quad-Staked Rivets -

DUROCHAINs are equipped with high-hold quad-staked rivets instead of the standard dual-stake rivets used by other manufacturers. This improves the chain's ability to withstand shock loads and side thrust. The superior rivet ensures that the chain is held together with the utmost capacity possible, giving it more versatile capabilities than its predecessors.

• Superior Plate Hole Preparation -

We compared processes to other premium roller chain plate holes to see the most effective and best method for achieving the maximum holding power possible. Most manufacturers use a simple piercing method when creating these plate holes; some use piercing and shaving processes. DUROCHAIN link plate holes are precision pierced, shaved, and ball drifted. Combining all three methods produces link plates capable of superior holding power and maximum pin-to-plate contact.

• Perfectly Factory Pre-Load -

DUROCHAIN is factory pre-loaded to a specific amount that ensures absolute minimal chain stretch. By today's standards, almost all roller chains are pre-loaded to some extent; however, a specific percentage achieves the best balance of reducing stretch and improving wear life. Extensive research was done to ensure DUROCHAIN was factory pre-loaded to this perfect percentage. Additionally, pre-loading ensures all components are perfectly aligned post-manufacturing for optimal performance.
