NOTHING OUTLASTS A DIAMOND
At the Diamond Chain Company, we manufacture the world's highest-performing roller chain. From the Wright Brothers, to Henry Ford, to global leaders of our time, Diamond Chain is the roller chain most trusted to perform, when performance matters most.
Case Study: Vacuum Planter
 

A custom manufacturer of vacuum planting equipment was concerned that rust was developing on their planter's roller chain prior to factory shipment.

 

Sometimes referred to as red oxidation, rust is corrosion that results from metal reacting with oxygen. Far from just a cosmetic issue, rust reduces the mechanical strength of metals which contributes to an

 unpredictable reduction in service life. 

 

Because of high humidity levels or locations near large bodies of water, certain areas of the country are more likely to encounter issues with rust. In addition, because of abrasive regional soil types, some customers request that no additional lubrication be added to the chain to prevent damage to the chain's pin but this is actually compounds the problem as the chain's lubrication typically includes a rust inhibitor.

 

It was determined that a corrosion resistant product would be necessary to combat rusting during manufacturing with the added benefit of extended service life while out in the field. The manufacturer had two types of product solutions to consider-- stainless steel or plated roller chain. 

 

While stainless steel has higher corrosion resistance than plated chain, the reduction in power transmission and the higher cost of the materials eliminated this as a potential option. It was determined that a plated product would be a more cost effective solution and a nickel plated corrosion resistant chain was selected as the solution. 

 

Following the switch to a nickel plated roller chain, this manufacturer has eliminated rusting chain on their production line and they are looking to incorporate the nickel plated chain onto additional application.

 

The benefits of this chain have also extended the end users of the planting machinery. With addition of the corrosion resistant finish, the chain is now lasting up to four times longer in service. 

 

Q- What is the difference between slip-fit and press-fit link plates in multiple strand roller chain? 

 

A- Roller chains manufactured using slip-fit link plates are the most common and are suited for drives of moderate severity. These chains are designed for ease of disassembly throughout the entire length of chain. With that being said, the chains can be shortened or sections can be added quickly with minimal effort. Slip-fit link plate design may cause the user to experience accelerated fatigue failures in exchange for the ease of alteration in the field.

 

Roller chains manufactured using press-fit link plates were originally developed by Diamond Chain Company for service in applications that require the utmost in multiple strand chain capacity. Press-fit link plates have greater fatigue strength than slip-fit link plates, because press-fit construction assures rigid permanent support for the pins at each tension point with no relative movement.  The pin in slip-fit multiple strand chain is able to deflect, under load, due to the clearance, the press-fit center plates provide rigid support to the pin.

 

While press-fit construction does provide the increased fatigue resistance that is often essential in critical applications, the user does give up some convenience because the chain's length can not readily be altered in the field. For this reason press-fit riveted multiple strand roller chain should always be ordered in the exact pitch length required, including a Bushed Center Plate Link (BCL) connecting link.

DID YOU KNOW?
 

The left-hand digit in the two-digit part number denotes the number of 1/8" segments in the pitch. For example, ANSI 80 chain would be 8 segments of 1/8" for a total of 1".

 

IN THE NEWS
 
Diamond Chain is excited to announce the launch of our new Universal Chain Breaker!

Unlike traditional chain breakers, which can only manage one chain size at a time, the Diamond chain breaker can accommodate six sizes of chain via a rotating jig, eliminating the need to constantly change extractor pin inserts.
 
And, the Diamond chain breaker accommodates both ASME/ANSI and ISO/British Standard chains.
 
The chain breaker will be available to ship in September. For more information, send us an  email atmarketing@diamondchain.com

 


 
 
The lowest chain solution will generally consist of a single strand of chain using the smallest pitch size that can accommodate the necessary working load.
