Why choose Diamond Chain ? > The best roller chain for the job If youre looking for the best roller chain for the job, it will pay to take acloser look at Diamond roller chain. Diamond roller chain may look like your everyday chain, but upon closer inspection the unique differences that make Diamond chain better become evident. From the strict attention to detail we devote to every chain design, to the extra steps we take during fabrication and assembly operations, those differences really add up. We build long life, lasting value and enduring customer relationships into every link of chain...that...

You could look at two different brands of rollerchain and probably not see a difference on the surface. However, where you will see a difference is in the performance. The working load of a roller chain is often its most important characteristic. Contrary to popular belief, there is no consistent relationship between a roller chains working load capacity and its ultimate tensile strength. Many times chains are selected on their published tensile strengths, which are breaking loads. Chains must be selected based upon loads that they can transmit repeatedly over millions of cycles. So, chains with...

Specially developed processes include optimized heat treatment, the preloading of chains before packaging, high quality initial lubrication, and the precision tolerances to which the components are designed and manufactured.Diamond Chain regularly perform wear testing of chains taken fromproduction. Results are compared against a long...

The manufacturing process > The process of manufacturing the longest lasting chain begins bypurchasing the materials to detailed specifications. This is the way weve always done it because we must specify chemistry, dimensional size and even the direction of the grain in order to produce components capable of performing to your expectations. Transforming these raw materials into individual components that meetour high standards is no easy task. Again, weҒve learned that attention to detail is a key to achieving the desired result, which is the users satisfaction. Some of the steps taken to provide...

Along with the British Standard chains featured in this publication, DiamondChain Company offers a full line of U.S. manufactured ASME/ANSI roller chains. This product offering includes: > Though these are referred to as standard chainsӔ, they are anything but. Diamonds standard and heavy series roller chains, built to ASME/ANSI B29.1 standards, are manufactured to very specific requirements. The only thing standard about our chains are their ability to fit many standard applications. From industry to agriculture, our Standard and Heavy Series chains are designed to last longer than any other...

To obtain maximum service-life and efficiency from a chain drive, it isnecessary that certain precautions in installation be taken. Chain drive installation is relatively simple and good results may be obtained when the following conditions are met:1. The roller chain, sprockets, and other components are in good condition.2. The sprockets are properly aligned.3. Provision is made for adequate lubrication.4. The chain is correctly tensioned.Shafting, bearings, and foundations should be supported rigidly tomaintain the initial alignment. Roller chain should be free of grit and dirt. Wash chain...

Roller chain consists of a series of connecting traveling metallic bearings,which must be properly lubricated to obtain the maximum service life of the chain. Although many slow speed drives operate successfully with little or no lubrication beyond the initial factory lubrication, proper lubrication will greatly extend the useful life of every chain drive. The chain drive requires lubrication for six purposes:1. To resist wear of the pin-bushing joint. 2. To cushion impact loads. 3. To dissipate any heat generated. 4. To flush away foreign materials. 5. To lubricate chain-sprocket contact surfaces....

All chain drives should receive regular maintenance. Each driveshould be inspected after the initial 100 hours of operation. Thereafter, most drives may be inspected at 500 hour intervals. However, drives subjected to shock loads or severe operating conditions should be inspected at 200 hour intervals.At each inspection, the following items should be checked andcorrected, if necessary. > Check for roughness or binding when the chain engages or disengagesfrom the sprocket. Inspect the sprocket teeth for reduced tooth section and hooked tooth tips. If these conditions are present, the sprocket...

When adjustable centres or idlers cannot be used, the exact centredistance must be calculated and built into the drive. Drives with fixed centres should be conservatively selected and well lubricated to minimize the rate of chain wear. Adjustment for wear elongation in fixed centre distance drives is accomplished only by removing links or pitches to compensate for wear elongation. > The individual joints in a roller chain articulate as they enter and leave the sprockets. This articulation results in wear on the pins and bushings. As material is worn away from these surfaces the chain will gradually...

Lets face it, there are less expensive chains out there, but are theyworth it? Probably not in the long run. In most cases, cheap chain doesnҒt last as long so you have to replace it more often. That means downtime and all of the costs associated with it: idle workers, lost production, repair/replacement cost - it all adds up. Dont be fooled. Initial costs arenҒt necessarily real costs. Clarifying the real costs associated with less expensive chain can be done very easily. Using chains and costs that reflect your specific drive conditions, use the following worksheet to illustrate the investment...
