Crown Industrial Corporation

While silent chain is commonly used as high speed drive, it is also an excellent conveyor chain in many applications. The open area of the chain allows air flow through the conveying surface, the steel construction is extremely strong, durable, and able to withstand much higher ambient temperatures than many other common conveyor belt materials. And the smooth sprocket engagement results in constant and stable surface velocity allowing you to move materials at faster speeds without the conveyed material tipping or falling.

Conveying applications are one of the most common uses for attachment chains. Crown Industrial can provide you with all the right features for your conveyors. In addition to single and double pitch roller chain, we can add any type of attachments you need. We offer large rollers in both heat treated carbon steel and wear resistant composite material. And, on request, we will match your conveyor chain strands for precision length control, which is the key to even chain loading and trouble free operation when a system uses two or more parallel strands. There is no additional charge for basic matching services, and it adds no additional time to the delivery schedule. Just specify that you require matched strands on your next conveyor chain order.

Our Excel series of high performance inverted tooth chain offers significant performance improvements over standard silent chain. A wider waist and modified tooth profile on the link plates and improvements to the pin geometry allow for higher loads, faster speeds, and smoother operation. The modified tooth profile of the chain is matched by the sprocket tooth profile, so Excel series products are not compatible with ASME standard silent chain sprockets. Excel chain can be interchanged with chains produced by some other manufacturers, such as an RPV or HV chain type. Click here for more info.

Are you currently using Ramsey RPV™ chain? Our Excel series is a top quality, performance chain which can be interchanged with some of the other products on the market, saving you money without compromising performance. In many cases, you can switch chains and still use your existing sprockets. Contact us today and we will examine your specific application and recommend the right product for your situation. We can also help you interchange other custom silent chain products like duplex chain, coupling chain, or conveyor chain, and most of the time, a sprocket change is not required.

We support most standard attachment chains with our quick assembly process. Components are in stock for 12" to 3” single and double pitch chain styles. You give us the size and spacing of the attachments and we will assemble and ship your order, generally in 5 working days or less. For breakdowns and other time critical situations, we offer expedited assembly and shipping to get your chain to you even faster. We offer attachment chains with extended pins, bent tabs, and straight tabs. Standard attachment tabs have 1 hole, and double pitch and wide tab single pitch links are also available with two holes. Our Attachment Chain Worksheet is a PDF file that lists many of the standard attachments we offer, and it contains an easy-to-use worksheet to specify your chain quote request. If standard attachment chain is not what you need, we can do basic modifications or manufacture a totally unique chain to your exact specifications.

All of our chains are designed and manufactured to deliver the best possible performance and long life. Precision components result in better performing chain: Link Plates – apertures are stamped in a two-step process to produce a straighter side-wall which is the key to long lasting chain Precision pitch control, or aperture center distance, results in smooth, quiet, reliable operation Link plates are heat treated for maximum wear life and toughness Shot peening provides compressive forces on the apertures to maximize fatigue strength of the chain Pins – The two pin design uses precision drawn material to produce consistent parts with the proper form to allow smooth articulation as the chain travels around the sprocket. The case hardening heat treatment process give the pins maximum surface hardness to maximize chain service life while keeping the core of the pins strong and ductile to maximize chain tensile strength. After lacing and riveting the chain, our pre-loading process is the final step in precision control of the chain pitch. Pre-loading significantly reduces chain stretch during the initial wear-in when the chain is installed in your application. This results in consistent chain that lasts longer and runs smoother. Finally, the chain is lubricated and packaged with your choice of connecting methods. Strands can be supplied endless for applications that allow for installation that way. Otherwise, we offer a variety of rivet type of drilled pin type master links. Click here for more information on master link options.
