Because Ramsey specializes in Silent Chain (Inverted Tooth) drives, we can provide solutions that are simply not available from other companies. Not only do we offer the widest range of standard chains and sprockets, we also custom design and produce...

2 Silent Chain Basics All silent chains are made up of stacked rows of flat, tooth shaped driving links that mesh with sprockets having compatible tooth profiles, much the way a rack and pinion mesh. Typically, chains will also contain guide links, whose purpose is to maintain proper tracking of the chain on sprockets. Washers or spacers may be present in some chain constructions. All of these components are held together by riveted pins located in each chain joint. Although all silent chains have these basic features there are still many many different styles, designs, and configurations. Chains...

Chains for power transmission Silent chain drives are capable of transmitting power with low noise, high efficiency, and reduced vibration, at speeds and loads that exceed the capability of other belts and chains. There are many styles of silent chain, and Ramsey offers a wide range of designs for different application requirements and budgets. Almost all Ramsey silent power transmission chains utilize efficient, quiet, two-pin roller bearing joints; technology which has been shown to outperform conventional, round pin joints. These chains can be found in a wide variety of demanding industrial...

Wear protected chain Ramsey wear protected chains use specially-designed links that cover and protect the sides of the chain to extend chain life and improve product handling. Chains are designed to run in direct contact with lateral guides or transfer plates, and assist with smooth product transfer. No other design offers the protection of Ramsey’s wear resistant chains. 8 AllGuard FX chain • Chains are protected to prevent premature chain failure and pin head wear. • Pin heads are protected from wear by being recessed in the side links. Made entirely of corrosion resistant 304 stainless steel...

Sprockets, gears and couplings Ramsey offers a full range of stock and made to order sprockets in pitches ranging from 3/16” pitch to 2 1/4” pitch. Stock sprockets are available with minimum plain bores or bored for taper lock bushings. For an additional charge they can be machined with a finished bore and keyway. Made to order sprockets provide an almost unlimited range of options and are a large part of our daily production. Ramsey also supplies sprockets to replace most competitors’ products. 9
