Silent chains provide a heat resistant, flat, durable, non-slip, conveying surface that can be customized to fit a wide range of industrial applications, designed to smoothly and efficiently engage sprockets, providing minimal speed variation in the conveying surface. Chain options include single pin or two pin joint construction, link-spacer or all link constructions and, pin head protection they are also 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

RPV™ Silent Chain
RPV is high performance inverted tooth chain, specifically designed to meet or exceed the capability of all other high performance chains. Capable of speeds in excess of 7000 fpm and loads exceeding 3000 hp, RPV's strength and load capacity comes from improved link and sprocket designs. Links are designed to minimize stress concentrations and to increase the amount of steel in the line of chain pull. Innovative stamping methods maximize the amount of load bearing surface in each link and greatly reduce the rate of chain elongation during operation. All links are shot peened to improve fatigue strength and produce a uniform, high quality finish.
RPV sprockets and links employ an involute tooth profile to decrease impact loading and vibration during chain engagement. RPV chain engages sprockets nearly tangent to the sprocket pitch circle, reducing the velocity variation produced by chordal action. Reduced velocity variation creates less vibration and translates directly to less wasted energy and higher load carrying capacity.
RPV is available in Type 115 or Type 139 link styles and will interchange with Morse HV chains and original Morse HY-VO chains. Ramsey RPV sprockets will also interchange with Morse HV sprockets and original Morse HY-VO sprockets.
Rampower Silent Chain
RP or RamPower series silent chain was designed to operate on sprockets manufactured with an ASME Standard tooth profile. Available exclusively through Luan Dung, RamPower offers twice the power capacity of SC series chains and speeds up to 7,000 fpm. RamPower has been successfully employed in applications transmitting up to 2,500 hp and is often preferred where high loads and speeds must be accommodated in a small amount of space.
The increased load carrying capacity of RamPower is a result of improved link and pin designs. Ramsey engineers re-designed the standard SC link shape to reduce stress concentrations, improve fatigue life, and increase link tensile strength. Innovative stamping methods were also employed to maximize the amount of bearing surface area in each link. The increased bearing area produces less stress in the chain joint and greatly reduces the rate of chain elongation during operation. All chain links are shot peened to improve fatigue resistance and produce a uniform finish.
In most applications RamPower will experience very little initial elongation, making it well suited for fixed center drive applications. We recommend RamPower for all new chain drives where the customer desires to use sprockets with the ASME standard tooth profile. It is also well suited for upgrading existing SC chain applications when improved performance is desired.
RamPower is available in center guide as well as side guide assemblies.
Available pitches: 3/8", 1/2", 5/8", 3/4", 1", 1 1/2", 2"
Rampower Duplex
Rampower duplex, also known as RP duplex, provides approximately two times the power capacity of standard SC duplex chain. RP duplex is often well suited for new or replacement applications where power or speed requirements exceed the capability of SC duplex chain.
SC Duplex
SC duplex chains have been around the longest, are used primarily in replacement applications, and are often the most economical. SC duplex offers the advantage of reduced weight, but with a lower power capacity.
Ramflex
Ramflex is LDC’s most robust duplex chain design; it is particularly well suited to applications where shock or very high loads are encountered, or where space is limited.
SC Silent Chain
SC chain can accommodate speeds approaching 6500 fpm and loads in excess of 1000 hp. Utilizing the patented LUAN DUNG roller bearing joint, SC chain is one of LDC’s most popular industrial chains.
SC series chains are available in center guide and side guide assemblies. Center guide assemblies are fully compliant with the ASME Standard for silent chain. Both side guide and center guide operate on industry standard sprockets
We recommend SC chain primarily as a replacement chain for existing power transmission applications where it has been successfully employed in the past. SC chain weighs less than an equal width of RPV or RP chain, and it typically costs less. Available pitches: 3/16", 3/8", 1/2", 5/8", 3/4", 1", 1 1/2".
3/16” Pitch SC Silent Chain
Constructed from hardened carbon steel or corrosion resistant, 304 stainless steel, Ramsey 3/16
Typical applications include: Food processing equipment, packaging machinery, weighing machinery, checkweigher replacement parts, postage meters, sorting machinery, as well as Mettler-Toledo Hi-Speed TM replacement chains and sprockets.
Note: The power capacity of stainless steel chains is less than comparable width carbon steel chains.
Silent Chains
Luan Dung application engineers can work with you to design and build a silent chain especially for your application. Special attachment links and unique chain designs are frequent requests with custom chains. Also, because we design and build our own tooling and use stocked materials whenever possible, both lead times and costs are minimized. There is no minimum order quantity. Contact Luan Dung sales for more information about custom chain options.
