Rexnord- the quality standard for marine diesel roller chains!

• Rexnord chain pins and bushings are especially wear-resistant due to outstanding case depth hardness.
• Chain rollers have high strength because they are through-hardened and manufactured from high-precision seamless tubes.
• Rexnord offers complete quality assurance in each and every production step.
• Rexnord marine diesel roller chains possess outstanding fatigue strength and thereby optimum operational safety.

Marine diesel roller chains can also be considered for use on critical drives in industrial applications. They are particularly advantageous for drives operating at the acceptable limits of standard roller chains, for drives requiring high efficiency and reliability, and especially useful for replacing chain drives susceptible to fatigue fractures.

Rexnord Research Findings

In the case of marine diesel roller chains, operational safety is the most important factor overall. As a result of extensive research and development, Rexnord has developed a new plate design which increases the fatigue resistance by more than 30%. Full stress analysis has been carried out to balance the link plate height limitation with the cross-section and the increase in length in the link plate head.

Matching of Timing Roller Chains

If two or more chains for the same drive are being used, then an exact matching of chains is of utmost importance. The Rexnord method of matching of individual chain length and selective composition of these lengths ensures extremely high precision over the complete chain length. Rexnord chain-matching meets all requirements of all engine manufacturers.
