Material - The cast links are made of high grade Duramal
with holes smoothly cored for a close fit over the pins. By use of special pattern
equipment and tools, accuracy of pitch is assured and clearances between all wearing
surfaces reduced to a minimum. Duramal chain has heat-treated pins with Duramal
block links. Super Duramal chain has heat-treated pins and sidebars with Duramal
block links. Chains are also available with block links of File Hard
Duramal.
Assembly - Riveted construction is recommended for woodyards
and sawmills. Cottered construction is recommended for elevators and
conveyors. Riveted or cottered construction must be specified. Chain pins will
be staggered, except on C55, N77 & C188 chain.
Operation - Either the plain or "N" types of chain
will operate on the same type of sprocket. These two different types of chains
should not be coupled together. In many sliding applications chain working life may
be almost doubled by inverting the plain links to compensate for wear.
Interchangeability - This chain is interchangeable with other
standard makes of corresponding sizes and numbers.
Application - This chain is well suited for the handling of
stone, cement, gravel, and other abrasive materials. It is also used extensively in
general elevating and conveying service where a strong durable, yet inexpensive chain is
required.
