1.2.3 RS-HT Roller Chain

Heavy transmission: Construction machines, agriculture machines, and tension applications

Application Example

RS-HT Roller Chains have higher tensile strength and less elastic elongation in comparison with RS Roller Chains. These characteristics are good for "lifting" applications (at low cycles), construction machines, and agriculture equipment (Figure 1.5).

Construction and Features

Compared with RS Roller Chains, RS-HT Roller Chains have the features shown below and in Table 1.4.

Appearance

  1. Link plate thickness is equal to the next-larger chain.
  2. Quad-staked riveting on the pin head helps hold the link plate on the pin.
  3. Rollers are seamless, not curled.
