These type of Chain are used in Cement Industries for handling hot clinker. These Chain are fitted with "Out-Board" Rollers.

These Chain are of longer pitch with double strand & are meant for heavy duty services of high yield strength & to withstand the heavy shock loads. Links are with locking arrangement to avoid overlapping due to long pitch. Maximum Chain strength & wear resistance is achieved by selecting proper material & adequate heat treatment processes.

Chain links are made from Medium Carbon / Alloy Steel. These links are subjected to operations like Blanking & fine boring, which are carried out on highly precision machines. The link hole size & finishing is controlled to suit adequate interference fit. Further links are hardened & tempered to avoid linear elongation & to get better impact strength followed by Shot peening process to improve the fatigue strength.

Special Alloy Steel is used for Pins & Bushes with Case Carburized hardening & Tempering process to get the maximum wear resistance & core strength.
