Simplex roller chain is mean of single strand industrial roller chains which are functioned in the range of ¾? to 2? in BSS and ANSI. Duplex Roller chain is a mean of double strand industrial roller chain which is functioned in the range of ¾? to 2? in BSS and ANSI. Triplex roller chain is a mean of double strand industrial roller chain which is functioned in the range of ¾? to 2? in BSS and ANSI. Chains without roller are frequently used for handling static or intermittent loading in forklifts and other applications where rollers are not required. Leaf Chains - Used where greater tensile strength than roller chains and run over the sheaves rather than sprockets, mostly used as accouter, Weight for machine tools, elevator and open door, forklift truck masts, spinning frames, and similar lifting or balancing applications.

[...] 10) If the hardness is not correct and is above limits, then load the lot, in the second Heat Treatment Chamber for the Tempering process or hardness lowering process. 11) Set the time and Heat parameters as per the instructions of Management Representative. 12) After the time of the process is finished, unload the lot and check for the hardness on a sample lot of 5 pieces. 13) If it is either correct or lower than required then send the lot for the next process. 14) If it is not then reload it. 15) Send the pieces to the next stage i.e. Barreling. [...]

Barreling: Barreling is a process where the lot that is removed out of the Heat Treatment Chamber is cleaned so that the shining of the pieces surfaces out. [...]


[...] Load the two ends of the chain in the two ends of the preloading machine. Load the machine as per the chart present, and as per the required series. Refer to the instructions of Management Representative for the same. Check whether the chain withstands the load. If yes then remove the chain and proceed to test all the other chains. If no then check the same again. Measure the length: The following are the steps in the Length measuring. Load the chain that is to be tested for length measuring at the two [...]
