Master Chain

Flat Link Mining Chain according to DIN 22255

It is a chain type in which one of the two links has a flat surface and thus the external width of the vertical link is reduced. Since the height of the flat links produced according to DIN 22255 is less than the height of the round links produced according to DIN 22252, it will be possible to use higher diameter chains in the same conveyor line with small changes. For example, instead of DIN 22252 26x92mm round link chain with outer width of 85mm, a flat link chain of 30x108mm according to DIN 22255 corresponding to an outer width of 85mm may be used. Masterchain manufactures flat link chains for mining industry in Grade80 and Grade 100 quality in the range of 26-48mm diameter according to DIN 22255. Special chains can be produced according to different customer project demands.
