B503 blockchain is manufactured with alternate block links (inside link) and pin links (outside link). Though it has a simple design it is a highly effective chain and is used in applications all around the world. Specifically, the B-503 block chain is the solid construction style, has a 1" pitch, and has a block width of 0.25". It is intended for use in light-load, low speed conveying systems and has a length tolerance of 0" - 1/16" per foot. To increase the lifespan of B503 chain a chain guide is recommended to be used (which we also supply), this reduces friction and reduces the catenary load on sprockets.
