05B Chain Sprockets

Size 05B chain is the third smallest British Standard roller chain made. Because of this, high-precision tolerances are necessary not only for manufacturing the chain but manufacturing the sprockets as well. Our sprockets are made with these high-precision tolerances using state of the art modern equipment, they are also constructed out of a high-quality high-strength steel so not only are the 05B sprockets effectively high-performance, they also out-last other brands. Standard configurations for these sprockets include A-Plate and B-Hub (hub on one side), while stock bores will range from 5mm up to 20mm and outside diameters range from 24mm to 322.5mm.
