Minimum Plain Bore Sprockets
B&B Manufacturing is a trusted source for quality-engineered and precision-manufactured minimum plain bore (MPB) roller chain sprockets in applications where space constraints prohibit use of a bushing to handle maximum load.
Made from steel and stainless steel, we feature MPB sprockets that include both A plate and B (hub) styles. See our full line of MPB roller chain sprockets in our catalog.
