Product Description

Finished Bore Sprockets is a roller chain sprocket with precision machined holes, standard keyways, and two set screws. These sprockets are commonly referred to as "Type B" or "Type BS", with a keyway and two set screws at one end, one located above the keyway and the other at a 90 degree angle to the keyway.

They are made of high-quality carbon steel and the teeth have undergone hardening treatment. This type of sprocket is widely used in various industrial fields, such as conveyor systems and mechanical transmission systems, for transmitting mechanical power between rotating shafts.
