At Toronto Gear Works, we deliver products that put emphasis on precision engineering and pristine manufacturing quality. Our minimum plain bore (MPB) roller chain sprockets are perfect for applications where a bushing’s maximum load is hindered due to space constrictions.
We offer A style (hubless) sprockets in pitches of #25 (0.250”), #35 (0.375”), and #40 (0.500”). These plate sprockets are offered from stock in steel.
Toronto Gear Works also offers B style (hub) sprockets in pitches of #25 (0.250”), #35 (0.375”), #40 (0.500”), #41 (0.500”), #50 (0.625”), and #60 (0.750”). These minimum plain bore sprockets are offered from stock in steel. We also offer stainless steel sprockets with minimum plain bores and hubs for #25 roller chain.
Roller chain sprocket part numbers can be determined as follows:
Chain + (A for Hubless or B for Hub) + Number of Teeth
For example, 35A112 is a roller chain sprocket made for use on a #35 chain. It is a type A sprocket meaning that it does not have a hub. It has 112 teeth.
In addition to this part number format, stainless steel sprockets are specified by adding a “SS “ to the end of the part number, such as in a 25B25SS roller chain sprocket.
