1/2" X 1/8" (081) Steel Simplex Sprockets
These sprockets are supplied with a pilot bore that can be machined to a larger accurate diameter (subject to boss size) although many users find the pilot bore quite acceptable. Using our 'Custom Machining' service, we can also drill and tap for set (grub) screw fixing. See the 'Custom Machining' tab with each product for more information.
Nominal tooth width: 1/8"
Boss width: 14 to 25mm depending on sprocket size
