T-Series Machined Sprockets

T-SERIES

T-SERIES MACHINED SPROCKETS - for TRUE ½" x ½" BELTS

Used with True 1/2" x 1/2" Belts, Keystone's T-Series sprockets feature two full rows of precision machined teeth for uniform tooth engagement on every pitch of the belt. Compared with unmachined, skip tooth, or single row sprockets, Keystone's T-Series sprockets will provide longer belt and sprocket life.

¹ Add 0.375 inches to the Pitch Diameter to get the Overall sprocket Diameter. Subtract 0.375 inches from
the Pitch Diameter to get the Flange Diameter.
² Stock Bore Notations: NB = No Bore, CB = Core Bore, MPB = Minimum Plain Bore.
