Description

About KANA NK25B Sprocket

KANA NK25B is the hub-type sprocket for No.25 roller chain - a 6.35 mm (1/4 in) pitch chain with 3.30 mm rollers and a 3.18 mm inner width, matched to a 2.8 mm tooth width. CTS stocks 44 tooth counts, from 10T with a 23 mm outside diameter and a 20.55 mm pitch diameter to 80T with a 165 mm outside diameter.

The B in NK25B means hub type: a raised hub carries the bore and keyway while the plate stays thin. If your layout needs a flat plate, the plate-type version is listed as KANA 25A.
