Description

About KANA NK100B Sprocket

KANA NK100B is the hub-type sprocket for No.100 (JIS/ANSI 100) roller chain: 31.75 mm pitch, 19.05 mm roller, 17.6 mm tooth width. CTS stocks 41 tooth counts from 9T to 70T, with outside diameters from 106 mm to 726 mm, stock bores of 20 mm up to 29T and 26 mm from 30T, and maximum bores from 40 mm at 9T to 103 mm at 70T. Sizes up to 21T are machined from solid C45 steel with induction-hardened teeth; 22T and above use a welded Fe360 body, which keeps large diameters manageable - the range runs from 1.6 kg at 9T to 64.7 kg at 70T. Every size is dimensionally interchangeable with KANA and other JIS-standard sprockets, so an existing drive can be re-sprocketed without changing the shaft or the chain.

Quality Assurance:

ISO9001: 2015 and GB/T24001-2016 / ISO14001: 2015.

KANA 100A vs NK100B vs NK100-2B

KANA 100A

Plate wheel without a hub. It is bolted to a flat face and is the lightest option for a given tooth count.

KANA NK100B

Single-sided hub with a stock bore (this page). It mounts directly on the shaft, needs no separate carrier, and suits most conveyor and machinery drives.

KANA NK100-2B

Duplex (two-strand) version for double-strand No.100 chain. Use it when the drive needs roughly twice the power capacity of a single strand.

If your drawing shows a bolt circle instead of a bore, take 100A. If the chain is two strands wide, take NK100-2B. Otherwise, NK100B is the default.
