16B (1") hardened hub sprockets

16B hardened hub sprockets work with 16B roller chain of 1" (25.4 mm) pitch to DIN 8187 / ISO 606. 16B chain carries high loads in heavy conveyors and agricultural machinery, and hardened teeth let the sprocket withstand them longer.

16B hardened sprockets - slower wear under high loads and dust

High loads accelerate tooth wear, especially in dusty environments. Teeth hardened to 45-55 HRC slow this process down considerably, and the tough C45 steel core copes well with shocks. The hub remains soft - you make the bore and keyway for your shaft.

1 inch hardened sprockets in simplex and duplex versions

16B-1 simplex and 16B-2 duplex sprockets with hardened teeth - each version has its own subgroup. 16B sprockets with unhardened teeth and triplex versions can be found in the Hub sprockets group.

Hardened sprockets for 16B chain - customer questions

Does a 16B sprocket fit ASA 80 chain?

No. ASA 80 (16A) chain is narrower inside and requires a sprocket with a different tooth profile. A series sprockets can be found in the ASA sprockets group.

How should a drive with a hardened sprocket be maintained?

The same as any chain drive: lubricate the chain regularly, check its tension and elongation, and the alignment of the sprockets.
