08B (1/2") plate sprockets

08B plate sprockets are flat plate wheels for 08B roller chain of 1/2" (12.7 mm) pitch to DIN 8187 / ISO 606 - one of the most widely used chains in agricultural machinery, conveyors and general drives.

08B (1/2 inch) plate wheels - a sprocket on your own hub, drum or flange

A plate wheel without a hub lets you build a sprocket exactly for your machine: on your own hub, drum or flange. A bolted-on rim can later be replaced without removing the hub from the shaft. In the simplex version you can choose from a wide range of plate wheels with induction-hardened teeth, which cope better with dust, sand and frequent starts.

08B simplex, duplex and triplex plate sprockets, also with hardened teeth

Simplex, duplex and triplex plate wheels in C45 steel, in separate subgroups. Versions with hardened teeth are available mainly among simplex plate wheels, and individually also among triplex ones.

08B plate wheel vs ASA 40 chain - frequently asked questions

Does an 08B plate wheel fit ASA 40 (08A) chain?

No. Both chains have a 12.7 mm pitch, but differ in roller diameter and inner width. For American chain choose a sprocket from the ASA sprockets group.

Do the teeth lose hardness when a hardened plate wheel is welded?

No, provided the weld is near the bore, away from the tooth rim, and the plate is not overheated. Only the teeth are hardened, while the centre of the plate remains soft and welds well.
