Sprocket 08B-1 z=14 with hub, hardened

Product Description

Sprocket 08B-1 z=14, hardened hub

Simplex sprocket 08B-1 with hardened hub, 14 teeth - designed for chain with a pitch of 1/2" (12.7 mm). Sprocket compliant with DIN 8187 / ISO 606, milled from C45E steel (EN 10083-1); the teeth are induction hardened (45-55 HRC), while the core and hub remain soft, allowing the bore to be safely machined to the shaft size.

Technical data

Frequently asked questions

How do I select a sprocket with bearing for a tensioning system?

An idler sprocket (with built-in bearing) is selected according to the pitch of the working chain and mounted on the slack side (not on the tight side). It is important that the bearing is protected against dust, especially in agricultural machinery.

How do you correctly align sprockets during installation?

The driving and driven sprockets must be in one perfect line. You can use a long steel straightedge placed against the faces of both sprockets or a professional laser alignment tool. Even a slight angular deviation will quickly destroy the chain.

What forces act on the key in a sprocket and how can it be prevented from shearing?

The key transmits the entire shearing torque between the shaft and the sprocket. Make sure it is made of suitable quenched and tempered steel, has an accurate fit in the keyway and that the machine is not subjected to extreme jerks without an overload clutch.

How does induction hardening of the teeth affect abrasion resistance?

Induction hardening hardens only the surface layer of the tooth, where the chain rollers bear. The tooth is resistant to wear, while the sprocket core and hub remain elastic enough to safely absorb impacts and be suitable for boring.

Where is this product used?

This type of sprocket is used in drives of agricultural and industrial machinery, including screw and bucket conveyors, feed conveyors, packaging machines and internal transport systems.
