Product Description
Sprocket 10B-1 z=9, hardened hub
The sprocket 10B-1 shown is a simplex sprocket with 9 teeth, made with a hardened hub, for chain with a pitch of 5/8" / 15.875 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.

Frequently asked questions
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.
How do you calculate the pitch circle diameter of a sprocket?
The pitch circle diameter (Dp) is, in simplified terms, the line along which the chain rollers roll. It is calculated using the formula: pitch divided by sine (180° / number of teeth).
When does tooth wear (the "shark fin" profile) mean the sprocket must be replaced?
If the teeth resemble pointed, tilted shark fins, the sprocket must be replaced immediately. Operating on such a profile can damage even a brand-new chain within a dozen or so days.
What is the relationship between the number of teeth of a sprocket and the rotational speed of the drive?
This is the basic principle of the transmission ratio. If there is a small sprocket on the motor (drive) and a large one on the machine, the machine will turn more slowly but gain proportionally greater torque (force).
Where is this product used?
10B-1 sprockets are used in industrial drive transmissions: conveyors, feeders, packaging machines and production lines where precise, repeatable torque transmission matters.
