Sprocket 08B-1 z=52 with hub, hardened

Product Description

Sprocket 08B-1 z=52, hardened hub

Sprocket 08B-1 with hardened hub, 52 teeth, simplex - a product matched to chain with a pitch of 12.7 mm (1/2"). The material is carbon steel C45E (EN 10083-1), and the teeth undergo induction hardening to 45-55 HRC - in accordance with DIN 8187 / ISO 606; the hub retains a lower core hardness, so it can be machined safely.

Technical data

Frequently asked questions

Can a sprocket be welded directly to the drive shaft?

Technically this is possible, but we strongly advise against such a solution. Welding overheats the material, damages nearby bearings, bends the shaft and prevents the worn sprocket from being easily replaced later. Always use mounting with a key or a clamping bush.

How do I bore the hole in a sprocket to fit a motor shaft?

A sprocket with a pilot bore should be clamped in a lathe (gripping the hub to avoid runout) and bored to the required diameter with an H7 tolerance. If the sprocket has hardened teeth, the hub is usually soft and easy to machine.

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).

What causes premature wear of the side faces of the teeth?

This is most often the result of misalignment of the sprockets on the shafts (so-called lateral runout of the drive). The chain does not run straight, and its inner plates catch on the sides of the teeth, wearing them down to bare metal. The system must be realigned immediately.

Where is this product used?

08B-1 sprockets are used in industrial drive transmissions: conveyors, feeders, packaging machines and production lines where precise, repeatable torque transmission matters.
