Sprocket 32B-1 z=29 with hub

Product Description

Sprocket 32B-1 z=29, with hub

Simplex sprocket 32B-1 with hub, 29 teeth - designed for chain with a pitch of 2" (50.8 mm). The material is C45E carbon steel (EN 10083-1), and the teeth remain unhardened (without induction hardening) - in accordance with DIN 8187 / ISO 606; this version is easier to machine over the entire depth of the sprocket.

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 can you check that the sprocket meshes correctly with the chain when the machine is started for the first time?

At low speed (e.g. turning the shaft by hand), it is worth observing whether the chain enters and leaves the teeth smoothly around the entire circumference of the sprocket, without catching or jumping. Any irregularities in operation at this stage usually indicate an alignment error rather than a defect in the sprocket itself.

How should a chain drive be lubricated to extend its service life?

The lubricant should get between the rollers and plates of the chain, not just onto its outer surface - it is best applied to the lower (slack) part of the chain, just before it runs onto the sprocket. In a dusty environment, a thick grease works better, while at high speeds a lower-viscosity oil that penetrates the joints more easily is preferable.

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. The hub is usually soft and easy to machine, even in the version with hardened teeth.

Where is this product used?

32B-1 sprockets are used in industrial drive transmissions: conveyors, feeders, packaging machines and production lines where precise, repeatable torque transmission matters.
