Sprocket 10B-1 z=12 with hub

Product Description

Sprocket 10B-1 z=12, with hub

Simplex sprocket 10B-1 with hub, 12 teeth - designed for chain with a pitch of 5/8" (15.88 mm). The sprocket complies with DIN 8187 / ISO 606 and is made of C45E steel (EN 10083-1); the teeth are not hardened, which lowers the cost of the sprocket and makes it easier to machine (e.g. deep boring of the hub) throughout the entire volume of the material.

Technical data

Frequently asked questions

Can the hub of a sprocket have a different hardness from the toothed rim?

Yes, and in practice this is usually the case - in the version with induction-hardened teeth, only the toothed rim is hardened, while the hub remains soft so that it can be freely turned and a keyway can be cut in it. This solution combines tooth wear resistance with ease of machining the hub.

Does the difference in hardness between sprocket and chain affect their rate of wear?

Yes - chain and sprocket manufacturers select hardness so that they wear as evenly as possible, rather than one element "cutting down" the other. An excessively hard sprocket working with a soft, non-certified chain (or vice versa) leads to faster wear of the weaker element.

Is a sprocket with hub suitable for reversing drives (with a change of rotation direction)?

Yes, the tooth geometry of a sprocket is symmetrical and has no preferred direction of operation, so the sprocket can be used in drives that change direction of rotation. In such systems, correct chain tension on both sides is particularly important, because when reversing, each side alternately becomes the working side.

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.

Where is this product used?

Applications include drives in the food industry, packaging machines, sorting lines and agricultural harvesting machines, where the sprocket operates seasonally but under full load.
