Sprocket 16B-1 z=39 with hub

Product Description

Sprocket 16B-1 z=39, with hub

Sprocket 16B-1 (pitch 1" - 25.4 mm), simplex, 39 teeth, with hub. 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

Do I need to select dedicated bearings for a sprocket with hub?

A sprocket with hub mounted with a key does not require its own bearings - the load is carried by the bearings of the shaft on which the sprocket is mounted. A dedicated bearing built into the sprocket is only needed for tensioning or guide sprockets mounted on an axle without its own drive.

What happens when a sprocket operates under a greater load than intended?

Overloading first accelerates normal tooth wear, and with sudden overloads (e.g. machine blockage) the teeth may become permanently bent or sheared. In such cases, using an overload clutch in the system is often a better solution than choosing an oversized sprocket "just in case".

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).

Can I replace a simplex sprocket with a duplex one without changing the other drive components?

No - switching to a duplex chain and sprocket requires replacing the entire set (the sprockets on both sides of the drive and the chain) with a duplex version of the same pitch, because the rim spacing and chain width differ from those of the simplex version.

Where is this product used?

16B-1 sprockets are used in industrial drive transmissions: conveyors, feeders, packaging machines and production lines where precise, repeatable torque transmission matters.
