Sprocket 16B-3 z=57 with hub

Product Description

Sprocket 16B-3 z=57, with hub

Sprocket 16B-3 with hub, 57 teeth, triplex (three-strand) - a product matched to chain with a pitch of 25.4 mm (1"). Compliance with DIN 8187 / ISO 606 guarantees full interchangeability with a chain of the same pitch; the sprocket is made of C45E steel (EN 10083-1) in a non-hardened version - the standard choice for applications with moderate and medium load.

Technical data

Frequently asked questions

What should be considered when selecting a sprocket for low-temperature operation?

At low temperatures, carbon steel becomes more susceptible to brittle fracture under impact, so in cold stores and freezers it is worth considering a variant with increased impact strength or consulting the supplier on the choice of material. Equally important is the choice of a lubricant that will not thicken or lose its lubricating properties at low temperature.

How do sprockets for roller chains differ from sprockets for toothed chains (silent chain)?

A sprocket for roller chain has a rounded tooth root matched to the chain roller (profile according to DIN 8187), whereas a sprocket for toothed chain (silent chain) has a flat, trapezoidal tooth profile that engages the chain plates instead of rollers. These two systems are not interchangeable.

How do I check the radial and axial runout of a sprocket after mounting it on the shaft?

A dial indicator on a magnetic stand is used for the measurement. Place the tip against the circumference of the sprocket or its side face, rotate the shaft and check the deviations. Excessive runout indicates faulty installation or a damaged shaft.

Does a sprocket with hub have a fixed mounting side, or can it be reversed?

The sprocket is usually symmetrical with respect to the plane of the rim, so the rim itself cannot be "reversed incorrectly" - but the hub is usually on only one side of the sprocket, which determines which way the sprocket must be mounted relative to other components on the shaft (e.g. bearings, other sprockets).

Where is this product used?

Typical applications of the 16B-3 sprocket: drives for pumps, mixers and industrial fans, as well as control systems for industrial gates and roller shutters, where resistance to continuous operation is required.
