Sprocket 10B-2 z=114 with hub, Cast iron

Product Description

Sprocket 10B-2 z=114, with cast iron hub

Duplex sprocket 10B-2 with hub, 114 teeth - designed for chain with a pitch of 5/8" (15.88 mm). Cast iron version of the sprocket - the tooth geometry is identical to the steel version with the same pitch and number of teeth; the bore in the hub is a pilot (preliminary) bore, and the exact size is achieved by turning.

Technical data

Frequently asked questions

How often should chain tension be checked on a machine in operation?

In machines operating continuously, it is advisable to check the tension every few weeks, and in a newly installed drive - as early as after the first hours of operation, when the chain "beds in". A correctly tensioned chain has a slight, visible sag on the slack side - too tight a chain accelerates bearing wear, while too loose a chain increases the risk of it jumping off the sprocket.

How can a sprocket and chain be protected against corrosion during storage?

After cleaning off any dirt, it is advisable to apply a layer of preservative grease or anti-corrosion oil and store the sprocket in a dry place not exposed to condensation. In the steel version (without coating), even a short damp break in the workshop can cause a rusty film on the tooth surfaces.

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).

How can you check whether the chain in an existing drive is already excessively elongated (stretched)?

Stretch out a section of a dozen or so chain links and compare its length with the catalogue dimension - an elongation of more than approx. 2-3% means the chain is due for replacement. A stretched chain no longer seats properly on the sprocket teeth, which accelerates the wear of both components, so it is better to replace it before it damages the sprocket as well.

Is a duplex sprocket the same as a tandem sprocket (for two single chains)?

No, even though they look very similar. A tandem sprocket is also a single, monolithic sprocket, but with a different (wider) spacing of the toothed rims - designed specifically for two independent simplex chains running in parallel. This duplex sprocket has a rim spacing matched to a single duplex chain, in which both strands are integrated with each other. Using a duplex sprocket for two single chains is a mistake - the spacing is too narrow and the chains will rub against each other, which leads to accelerated wear and, in extreme cases, to serious drive failure.

Does a cast iron sprocket require a different chain than a steel sprocket of the same pitch?

No - the tooth geometry and pitch are identical to those of the steel version of the same size, so the cast iron sprocket works with the same chain. The difference lies in the material of the hub and rim: cast iron dampens vibrations better and is cheaper, but withstands impacts and operation at high rotational speeds less well than steel.

Where is this product used?

Typical applications of the 10B-2 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.
