Sprocket 10B-3 z=45 with hub, Cast iron

Product Description

Sprocket 10B-3 z=45, with cast iron hub

The sprocket 10B-3 shown is a triplex (three-strand) sprocket with 45 teeth, made with a hub, 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

Is it worth using guards on sprockets and the entire drive?

Yes - a guard protects operators from contact with moving parts and at the same time limits the ingress of dust and moisture to the chain, which genuinely extends its service life. In many industrial machines, a chain drive guard is also an occupational safety requirement.

Do you offer sprockets made to custom dimensions, outside the catalogue?

Yes, in addition to catalogue items we also manufacture sprockets to individual drawings or customer requirements - please contact the sales department and provide the required parameters (pitch, number of teeth, hub dimensions, material).

Does a larger number of teeth always mean a longer service life for the sprocket?

Largely yes - the more teeth are engaged, the lower the load on each individual tooth, and the chain runs over a larger wrap angle, which reduces dynamic impacts. Very small sprockets (with fewer than fifteen or so teeth) wear the fastest and are best avoided if the drive design allows.

In what cases are multi-strand sprockets used?

They are used to drive multi-strand chains in heavily loaded machines where there is no room for a wider sprocket with a larger pitch. Several strands distribute the load evenly, preventing premature chain breakage.

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?

10B-3 sprockets operate in drives of construction machinery, goods lifts, aggregate conveyors and woodworking machines - wherever tooth durability under load matters.
