Sprocket 10B-3 z=26 with hub

Product Description

Sprocket 10B-3 z=26, with hub

The sprocket 10B-3 shown is a triplex (three-strand) sprocket with 26 teeth, made with a hub, for chain with a pitch of 5/8" / 15.88 mm. 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

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 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 can you recognise a sprocket not made in accordance with the DIN 8187 profile?

Most often it is visible from the incorrect seating of the chain on the teeth - the chain "sits" on the tooth tips or too deep in the tooth roots, despite the correct pitch. In that case, it is worth placing a section of a known reference chain of this pitch on the sprocket and checking whether it engages each tooth evenly and smoothly.

When is it worth using a clamping bush (Taper Bush) for a sprocket?

Wherever fast assembly matters. A clamping bush eliminates the need for laborious boring of the hub and cutting of a keyway - you insert the sprocket, tighten the screws and the machine is back in operation within minutes.

Where is this product used?

Typical applications of the 10B-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.
