Sprocket 10B-3 z=57 with hub

Product Description

Sprocket 10B-3 z=57, with hub

The sprocket 10B-3 shown is a triplex (three-strand) sprocket with 57 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 should a chain drive be lubricated to extend its service life?

The lubricant should get between the rollers and plates of the chain, not just onto its outer surface - it is best applied to the lower (slack) part of the chain, just before it runs onto the sprocket. In a dusty environment, a thick grease works better, while at high speeds a lower-viscosity oil that penetrates the joints more easily is preferable.

How can you recognise an idler sprocket bearing that is starting to wear before it fails?

The first symptom is usually increased noise and noticeable, excessive play of the sprocket when it is moved by hand with the machine stopped. It is also worth periodically checking the temperature of the bearing housing during operation - an increase compared with other bearings in the system signals progressive wear.

Is it possible to order a single trial piece of the sprocket before placing a larger order?

Yes, catalogue items can be ordered in any quantity, including a single piece for testing or verification before a larger series order.

How does rotational speed affect the selection of the minimum number of teeth of a sprocket in the system?

At higher rotational speeds, a larger minimum number of teeth on the smallest sprocket in the system is recommended to reduce chain vibration and impacts resulting from the so-called polygon effect. With very small sprockets (e.g. 9-11 teeth) and high speeds, wear and vibration levels increase significantly faster than with larger sprockets.

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.
