Frequently Asked Questions (FAQ)

What are the advantages of V-belt pulleys with a cylindrical bore?

V-belt pulleys with a cylindrical bore offer a high degree of flexibility for further machining and adaptation to different shaft dimensions. The cylindrical pilot bore allows the bore, keyway, or other machining operations to be individually tailored to the requirements of the respective drive unit. This makes these V-belt pulleys particularly suitable for mechanical and plant engineering as well as custom-designed applications.

Can V-belt pulleys with a cylindrical bore be individually machined?

Yes. V-belt pulleys with a cylindrical bore are ideally suited for customer-specific finishing. Depending on the application, the bores can be reamed or bored to the required shaft dimension, while keyways and tapped holes can also be added. This allows the pulleys to be precisely adapted to the specific drive and machine requirements.

What applications are V-belt pulleys with a cylindrical bore suitable for?

Cast iron V-belt pulleys with a cylindrical bore are used in a wide range of industrial drive systems. Typical applications can be found in mechanical engineering, plant engineering, conveyor technology, agricultural machinery, as well as ventilation and pumping systems. Thanks to their high load-bearing capacity and dimensional accuracy, they are suitable for both series-produced machines and spare parts and retrofit projects.
