What is the inner diameter of the pulley?

Before selecting a pulley, we recommend that companies measure the diameter of the two shafts at the equipment end, and then consider the size of the transmitted torque to determine which standard pulley to choose. The physical structure of the national standard pulley is different from that of the European and American standard pulleys, so there is a distinction in the selection. For example, the inner diameter of the same pulley has different definitions on national standard pulleys and European standard pulleys.
What is the inner diameter of the pulley?
Compared with the national standard pulley, the European standard cone sleeve pulley has an additional layer of cone sleeve inside. If we talk about the inner diameter of the pulley, the national standard pulley corresponds to the diameter of the master and slave shafts, while the inner diameter of the cone sleeve pulley actually corresponds to the outer diameter of the cone sleeve, and the inner diameter of the cone sleeve corresponds to the diameter of the master and slave shafts. After understanding this difference, companies should not be confused when selecting.

We have encountered many companies that originally used national standard pulleys, but due to product upgrades, they need to replace them with European standard pulleys. However, because they are not familiar with European standard cone sleeve pulleys, they have made a joke. If the enterprise has plans to replace the European standard cone sleeve pulley, it can contact us at Wuxi Boyang.
