How to choose the right pulleys for a good functioning?
The service life of Codica wire ropes can be considerably increased by careful selection of the pulleys and rope construction, the main criteria being :
- The geometry of the groove bottom
- Ratio of groove bottom diameter to rope diameter
- The surface finish of the groove bottom
- The material of the pulleys
- Rope construction

Codica pulleys have been specially designed for operation on steel cable. Manufactured from injected polyamide material.
Three main types of pulleys are available: with a simple bore, with a self-lubricating bearing or with a bearing for more intensive use.
We recommend coupling the pulleys to a flexible cable of 7X7 or 7X19 construction. The rope should ideally be sheathed in polyamide 12 to achieve high endurance cycles.
