Wedge belts
Wedge belts have a deeper, narrower profile than classical V-belts, so they transmit more power in less space. Choose a section, then the belt type, or search by the code on your old belt, such as SPZ1250.
Choosing the right wedge belt
Three things decide which wedge belt you need: the section, the length and the type of belt.
- Section and lengthWedge belts are sized by datum length in millimetres. A code like SPZ1250 is an SPZ section belt with a 1250mm datum length.
- Wedge or classical?Wedge belts are deeper for their width. An SPZ is 8mm deep against 6mm for a classical Z, so measure the depth as well as the width.
- Smooth, cogged or maintenance freeSmooth SP belts suit most drives. Cogged XP belts run cooler on small pulleys, and maintenance-free belts never need re-tensioning.
