PIV chains for variators

PIV chains run in continuously variable chain drives, known as variators. Each link contains a pack of thin, sliding laminations that adapt to the grooves in the conical discs and mesh with them.

PIV chains - drive transmission in a variator without slip

The drive is transmitted by positive engagement rather than friction, so the chain does not slip even under high load, and the set speed remains constant. Replacing a worn chain restores adjustment accuracy and lets you keep using a working variator instead of buying a new one. The sizes correspond to the designations used in PIV variators, which makes selection easier.

PIV chains in the sizes of popular variators, with matching links

PIV chains in several sizes corresponding to the size of the variator. Matching connecting links can be found in the Connecting links group, and offset links for selected sizes in the Offset links group.

Frequently asked questions about choosing the size of a PIV chain

How do I choose the size of a PIV chain?

The chain size depends on the size of the variator. Read it from the variator's rating plate or from the designation on the old chain.
