VZ and L: a replacement may have a different number of links
The same width or both designations appearing on a product do not imply the same construction or number of links. When replacing a chain, verify the exact supplied type, length and suitability for the variable speed drive.
Shortening, lengthening and splitting a chain
We will assess modification based on the construction, chain condition and availability of suitable connecting parts.
Have the option of opening the chain for installation and supply of a connecting pin, split pin or other parts confirmed for your specific order.
How to identify an unknown chain
- Send a legible chain designation and a photograph of the variable speed drive nameplate.
- Count the links and measure the pitch between the centres of adjacent pins, width and height. State your measurement method.
- Attach an overall view, side profile, details of the plates and chain joint, ideally with a scale.
- State the quantity, required length or modification and whether you need the chain open for installation.
