How to choose a model
A few checks narrow the NAB models below to the ones worth quoting.
- Reading the dimensions
- The Dimensions column lists the size range, meaning the diameter or thickness of the material, that each model is specified for. For example, NAB 100 covers 1.0–50.0 mm (0.039–1.97 in).
- Match the material
- Models in this series differ in the materials they are listed for (profile). Check the Materials column before you compare sizes.
- Match the size
- Pick the model whose range contains the diameter or thickness of your material. The NAB series spans 0.6–80 mm (0.024–3.15 in) in total. If your size sits on the boundary between two models, ask us which suits your material better.
- Choose the roll count
- NAB is offered with 2 and 4 rolls. Compare the roll count with your application, and ask our sales team if you are unsure which one fits.
Tolerance and line speed also affect the right choice. Send your material, size, tolerance and line speed with your quote request and we will confirm the model with Witels-Albert.
