Self-align Turning Rolls

Self-align rolls are designed for non-symmetrical gravity center parts, or with a lot of connections. Also for processes that involve a constant change in the working diameters or parts to be turned with very thin walls. They don’t require any kind of adjustment to be able to use parts with different diameters. Another very common application is in conical parts, since it reduces a lot their movement when turning. Not recommendable for applications over 100 tons weight.

Weldtech Positioning Rolls are designed to work in extreme conditions, very hardy, the only ones with a three year guarantee. We have a stock with more than 20 sets of different measurements. You will find in this catalog the most common, but not the only ones. We are able to adapt any value, weight capacity, wheel type, higher and lower speed, minimum and maximum diameter, spark proof motors for paint and sandblast. Let us know about your application and so we can customize your design.
