Measuring wheels 500 mm

Measuring wheels made of aluminium, cross-knurled or polyurethane coated with different tread structures for length measurement of different materials, very good running properties, highest measuring accuracy, reduced mass due to optimised shaping.

the specified temperature depends on the area of application

Due to the large number of possible application and operating conditions, no guarantee can be given for the behaviour of a polyurethane compound in all areas of application. It is the responsibility of the user to test the material selection in a specific application to determine its intended use.
