330102-40-70-10-02-CN Probe Armored Bently Nevada

Long-Reach Armored 8mm Probe with 3/8-24 UNF Thread

The Bently Nevada 330102-40-70-10-02-CN belongs to the trusted 3300 XL series. We design this long-reach armored 8mm probe for accurate displacement and vibration measurements in deep machine casings and bearing housings. The 4.0 inch (102mm) unthreaded tip provides extended reach for deeper industrial applications.
