LMGZD – Highly precise, stainless steel force measuring bearing with a measuring range > 500:1

LMGZD
Features
  • Measuring range > 500:1
  • 3 sizes with nominal force from 33 to 6000 N (7.5 to 1350 lbf.)
  • Overload protection up to 10-times nominal force, full stainless steel

The force measuring bearings of the LMGZD-Series, designed for the measurement of tension on continuous material processing lines where live shaft idler rolls are utilized. The measuring range of 500:1 allows reproducible, highly precise measurements on widely varying web widths and materials. The mechanical overload protection of up to 10-times the nominal force provides unsurpassed robustness. With the superior performance of the LMGZD-Series, accurate tension readings are obtained even with low web wrap angles and high roll weights. For installations where a Pillow Block mount is required the optional bracket can be utilized.
