LMGZ – Highly precise, stainless steel force measuring bearing

  • Measuring range 100:1, accuracy class ±0.3%
  • 11 sizes with nominal force from 33 to 25000 N (7.5 to 5620 lbf.)
  • Overload protection up to 20-times nominal force, full stainless steel

The force measuring bearings of the LMGZ-Series, designed for the measurement of tension on continuous material processing lines where live shaft idler rolls are utilized. The accuracy class of 0.3 % and the measuring range of 100:1 allows reproducible, highly precise measurements throughout the industry. The mechanical overload protection of up to 20-times the nominal force provides unsurpassed robustness. With the superior performance of the LMGZ-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.
