Guide carriage with piezoresistive layer for load measurement

摘要

The present invention is a guide carriage (20) used for linear rolling bearings (10), where the guide carriage (20) is a separate track insert (30) having a carriage track (32) with respect to the rolling element (22). To be equipped. According to the present invention, the track insert (30) is provided with a piezoresistive layer (50) and an electrode (51), whereby an external load applied to the guide carriage (20) is measured.
