A device for monitoring of roller bearings, in particular of the outer ring of roller bearings at clamping clips a to endless guide rails circumferential clamping clips chain of a tentering machine

摘要

Monitoring device is fitted to the outer rings of the low friction bearings on the clamp-plates of a clamp chain passing over an endless guide rail in a machine for biaxially stretching thermoplastic polymer sheet. It comprises sensors fitted in the area of contact of the rail and the surface of the outer ring for measuring a physical parameter.
