Lubrication monitoring solution for linear guides prevents unplanned downtime

02 August 2021

By installing the Schaeffler DuraSense lubrication monitoring solution on its vehicle handling systems, automotive machine maker Hager Sondermaschinenbau GmbH has seen a range of benefits, including the prevention of unplanned downtime due to insufficient lubrication, extended time intervals for general overhaul, and early detection of defective lubricators.

Hager is using the DuraSense lubrication monitoring solution on linear axes in large portal handling systems, which are being developed for car body production at major automotive manufacturers around the world. Hager intends to use this solution to reduce unplanned downtime for its customers on their production lines.

Challenge for Schaeffler

Hager produces portal handling systems that weigh up to 90 tonnes, for renowned automotive manufacturers. The maintenance, general overhaul and assembly of the portal handling systems is undertaken by around 80 employees at its site in Möttingen, Germany.

In 2012, Hager designed a new type of clamping frame replacement system for car production. The KFG3 portal handling system, also known as a framer, moves vehicle clamping equipment (clamping frames) with the aid of linear axes. Up to 50 vehicles per hour can be produced using the KFG3. The monorail guidance systems used in the linear axes are considered among the most system-critical components in the framer. If these fail, the entire production line is shut down. For this reason, Hager was searching for a monitoring solution that could not only be retrofitted to the linear axes, but which the company could also use to optimise the general overhaul intervals. As a result, Hager decided to seek assistance from Schaeffler...
