Rotating joints are precision mechanical parts that experience extreme forces in industrial processes. Some parts, such as the bearings and seals, wear out over time and as a result of the rotational cycles. In this case, maintenance work is necessary and must be done before the machine shuts down.

The risk of a break in operations must therefore be taken into consideration as soon as any malfunction appears. Each part must be closely monitored. The slightest breakdown can have major consequences for your entire production line. Given this economic and operational reality, we have developed an expert assessment and maintenance service, the goal of which is to extend the lifetime of your swivel fittings.
