Reduced operating and maintenance costs
Are you changing trunnion liner fasteners due to damage? Or, having to replace the entire trunnion liner due to localized lining wear?
Decrease operating costs through optimized wear components associated with the trunnion liner upgrade. The trunnion liner upgrade has been developed primarily to reduce maintenance costs through its multi-component configuration. The multi-piece design optimizes load conditions through the trunnion liner thereby improving fastener durability. Dividing the trunnion liner into multiple pieces enables the replacement of the consumable component only, consequently reducting ongoing consumable costs.
Improved process availability
Have you experienced mill downtime due to lengthy trunnion liner replacement or trunnion liner removal for trunnion bearing replacement?
Reduce lost production time with the trunnion liner upgrade. The multi-component liner design enables quick removal of the trunnion liner retaining ring, allowing unrestricted access to the bearing without the need for removing the entire lining.
The Metso trunnion liner upgrade is old for new replacement components and can readily be supplied to the site; however, as with all retrofit devices, we recommend a site inspection to confirm that the trunnion is still in as-designed condition. This will ensure the validity of the product design for your site to reduce the risk of unforeseen issues during installation and plant downtime.
All site visits will be scheduled to the mutual convenience of your plant’s designated contact person and a Metso representative. Metso shall remain reliant on the customer to ensure that the plant is available for the inspection visit at the scheduled time.
