igus® bearings ensure a maintenance-free bottling system

Lubrication-free polymer bearings from igus® increase efficiency at the Chimay Trappist beer brewery in Belgium
The renowned Belgian brewery Chimay, known for its traditional Trappist beer, relies on maintenance-free spherical bearings from igus® in its bottling plant. By replacing rusty, seized ball bearings with lubrication-free igubal H3 bearing inserts, the brewery was able to increase efficiency and reduce maintenance.
The Chimay Brewery is one of thirteen breweries in the world that produces Trappist beer, made by monks. Interestingly, the majority of their profits are intended for social projects[1]. Brewed at Notre-Dame de Scourmont Abbey in the Belgian province of Hainaut, Chimay produced around 18.5 megalitres of beer in 2018. The high production requirements posed special challenges for the bottling plants, especially due to frequent failures and the seizing of conventional metallic ball bearings to shafts. The replacement of a defective ball bearing could take up to one and a half days, which unfortunately led to production losses. As part of a project to optimise the filling lines, Chimay turned to igus® to find a permanent solution to this problem. After an extensive series of tests and optimisations, the igubal H3 bearing proved to be the optimal choice and since the changeover in September 2022, these bearings have shown very little wear.
Lubrication-free, safe and easy to clean
The igubal H3 bearings offer many advantages that significantly improve the brewery’s production process. They are made of tribologically optimized high-performance plastics. This makes them lubrication-free, maintenance-free and corrosion resistant. Even at speeds of 200 rpm, the bearing material is working well within design limits. The igubal bearing inserts are much easier to install and replace than metal ball bearings, which drastically reduces maintenance times. In addition, there is no longer any wear-related shaft damage, which extends the service life of the entire system. Another advantage is the high resistance of the igubal H3 bearing inserts to chemicals. Despite regular cleaning processes, they show no signs of damage. Due to these characteristics, the line achieves an impressive speed of 55,000 bottles per hour. After a successful test phase on three different production conveyors, Chimay has already ordered 150 additional bearing inserts to replace the remaining ball bearings. “With the igubal H3 bearings, we have been able to solve the most important problem on our conveyor systems and significantly extend the service life of our systems,” says Vivien De Schryver, maintenance technician at Chimay.
