The application:
86 oil- lubricated rollerbearings from rolls in a kartonmachine.
The challenge:
Overcoming thermally cracked oil and extreme (oil) contamination.
The oil-lubricated roller bearings with integrated steam passages operate under high thermal loads, resulting in elevated operating temperatures. The lubricating oil within the bearing housing was subjected to thermal cracking and consequently became heavily contaminated. To maintain reliable bearing performance, approximately 600 liters of ISO VG 220 lubricating oil were replaced about six times per year.
Our solution:
A custom-designed 1,200-liter lubrication system was developed in-house, featuring variable-displacement pumps, active cooling, and integrated heating. This system is combined with the Triple R depth filtration unit, type OSCA306, for which TRIS B.V. serves as the authorized importer, to effectively remove (steam) moisture, as well as hard and soft particulate contamination and degradation by-products of the lubricating oil.
Financial advantages:
✅Reduced frequency of bearing and bearing housing cleaning
✅Extended bearing service life
✅Extended lubricant service life — replacement based on condition monitoring
Environmental and Climate Benefits:
✅Reduced reliance on external service providers
✅Fewer oil changes
✅Extended service life of bearings, pumps, and filters
