- Volume: 1 kg can
- Also available in: 800 g cartridge, 10 kg bucket, 180 kg barrel
Benefits for your application
- Long-term availability and service life of components
- over a wide service temperature range up to 260°C
- when exposed to aggressive chemical agents and vapours
- when using sensitive plastic materials
- Tried and tested over many years in numerous industries and component types
- due to BARRIERTA base oils, which are made specifically to enable long-term stability
- backed by a large number of approvals and references
- due to availability in 4 different viscosity grades to suit various applications
Applications
- BARRIERTA I greases attain long service lives when used in rolling and plain bearings operating under high thermal stress.
- The fine thickener and the high oil content enable smooth running of bearings also at high speeds and ensure a long life of the lubricated components.
- Typical fields of application are in
- film stretchers
- textile stenter frames
- precision engineering
- clean-room engineering (e.g. microchip manufacture)
- The low vapour pressures of BARRIERTA I greases make them also recommendable for use in fine to ultra-high vacuum.
Application notes
- For optimum lubrication results, we recommend cleaning the friction points with white spirit 180/210 and then Klüberalfa XZ 3-1. For initial lubrication, the friction point must be clean and bright and free from particles.
