– at very high operating temperatures of up to 260 °C
– when exposed to aggressive chemicals and vapors
– when other lubricants have a negative effect on plastic parts that rub against each other
Used in many industries and components for many years
– thanks to specially manufactured BARRIERTA ® base oils, designed for a long service life
– thanks to numerous approvals and references for a wide variety of applications
– Four consistency grades available for different requirements

Description

BARRIERTA ® is the oldest European quality brand of high temperature lubricants based on perfluoropolyether (PFPE) oil. Today, BARRIERTA ® is often considered synonymous with durability and temperature resistance. Specially manufactured raw materials and continuous development make BARRIERTA ® products
the first choice of experts around the world in many areas. The greases for long-term lubrication of the BARRIERTA ® L 55/0-3 series combine convincing resistance to high temperatures and aggressive media with good compatibility with plastics and elastomers.

Fields of application

Rolling and plain bearings operating in high temperature conditions One of the more highly valued properties of
BARRIERTA L 55 series greases is their resistance to extreme temperatures that occur during the operation of bearings and guides. Low evaporation of the grease increases its service life and reduces the frequency of lubrication.
Typical applications of BARRIERTA L 55/2 include:
– Conveyors (drive and deflection rollers)
– Wheel bearings for loading trolleys
– Calender bearings
– Fan bearings
– Film stretcher chain bearings
BARRIERTA L 55/2 is most commonly used for initial and long-term lubrication.

For operational lubrication, greases with a lower viscosity, e.g. consistency class 1 according to NLGI or lower, are recommended. Friction surfaces exposed to operating media
BARRIERTA L 55 greases are characterized by an extremely long service life even when exposed to aggressive media such as concentrated acids, alkalis, organic solvents and gases In addition to
resistance to operating media, BARRIERTA L 55/2 and BARRIERTA L 55 greases /3 are characterized by good adhesion and good sealing properties, thanks to which they can be recommended for applications including:
– fittings, accessories and installations in chemical industry plants
– elements of pneumatic systems
– level indicators, e.g. in fuel and chemical tanks
– seals (both static and dynamic)
– technological lifts

Food and pharmaceutical industry

All BARRIERTA L 55 series greases are NSF-H1 certified and thus meet the requirements of FDA 21 CFR § 178.3570.
Additional ISO 21469 certification makes it easy to prove compliance with your company’s hygiene requirements. 
This means that BARRIERTA L 55 white special greases can be used to lubricate friction surfaces when, for technological reasons, accidental contact with food products cannot be ruled out. This applies to rolling and sliding bearings and guides operating at high temperatures in devices such as:
– automatic baking ovens
– cooking and frying lines
– transport systems

Plastic Friction Surfaces

All BARRIERTA L 55 greases, regardless of NLGI grade, are inert to the vast majority of plastics. On the second page we have published the results of material compatibility tests with fluoroelastomers. However, it is recommended, especially for series applications, to confirm the compatibility of the lubricant with the material used in contact with it
