Description
Description
GSA-4000 is a high-performance, multi-purpose grease specifically designed for equipment
maintenance in the food and pharmaceutical industries. Its calcium sulfonate thickener provides
exceptional protection against wear, heavy loads, and moisture, surpassing most conventional
lithium, aluminum, or polyurea-based greases.
Features and Benefits
Registered with NSF for incidental food contact (H1), GSA-4000 benefits from a thickener whose
intrinsic properties enhance protection against wear and corrosion. Thanks to its excellent
physico-chemical performance, it is suitable for a wide range of applications, including bearing
lubrication up to 3500 RPM, use in automated/centralized lubrication systems, and protection of
mechanical components exposed to highly humid environments.
Applications
GSA-4000 is recommended for lubricating bottling equipment, mixers, bearings, conveyors, and
plain bearings. It offers a service temperature range from –20 °C to 120 °C.
For any technical or compatibility questions, please contact your Prolab Technolub
representative.
Directions for Use
Use GSA-4000 in accordance with the equipment manufacturer’s recommendations.
