Industrial grease for humid environments


The GR-5000 is a superior quality grease for bearings which outperforms lithium, aluminum and polyurea base standard greases of the same viscosity.

Characteristics and Benefits

The GR-5000 unique formulation includes such elements as:

- Overbased calcium sulfonate complex
- Superior quality mineral base oil

This formula, maid from the latest thickener technologies, allows GR-5000 to reach an exceptional level of performance: it reduces friction, protects against rust, corrosion and oxidation, provides greater heat, moisture, wear and load resistance and enhances mechanical stability.

The superior qualities of the GR-5000 grease are not affected by temperature variations. Notable benefits from the use of the GR-5000 grease include less frequent lubricating jobs and substantial savings on maintenance costs.

Types of Application

The GR-5000 performs best in bearings with a top rotational speed of 3600 rpm: bearings for dryers, bearings exposed to water (wet end paper machine), calender rolls, bearings for heavy vehicles, electrical motors.

Directions for Use

Always use GR-5000 multi-purpose grease in reference to the equipment manufacturer's manual.


Whenever performing a grease change, make sure to validate the compatibility of the various greases used (refer to PROLAB's grease compatibility chart).
