KLUBER MICROLUBE GBU-Y 131: The High-Performance Grease Built for Water, Humidity, and Heavy Loads

1. Product Overview

MICROLUBE GBU-Y 131 is engineered with a semi-synthetic base oil and a metal complex soap thickener, offering a powerful combination of water resistance, mechanical stability, and long-term protection against wear and corrosion. This formulation makes the grease especially reliable for equipment exposed to humidity, water spray, or outdoor conditions.

2. Key Features

• High load-carrying performance
  The metal-complex thickener structure enhances pressure absorption and mechanical stability.

• Excellent water resistance
  Maintains lubricity even under direct water exposure or high humidity.

• Strong corrosion protection
  Prevents rusting and surface degradation, extending component life.

• Stable consistency
  Homogeneous, fibrous texture ensures uniform lubrication.

• Wide temperature range
  Works reliably from –25°C to +150°C, suitable for year-round industrial use.

• NLGI 1 consistency
  Easier flow at low temperatures and compatible with centralized lubrication systems.

3. Recommended Applications

MICROLUBE GBU-Y 131 is suitable for equipment requiring high mechanical stability under wet or humid environments, including:

• Rolling and plain bearings under medium to high loads

• Outdoor industrial machinery exposed to weather or moisture

• Water-exposed components such as pumps, conveyors, and processing equipment

• Ski lift rope grips — a proven long-term application where humidity and mechanical load are critical factors

This versatility makes it a strong choice for industries such as transportation, lifting systems, machinery maintenance, and general manufacturing.

4. Advantages for Industry Users

• Longer equipment life due to superior corrosion protection

• Reduced downtime thanks to reliable water-resistant lubrication

• Lower maintenance frequency due to stable, durable grease film

• Flexible application: brush, spatula, grease gun, or cartridge use supported
