Klüber MICROLUBE GL 261 High-Load Grease for Heavy Machinery Maintenance

? Product Overview

Klüber MICROLUBE GL 261 is a high-performance assembly and running-in paste developed for heavy machinery maintenance under extreme loads.

It is specifically designed to protect metal surfaces during assembly, overhaul, and initial operation, where conventional greases and oils are unable to provide sufficient lubrication. The solid lubricant technology ensures reliable protection against wear, galling, and fretting corrosion, even under boundary lubrication conditions.

For maintenance teams working with construction equipment, mining machinery, and other heavy-duty applications, MICROLUBE GL 261 delivers proven reliability and reduced downtime.

⚙️ Key Benefits for Heavy Machinery Maintenance

• Excellent load-carrying capacity
  Protects components under extreme surface pressure during assembly and start-up.

• Prevents galling and scuffing
  Reduces the risk of seizure on press fits, pins, bushings, and splines.

• Effective under boundary lubrication
  Solid lubricants remain active when oil films are insufficient.

• Anti-fretting corrosion protection
  Ideal for oscillating or vibrating components in heavy equipment.

• Supports controlled and safe assembly
  Helps achieve consistent torque and reduces rework during maintenance.

? Typical Heavy Machinery Applications

Klüber MICROLUBE GL 261 is widely used in maintenance and overhaul of:

• Press-fit pins and bushings

• Splined shafts and couplings

• Heavily loaded threaded connections

• Sliding and guiding surfaces

• Construction machinery (excavators, loaders, cranes)

• Mining and quarry equipment

• Heavy industrial machinery and steel plant equipment

It is especially suitable for low-speed, high-load, and intermittent motion applications common in heavy machinery.

? Maintenance Challenges Solved

Common problems in heavy machinery maintenance:

• Assembly damage and surface scoring

• Component seizure during press fitting

• Fretting corrosion caused by vibration

• Short service life after overhaul

How MICROLUBE GL 261 helps:

• Forms a durable lubricating film under extreme pressure

• Minimizes metal-to-metal contact during installation

• Reduces wear during running-in phase

• Extends service life of critical components

? Recommended Use in Maintenance Operations

• Apply a thin, even layer to cleaned contact surfaces

• Suitable for assembly, running-in, and long-term lubrication under heavy load

• Do not mix with incompatible greases unless compatibility is confirmed

For optimal performance, follow equipment manufacturer guidelines and maintenance best practices.
