Mobilux EP 2

Mobilux EP 2 NLGI 2 Lithium EP Grease

General-Purpose Extreme-Pressure Grease for Industrial Bearings, Bushings and Pins

Mobilux EP 2 is a high-performance NLGI 2 lithium grease designed for general-purpose industrial lubrication, including applications exposed to heavy loads, shock loading, moisture and water washout.

The formulation provides extreme-pressure and anti-wear protection while helping protect lubricated components against rust and corrosion. Mobilux EP 2 is recommended for multipurpose use in antifriction bearings, plain bearings, bushings and pins operating under normal industrial conditions.

Its NLGI 2 consistency makes it suitable for many manually greased and conventional grease-lubricated components where a general-purpose EP grease is specified.

General-Purpose Industrial Grease

Mobilux EP 2 is part of the Mobilux EP family of lithium extreme-pressure greases.

ExxonMobil recommends Mobilux EP 0, 1, 2 and 3 for many industrial applications, including equipment subjected to:

• High unit pressures
• Shock loads
• Vibration
• Moisture
• Wet operating environments

Within the series, Mobilux EP 2 is the NLGI 2 general-purpose grade.

NLGI Grade 2 Consistency

Mobilux EP 2 has an NLGI Grade 2 consistency.

NLGI 2 is one of the most commonly specified grease consistencies for industrial bearings and general equipment lubrication because it provides a balance of:

• Lubricant retention
• Mechanical stability
• Ease of application
• Protection of moving surfaces

The current Mobil data lists a worked penetration of approximately 280 under ASTM D217.

Always verify that NLGI 2 is the correct grease consistency for the equipment and lubrication system.

Bearings, Bushings and Pins

ExxonMobil specifically recommends Mobilux EP 2 for multipurpose lubrication of:

• Antifriction bearings
• Plain bearings
• Bushings
• Pins

These components can experience sliding, rolling, oscillating or shock-loaded contact that requires a grease capable of maintaining a lubricating film while resisting displacement.

Extreme-Pressure Protection

Mobilux EP 2 contains additives designed to provide protection where components experience elevated loads or shock loading.

Current published performance includes:

• Four-Ball Weld Load: 250 kgf
• Timken OK Load: 40 lb
• Four-Ball Wear Scar: 0.4 mm

These test results demonstrate the grease's load-carrying and anti-wear characteristics under standardized laboratory conditions.

Rust and Corrosion Protection

Industrial equipment operating around water, humidity or process moisture requires protection against corrosion as well as wear.

Mobilux EP 2 is formulated to help protect lubricated surfaces against:

• Rust
• Corrosion
• Moisture exposure

The current product information lists an SKF Emcor rust test result of 0,0 with distilled water.

Water Washout Resistance

Mobilux EP greases are designed to resist water washout, helping the lubricant remain on the component when moisture is present.

This makes Mobilux EP 2 suitable for compatible industrial equipment operating in:

• Wet environments
• Humid areas
• Locations subject to water exposure
• Applications where grease displacement by water is a concern

Water resistance does not eliminate the need for proper seals, inspection and scheduled re-greasing.

Operating Temperature

ExxonMobil currently lists a recommended operating-temperature range for Mobilux EP 0, 1, 2 and 3 of approximately:

-20°C to 130°C

Operation above the normal recommended range may be possible in certain applications if lubrication frequency is increased accordingly.

Actual grease life depends on bearing speed, load, temperature, contamination, grease quantity and equipment design.

Base-Oil Viscosity

Mobilux EP 2 uses a mineral base oil with typical viscosity values of:

• 160 mm²/s at 40°C
• 14.8 mm²/s at 100°C
• Viscosity Index: 91

The base oil is therefore in the ISO VG 150 viscosity range.

Grease itself is classified by NLGI consistency rather than ISO viscosity grade, so Mobilux EP 2 should properly be described as an NLGI 2 grease using an ISO VG 150-range base oil.

Centralized Lubrication Systems

Mobilux EP 2 should not automatically be selected for centralized lubrication systems simply because it belongs to the Mobilux EP family.

ExxonMobil specifically identifies Mobilux EP 0 and EP 1 as the grades suitable for centralized systems and applications where low-temperature pumpability is important.

Mobilux EP 2 is positioned as a general-purpose NLGI 2 grease.

If a centralized system requires an NLGI 2 grease, confirm pumpability and system requirements with the equipment manufacturer before use.

Current Specifications

• Volvo 97718
• DIN 51825:2004-06 KP2K-20

The current DIN classification supersedes the older KP2K-30 listing found in PSC's 2014 Product Data Sheet.
