It’s early morning in a large process plant, and the maintenance team is on its rounds. Rows of electric motors hum, and big fans move air through the system at full speed. The technicians listen carefully as they walk, because a change in that steady hum is often the first sign of a bearing in trouble.
High-speed bearings have a problem that slow, heavy bearings rarely face. The faster they spin, the more the grease itself resists the motion. That resistance turns into friction and heat. Pack a fast motor bearing with the wrong grease, and it can run hot simply because of what is inside it.
The Pal Lithcom EP-200 Series from Palco is a family of specially complexed lithium greases designed for high-speed bearings. This article explains, in plain language, what it is, how it works, and where it fits best.
What Is Pal Lithcom EP-200 Series? A Lithium Complex Grease for High-Speed Bearings
Pal Lithcom EP-200 Series is a range of premium lithium complex greases made by Paras Lubricants Limited under the PALCO brand. Palco states that these greases are built for exceptional performance and durability in high-speed bearings, helping cut equipment downtime and the total cost of ownership.
The series covers six grades, 200, 220, 221, 222, 222(M) and 223, all built on the same core strengths:
- Lithium complex thickener, which gives high thermal and lubrication film stability
- Low frictional torque, which helps high-speed bearings turn with less resistance
- Excellent shear stability, which helps the grease keep its consistency under constant working
- High adhesion and water repellence, which help the lubricating film stay in place in hot, wet conditions
- Rust protection, which guards precision bearing surfaces
The Pal Lithcom EP-200 Series is offered in NLGI 00, 0, 1, 2 and 3 grades. Its key published characteristics are:
How High Speed Bearing Grease Works
Grease for a fast bearing has a different job from grease for a slow one. Here is how the Pal Lithcom EP-200 Series handles speed and heat, without the jargon.
What Is Frictional Torque?
Frictional torque is the extra effort needed to turn a bearing because of the grease inside it, so lower torque means less wasted energy and less heat.
The Pal Lithcom EP-200 Series is designed to reduce the frictional torque generated at high speeds. For a motor running all day, that matters.
What Is Shear Stability?
Shear stability is a grease’s ability to keep its consistency even after being worked over and over by fast-moving parts.
High-speed bearings shear grease constantly. In lab testing, the NLGI 2 grades change by only +15 points and the NLGI 3 grade by +17 points after 100,000 strokes of working. Roll stability results of 6 to 8% for the NLGI 1, 2, and 3 grades point to the same conclusion.
Understanding the Six NLGI Grades
NLGI grades measure firmness, and in one line, NLGI 00 is a soft, semi-fluid grease, while NLGI 3 is firm.
The 200 grade is NLGI 00, 220 is NLGI 0, 221 is NLGI 1, 222 and 222(M) are both NLGI 2, and 223 is NLGI 3. Every grade uses the same lithium complex thickener and 220 cSt base oil, so a plant can pick the consistency that suits each machine and lubrication system.
What Do EMCOR and Wear Scar Tests Mean?
The EMCOR test runs bearings with grease and water to check for rust, and a rating of 0.0 means no rust was found. The wear scar test measures the mark left on steel balls under load, so a smaller scar means better wear protection.
Grades 220 to 223 carry an EMCOR rating of 0.0 with distilled water, and grades 221 to 223 show wear scars between 0.42 and 0.47 mm. Every grade has a published weld load of 315 kg.
Key Features and Benefits of Pal Lithcom EP-200 Series
Smoother, cooler high-speed running
Reducing frictional torque is the headline benefit. Less resistance inside the bearing generally means less heat and less wasted power, which helps motors and fans run the way they were designed to.
Thermal Stability and Lubrication Film Protection
The series is designed to work efficiently in hostile high-temperature environments. Thanks to high adhesion, it can maintain an efficient lubrication film even at high temperatures, and it offers high thermal and lubrication film stability.
Water Resistance and Washout Protection
Palco states that the grease prolongs bearing life even in the presence of water, cutting fluid, and fumes. In the water washout test at 79°C, losses range from 2.4% for the 223 grade to 3.8% for the 221 grade.
Shear Stability and Consistency Retention
With excellent shear stability and higher mechanical stability, the grease is designed to resist softening and thinning over long running hours. That helps keep bearings protected between greasing intervals.
Rust and Corrosion Protection
Excellent rust protection, EMCOR results of 0.0, and a 1B copper strip corrosion rating across the grades help protect bearings and nearby copper parts. Palco also states that the series is oxidation- and corrosion-resistant.
Good Pumpability
Good pumpability helps the grease travel through lubrication lines and reach each bearing as intended.
Applications of High Speed Bearing Grease
Electric motor bearings
Electric motor bearings are first on the application list. Motors in pumps, compressors, and conveyors run at speed for long hours, so low frictional torque and shear stability are exactly what their bearings need.
For other industrial bearing applications, explore PALCO AP-3 Grease, which is designed for electric motors and ball and roller bearings.
OD fans and hot roller mills
OD fans and hot roller mills combine speed with heat. The series is recommended for both, where a stable lubrication film at high temperature is critical.
Precision bearings in steel, paper and chemical plants
Precision bearings demand a clean, stable grease. Palco recommends the series for precision bearings and for use across the steel, paper and chemical industries, where Palco states it works in hostile chemical environments.
Automotive wheel bearings
The series is also designed for automotive wheel bearings, which see high speeds and heat on long drives.

Practical Tips to Get the Most from High-Speed Bearing Grease
These general tips help any high-speed bearing grease deliver its full value. The motor or equipment maker’s recommendations should always come first.
Choosing the right grade
Start with the motor nameplate or equipment manual, which usually states the grease type, quantity, and interval. Pick the NLGI grade the maker specifies, and match it to the lubrication system in use. When in doubt about which of the six grades fits, sharing the details with Palco’s technical team is a sensible step.
Applying it correctly
- Measure the quantity. In high-speed bearings, too much grease is a common cause of heat build-up, because the bearing has to churn the excess.
- Where the motor has a grease relief or drain plug, open it while greasing so old grease can escape.
- Clean the fitting first, and use a dedicated, clean grease gun.
- Avoid mixing different greases. When switching, purge as much of the old grease as practical.
Storing it well
Keep containers tightly closed in a cool, dry, covered place, away from dust and process fumes. Precision bearings are sensitive to dirt, so use a clean scoop or pump and older stock first.
Monitoring Bearing Performance
During routine rounds, check motor bearing temperature, noise, and vibration. A bearing that runs hot just after greasing may simply be overfilled. Adjust intervals to the real speed, temperature, and duty cycle.
Choosing the Right High Speed Bearing Grease
In high-speed equipment, grease is not just protection. It also affects friction, heat, and energy use. Pal Lithcom EP-200 Series brings together a lithium complex thickener, low frictional torque, strong shear stability, and high water repellence across six grades from NLGI 00 to NLGI 3. For electric motors, fans, hot roller mills, precision bearings, and automotive wheel bearings, Pal Lithcom EP-200 Series is a high-speed bearing grease worth a closer look.
