It is a scorching May afternoon at a manufacturing plant in Gujarat. Inside, a large motor drives a fan beside a hot process line. Its bearings have been running warm for weeks, and the maintenance engineer can hear a faint hum that was not there before.
A few hundred kilometres away, in a cold storage warehouse, a conveyor bearing faces the opposite problem. In the chilled air, its grease has stiffened, and the motor strains every time the line starts.
Neither problem is unusual. Across Indian industry, bearings live through blazing summers, chilled storage rooms, and long, non-stop running hours.
Two machines, two extremes, and one common cause: a grease pushed beyond what it was made for. Pal Syntholix Grease from Palco is a synthetic grease engineered for bearings that face extreme temperatures. This article explains what it is, how it works, and when a synthetic grease makes sense.
What Is Pal Syntholix? A Synthetic Lithium Complex Grease
Pal Syntholix is a synthetic lithium complex grease made by Paras Lubricants Limited under the PALCO brand. It is designed for medium- to heavy-duty industrial applications and has a beige appearance.
It brings together three key elements:
- PAO synthetic base oils, which improve both low- and high-temperature performance
- A tailored, highly shear-stable lithium complex soap, which gives excellent structural stability
- Specifically selected EP and AW additives, which help reduce noise, vibration, and shocks
Its standout figure is a wide operating temperature range of -50°C to 180°C.
Pal Syntholix is available in NLGI 2 and NLGI 3 grades. Its key published characteristics are:
How This Synthetic Grease Works
Many conventional greases use mineral base oils derived from crude oil. PAL SYNTHOLIX uses PAO synthetic base oils, designed to deliver reliable lubrication across a wide temperature range.
What PAO Means in One Line
PAO (polyalphaolefin) is a man-made base oil built for consistency, and it generally copes with both cold and heat better than mineral oil.
Because it is made to a controlled design, PAO tends to behave more predictably than mineral oil as temperatures change.
In Pal Syntholix, this blend of synthetic oils improves both the low- and high-temperature properties of the grease. That is why one product can cover such a wide temperature range.
A Thickener That Does Not Give Up
Grease is oil held in a thickener. Pal Syntholix uses a highly shear-stable lithium complex soap. “Shear stable” simply means the grease keeps its structure even after the bearing has churned it for a long time, instead of thinning out.
What EP and AW Additives Do
EP (extreme pressure) additives protect metal surfaces under very heavy loads. AW (anti-wear) additives reduce everyday wear. In Pal Syntholix, they are specially selected to also help reduce noise, vibration, and shocks.
Lower Friction, Cooler Running
Pal Syntholix offers a lower coefficient of friction (COF), which is simply a measure of how easily surfaces slide over each other. Its published COF is 0.08 at 75°C. Palco states that it reduces the operating temperature in the heavily loaded contact zone of ball bearings.
Key Features and Benefits of Pal Syntholix
Performance from -50°C to 180°C
Few greases cover such a wide span. From cold storage and winter starts to hot motors and process equipment, Pal Syntholix is built to keep lubricating across the range.
Smooth Starts in the Cold
Pal Syntholix offers low running torque at low temperatures. In plain words, bearings turn more easily when cold, so motors do not have to strain at start-up.
Think of a conveyor in a cold storage facility starting up after a weekend shutdown.
Quieter, Smoother Machines
NVH stands for noise, vibration, and harshness. Pal Syntholix is highly shear-stable and helps reduce NVH, which is valuable for electric motors and precision bearings where quiet running is a sign of health.
Reduced bearing noise can indicate effective lubrication, but noise and vibration should also be assessed alongside operating temperature and maintenance conditions.
Lower Friction Even When Hot
Pal Syntholix offers a significant reduction in friction even at high temperatures. Less friction generally means less heat and less wear.
Long-Lasting Protection
A durable lubrication film, good oxidation stability in harsh environments, and excellent anti-rust properties all contribute to longer life for both the grease and the machine. Palco highlights extended grease life as one of the product’s key benefits.
For machines that are hard to reach or costly to stop, longer grease life is a real advantage.
For general-purpose bearing lubrication in suitable applications, PALCO also offers MegaLife multipurpose grease. Review its technical specifications to confirm that it meets your equipment’s operating requirements.
Strong Load Protection and Water Resistance
Its published weld load is 315 kg, a laboratory measure of how much load a grease can take before the test parts seize. Low water washout figures add protection where moisture is a concern.
Where Pal Syntholix Works Best
Tapered and Cylindrical Roller Bearings
Pal Syntholix is recommended for tapered and cylindrical bearings where performance requirements cannot be met by mineral oil greases. These are often the most demanding bearings in a plant.
Tapered roller bearings carry both radial and axial (thrust) loads, while cylindrical roller bearings handle heavy radial loads. Both are common in heavy industrial machinery.
Electric Motor Bearings
Electric motor bearings are among its listed applications. For motors that run for long hours, smooth, quiet, and cool running is exactly what maintenance teams want.
In many plants, motors run around the clock driving pumps, fans and conveyors. A bearing failure in one of them can stop an entire line, so the grease in these bearings deserves careful thought.
Automotive Steering Joints, Hubs and Chassis
Pal Syntholix can also be used in automotive applications, including steering joints, wheel hub bearings and chassis points.
For vehicles that face extreme temperatures, a synthetic grease at these points can offer an extra margin of protection.

Practical Tips for Using Synthetic Grease
These general tips help any synthetic grease deliver its full value. The equipment maker’s recommendations should always come first.
Know When Synthetic Grease Makes Sense
Synthetic grease is most valuable where mineral greases struggle: very low or very high temperatures, heavily loaded bearings and machines where noise and friction matter. For mild, low-load duties, a conventional grease may be enough.
Choose the Right Grease Grade
NLGI 2 is a little softer, while NLGI 3 is firmer. The equipment manual, bearing type, speed, and mounting usually decide which suits best. When unsure, sharing the application details with Palco’s technical team helps.
Apply Grease Correctly
- Clean grease nipples and fittings before greasing.
- Avoid mixing greases. When switching, remove the old grease as far as practical.
- Do not overfill bearings, especially in electric motors, where excess grease can cause heat build-up.
Store Synthetic Grease Properly
Keep containers closed and stored in a cool, dry, covered place. Use clean tools so that dust and moisture stay out.
Monitor Bearing Condition
Rising bearing temperature, new noises, or vibration are early warnings. Tracking them helps set the right re-lubrication schedule for each machine.
Many plants use simple tools such as temperature guns and vibration checks during routine rounds, which make these early warnings easier to catch.
Choosing the Right Synthetic Grease
Extreme temperatures, heavy loads, and extended operating hours demand reliable lubrication. PAL SYNTHOLIX is a synthetic lithium complex grease designed for heavy-duty applications and has an operating temperature range of -50°C to 180°C. It is suitable for selected roller bearings, electric motor bearings, and automotive steering knuckles and hubs.
