Grease, an ostensibly ordinary semi-solid lubricant, is in fact a critical guarantee for the stable operation of high-thrust servo electric cylinders, and can even be called the"lifeblood"of such cylinders.

It undertakes multiple vital roles in high-thrust servo electric cylinders—from reducing friction and wear, to dissipating heat and preventing rust. Every single one of these functions is crucial to the performance and service life of high-thrust servo electric cylinders.

In terms of friction reduction, grease acts like a high-performancelubricating barrier. When the lead screw of a high-thrust servo electric cylinder rotates inside the nut, grease forms a thin protective film with an extremely low friction coefficient on these metal surfaces. This film separates the metal components that would otherwise be in direct contact, significantly lowering the friction resistance between them.

This not only ensures smoother operation of the high-thrust servo electric cylinder, but also cuts down on unnecessary energy loss, much like injecting a boost of high efficiency into the machine’s operation.

Tests have shown that the friction coefficient of a high-thrust servo electric cylinder using suitable grease can bereduced several timescompared to an unlubricated one, leading to a marked improvement in operational efficiency.

Wear reduction is another key function of grease.

Prolonged high-speed operation and heavy-load work can easily cause severe wear to the internal components of high-thrust servo electric cylinders. The protective film formed by grease acts like a sturdyarmor, effectively buffering the interaction forces between components and reducing wear caused by friction.

Take the lead screw and nut as an example: without grease, frequent relative movement will gradually wear down the surface of the lead screw, resulting in reduced precision and impaired normal operation of the cylinder.

When high-quality grease is applied, however, the wear rate of the lead screw is drastically slowed down, its service life can beextended several times over, and the high-thrust servo electric cylinder is ensured to maintain high-precision operation even after long-term use.

Grease also plays a pivotal role in heat dissipation.

During operation, high-thrust servo electric cylinders generate substantial heat due to friction between components. If this heat cannot be dissipated in a timely manner, the internal temperature will rise sharply, which in turn affects the equipment’s performance and service life.

Grease boasts excellent thermal conductivity: it can quickly absorb the heat generated by friction and evenly transfer it to the surrounding environment, achieving effective heat dissipation and cooling.

In some high-power, high-thrust servo electric cylinders, the heat dissipation effect of grease is particularly pronounced. It can control the working temperature of the cylinder within a safe range, ensuring stable equipment operation.

Rust prevention is another indispensable function of grease that cannot be overlooked.

High-thrust servo electric cylinders typically operate in a variety of complex industrial environments. Moisture in the air, corrosive gases, and other factors can cause corrosion to their internal metal components. Grease can tightly adhere to metal surfaces, forming abarrier that isolates air and moisture, and prevents metal oxidation and rusting.

Even in harsh, humid, and dusty environments, high-quality grease can provide reliable rust protection for high-thrust servo electric cylinders and extend the equipment’s service life.

Using inappropriate grease may fail to form an effective protective film on component surfaces, leading to increased friction and wear, louder operational noise, reduced precision of the high-thrust servo electric cylinder, and even malfunctions such as jamming or seizing—all of which disrupt the normal operation of the entire equipment.

For instance, using non-high-temperature-resistant grease in high-temperature environments will cause the grease to soften and leak quickly, losing its lubricating and protective properties. In high-load working conditions, if the selected grease lacks sufficient extreme-pressure resistance, it cannot withstand the enormous pressure, leading to severe component wear and drastically shortening the service life of the high-thrust servo electric cylinder.

Therefore, selecting the right type of grease for high-thrust servo electric cylinders isextremely crucialand allows for no negligence whatsoever.
