In the realm of industrial machinery and sophisticated automation equipment, linear guides emerge as pivotal moving components. To guarantee their enduring and stable operation, selecting the proper linear guide grease becomes paramount. In this context, we shall delve into the significance of appropriate grease for linear guides and explore the nuances of selection.

1.The Rationale Behind Using Linear Guide Grease

1.1 Mitigating Friction and Wear Linear guides are subjected to high frequencies and substantial loads, rendering friction and wear an inevitability. Grease with exceptional adhesion creates a robust, adhesive solid lubricating film, thereby reducing friction significantly, curtailing wear, and ultimately extending the service life of the guide rail.

1.2 Safeguarding Against Rust and Corrosion

Owing to the diverse environmental exposures, linear guides are vulnerable to moisture and chemical assault, leading to rust and corrosion. The judicious choice of linear guide grease can provide a robust shield against corrosion, ensuring the rails maintain their integrity.

1.3 Absorbing Shocks and Diminishing Noise

Grease embodies the qualities of shock absorption and noise reduction, endowing linear guides with enhanced stability during high-speed operation, minimizing noise, and elevating the degree of comfort of the working environment.

2. Selection Criteria for Linear Guide Grease

To fully actualize the potential of linear guides, selecting the optimal grease type and lubrication method, contingent on the configuration, load, and speed of the linear guides, becomes imperative. Notably, rolling guides, in comparison to sliding guides, exhibit minimal reliance on grease, necessitating reduced oil supply volumes and extended replenishment intervals, thereby appreciably reducing maintenance and management endeavors.

2.1 Adaptation to the Working Environment

Select grease congruent with the operational environment of the linear guide. For instance, in humid environments, a grease with robust water resistance should be employed, while in high-temperature settings, a grease with elevated heat resistance should be preferred.

Linear Guide Grease: The Key to Improved Mechanical Performance

2.2 Load and Speed

Under high-pressure and high-speed conditions, linear guides require lubricating greases with good mechanical stability and appropriate viscosity to ensure they are not easily squeezed out under heavy loads, thereby providing long-lasting lubrication. Maintenance interval: Different types of lubricating greases have varying maintenance cycles. Selecting a linear guide lubricant with a longer service life can reduce maintenance frequency and improve equipment operating efficiency.

2.3 Compatibility

When selecting lubricating grease, compatibility with the linear guide materials must be considered to avoid chemical reactions that could damage the guide.

3. What Is the Lubricant Replenishment Interval?

Even when high-quality linear guide lubricants are used, their performance gradually deteriorates over operating time, making regular replenishment necessary (typically, factory-sealed grease is exhausted after approximately 600 km of operation). The lubricant replenishment interval varies depending on operating conditions, but generally, grease should be replenished every 6 months. For machinery performing long-distance reciprocating motion, it is recommended to add lubricant every 3 months.

4. How to Apply Lubricant?

Fully inject the lubricant into grease fittings or oil holes until old grease is expelled. After application, perform a test run; excess linear guide lubricant will be pushed out to the exterior of the guide. This excess grease should be cleaned off before normal operation resumes. The amount of lubricant applied should be approximately 1/3 to 1/2 of the internal volume of the linear guide. When grease is first applied via the grease fitting, some loss may occur along the filling path, so this should be taken into account. Normally, motion resistance increases immediately after lubrication. After expelling excess grease and performing 10 to 20 reciprocating test cycles, the motion resistance will stabilize at a lower, consistent level.

Summary

Selecting the optimal grease is of paramount importance for ensuring the long-term, stable operation of linear guides. By gaining an understanding of the functions, characteristics, and considerations involved in grease selection, you can more effectively protect your linear guides, extend their service life, and enhance the operational efficiency of your equipment.
