Potentiometers are almost ubiquitous, from household televisions and audio equipment to various electronic instruments and industrial control devices. Although it may seem like a small component, it directly affects the adjustment feel, signal stability, and service life of the entire device. In the long-term use of potentiometers, the selection of lubricating grease is often a key factor determining the stability of performance.
Essentially, a potentiometer is a component that combines precision electrical contact with mechanical rotation. During use, the rotary rod and shaft need to rotate repeatedly while ensuring stable contact, uniform damping, and consistent feel. Without suitable lubrication or if the wrong grease is selected, problems such as stiff rotation, inconsistent feel (sometimes light, sometimes heavy), increased noise, and even accelerated internal wear are likely to occur, affecting signal output and service life.
High-quality potentiometer lubricating grease usually has the following characteristics:
Good adhesion: It can fill the micro-gaps between components, effectively reducing noise and vibration;
Excellent shock absorption, buffering, and damping performance: Ensures long-term stable adjustment feel;
Superior lubricity, water resistance, and mechanical stability: Not easy to lose or separate oil;
Good compatibility with common potentiometer materials such as plastics and rubber: Will not cause corrosion or material deformation.
It should be noted that different types of potentiometers and different usage scenarios have significant differences in requirements for damping feel and viscosity. If the damping is too small, the feel tends to be loose; if the damping is too large, it will affect adjustment sensitivity. Therefore, the grease used for potentiometers emphasizes "matching" rather than a single indicator.
To meet the needs of different working conditions, Baoxing Lubricants has launched a variety of special lubricating greases for potentiometers with different viscosity grades, which can cover various application scenarios such as home appliances, audio equipment, instruments, and industrial control. It also supports customized development according to customers' actual structural and feel requirements, helping customers improve product quality and consistency from the source.
