What are the requirements for the installation environment of plastic coated bs bearings

When installing Plastic Coated BS Bearings, it is crucial to ensure a highly clean environment. Due to the electrostatic adsorption characteristics of the plastic coating surface of the bearing, dust, metal particles, oil mist and other suspended impurities in the environment may adhere to the coating surface or penetrate into the bearing during installation. These tiny particles will not only cause abrasive wear in the later operation, but may also cause seizure, jumping or abnormal noise in severe cases. Therefore, it is recommended to carry out installation operations in a clean work area that complies with ISO 14644 standards, and ensure that the installation platform, tools and operators are equipped with electrostatic protection devices to reduce the risk of particle adhesion.

In addition, the temperature and humidity in the installation area should be kept within a stable range to avoid inconsistent thermal expansion or condensation of materials caused by environmental changes. Although plastic coating materials have a certain temperature adaptability, if the ambient temperature is too high during installation, it may cause local softening of the coating or degradation of surface performance; conversely, if the ambient temperature is too low, there may be a risk of brittle cracking, especially when the coating thickness is thin or rigid polymers such as POM and PA are used. The ideal installation temperature should be maintained between 18℃ and 25℃, and the relative humidity should be controlled between 40% and 60%, which not only helps prevent surface corrosion caused by condensation, but also avoids the risk of adhering contaminants. When operating in a high-humidity environment, moisture may enter the bearing interface, affecting the lubrication system and even causing rust on metal parts, especially in Plastic Coated BS Bearings with stainless steel or ceramic hybrid structures.

In addition, vibration sources in the installation environment should be avoided or isolated as much as possible. The structure of Plastic Coated BS Bearings before installation is relatively sensitive, especially when the coating is not fully fitted or cured. The continuous presence of micro-vibration sources in the environment may cause fatigue stress accumulation in the bearing, resulting in surface cracks or peeling during subsequent use. In industry applications with high-precision assembly requirements, such as medical equipment, semiconductor equipment or high-end food processing machinery, small vibrations may also affect the matching accuracy of the bearing and surrounding accessories, thereby reducing the overall operating efficiency.

Finally, the installation environment must have good anti-static and anti-chemical measures. Some plastic materials such as PTFE and PPS are highly sensitive to solvents. If there are volatile chemicals such as paint, alcohol, acidic and alkaline cleaning agents in the environment, their vapors may react with the coating to degrade or cause structural swelling, especially in high temperature or poorly ventilated environments. Therefore, the storage and use of chemicals should be strictly controlled in the bearing installation area. If necessary, a special installation room should be set up or a local exhaust device should be used to improve the air quality to ensure that the bearing is assembled in a pure atmosphere.
