How to store the bearing pedestal

Imported bearings are precision mechanical objects that require strict storage and storage requirements due to the long transportation distance. It is necessary to control the temperature and relative humidity in the storage room to prevent excessive temperature changes (although seasonal temperature changes have little impact). Therefore, regardless of temperature, humidity, and packaging, they are implemented in accordance with the requirements of the specification. So how is it to store bearings scientifically?

How to store bearings scientifically?

1. Storage room requirements

(1) Clean and dry

(2) Prevent air flow

(3) If the relative temperature of the storage room is greater than 75%, air conditioning is recommended.

(4) Prevent vibration

(5) Keep the temperature constant (the temperature change within 48 hours shall not be greater than 3 ℃)

(6) Before leaving the factory, bearings are coated with anti rust oil, which can deteriorate if the temperature is too low or too high. The room temperature is between 0-25 ℃.

(7) Regular inspection: Regularly inspect bearing products every 10-12 months. If the oil seal package has rust, it should be reinstalled and sealed.

2. Temperature and humidity

(1) Bearings can be well stored in their original containers for a long time, as long as their relative humidity does not exceed 60% with little temperature change.

In clean air with a relative humidity below 50%, bare clean surfaces will not rust and corrode.

The possibility of corrosion increases with increasing humidity, especially when the relative humidity of the air is greater than 75%.

(2) After long-term storage of bearings with sealing rings or dust caps, the characteristics of bearing grease may be affected.
