3,266 Published by admin Oct 22,2021

nsk koyo bearing is a kind of precision mechanical object, plus the long distance of transportation, the bearing storage and custody requirements are very strict, the temperature and relative humidity of the storage room must be controlled to prevent the temperature change (but seasonal temperature changes affect Not big). Therefore, no matter the temperature, humidity, and packaging are implemented in accordance with the requirements of the specification. So what is the scientific storage of nsk koyo bearings?

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 is not more than 3℃)
(6) nsk koyo bearings are coated with anti-rust oil before they leave the factory. If the temperature is too low or too high, the anti-rust oil will deteriorate. The room temperature should be controlled at 0-25℃.
(7) Regular inspection: According to the rust-proof regulations of nsk koyo bearing products, regular inspections are carried out every 10-12 months. If rust is found in the oil seal package, the oil seal package should be re-packed.

2. Temperature and humidity
(1) As long as the relative humidity of the warehouse does not exceed 60% and the temperature does not change much, nsk koyo bearings can be stored in the original packaging for a long time.
In clean air with a relative humidity of less than 50%, rust and corrosion will not occur on the bare clean surface.
As humidity increases, the possibility of corrosion will increase, especially when the relative humidity of the air is greater than 75%.
(2) After long-term storage of nsk koyo bearings with sealing rings or dust caps, the characteristics of nsk koyo bearing grease may be affected.

3. Storage of large nsk koyo bearings
The correct storage method of large nsk koyo bearings can only be placed horizontally, that is, the bearings are placed in a horizontal position, and the entire side of the bearing ring should be supported.
If the nsk koyo bearing is placed in a vertical position, due to the relatively small thickness of the bearing ring, the weight of the bearing ring and rolling elements may cause permanent deformation of the bearing.

The scientific storage of nsk koyo bearings is very important. If improper storage causes the bearing to rust or corrode, it is not good. Even if there is no surface damage, it is possible that such and other failures may occur during the operation of the bearing, so The storage of bearings must be taken seriously.
