Warehouse temperature
The bearings are coated with anti-rust oil before leaving the factory. If the temperature is too low or too high, the rust preventive oil will deteriorate. The room temperature should be controlled between 5-25 ° C, the maximum temperature should not exceed 30 ° C, and the minimum temperature should not be lower than 4 ° C. Otherwise, temperature control measures should be used and the warehouse should be protected from direct sunlight.
Warehouse humidity
Excessive humidity will rust the bearings, and the relative humidity of the warehouse should be between 45% and 60%.
Warehouse environment
The bearings are preferably stored separately. When they must be stored with other items, other items in the same place must not contain chemicals such as acids, bases or salts. The bearings should be placed on a wooden pallet 0.2m above the ground, away from the heating pipes and sinks and water pipes.
Periodic inspection
According to the national GB / T8597 "rolling bearing anti-rust packaging" standard, the rust-proof period of the bearing is divided into six months, one year and two years. The rust-proof period of bearings that require short-term installation is half a year, and the rust-proof period of ordinary mill bearings is one year. The calculation start date is based on the date indicated on the product factory certificate. According to the anti-rust requirements of bearing products, check every 10-12 months. If the oil seal package is found to be rusty, it should be resealed.
Bearings with an outer diameter of 200 mm or less can be placed horizontally on the shelf. Very large bearings should be stored horizontally on wooden pallets to avoid oval deformation of the bearings.
