Bearing Warehouse
Temperature: Bearings are coated with anti-rust oil before leaving the factory. High-precision bearings are even stored in wooden boxes or plastic boxes. Excessively low or high temperatures can cause the anti-rust oil to deteriorate. The room temperature should be maintained between 5-25°C, with a maximum of no more than 30°C and a minimum of no less than 4°C. Otherwise, temperature control measures should be implemented, and the storage room should be protected from direct sunlight.
Bearing Warehouse Humidity: Excessive humidity can cause bearings to rust. Bearing warehouses should be dry and well-ventilated, with relative humidity maintained between 45% and 60%.
Bearing Warehouse Environment: Bearings should ideally be stored separately. If they must be stored with other items, the other items should be free of chemicals such as acids, alkalis, and salts. Bearings should be placed on wooden pallets at least 0.2m above the ground, away from heating ducts, sinks, and water pipes. Keep the oil and wax coating intact during storage. Avoid mixing bearings with other items or tools to prevent collisions, deformation, and rust.
Regular Bearing Inspections
According to the national standard for "Rust-Proof Packaging for Rolling Bearings," bearing rust protection periods are divided into six months, one year, and two years. Bearings intended for short-term installation and use have a six-month rust protection period. For general bearings, the rust protection period starts from the date marked on the product's factory certificate. Regular inspections should be conducted every 10-12 months, in accordance with bearing rust protection regulations. If rust is detected in the oil seal packaging, repack it.
Store Bearings Horizontally
Bearings with an outer diameter of less than 200mm can be stored horizontally on shelves. Extra-large bearings should be stored horizontally on wooden pallets to prevent elliptical deformation.
