NSAR premium 6217 bearing is made in China and 6217 bearings Made of bearings steel,bearings steel with higher and more uniform hardness and abrasion resistance.The most rare is that of bearings steel with ultra-high hardness at the same time,have very strong elasticity.The assurance of hardness can prolong the service life of bearings.
The 6217 Bearing storage:
NSAR bearings are packed in each individual packaging box with inner seal plastic polymer bag.
Under proper storage facilities with relative humidity not more than 60%, these bearings can be stored for many years. However we strongly advised our customers that all lubricating properties of the grease with which the bearings are filled may deteriorated if the bearings have been stored for a long time, Most anti-rust mechanism can last for 12 months period or more depending on the packaging and storage conditions. We strongly advised bearings to be stored under their original packaging conditions protected from dust and against corrosion and environment conditions before any application.
