If you purchase tube or bar stocks, please follow the procedure below to impregnate finished products with lubrication oil before installation. If these bearings are stored for a long time or if the bearings are washed, re-impregnate before installation. Immerse the products into an oil bath. Heat the bath up to 100 ℃ to 110 ℃. Keep the temperature for 30 to 60 minutes until no more air bubbles come up. Cut the heat source and let it cool down to the room temperature. Take products out of the bath to install. If oil impregnation by heating is not possible, leave the products in the oil bath for 24 hours or more.
