In order to prevent bearings from rusting during transportation and storage, precision bearings are usually packed with a thin layer of anti-rust oil on the bearing surface. In order to prevent poor bearing lubrication due to the incompatibility between lubricating oil or grease and anti-rust oil, it is recommended that precision bearings be carefully cleaned after opening the package. If conditions permit, the operator can wear it once. Non-toxic plastic gloves, do not touch the bearing directly with your hands.

(1) Clean, high-purity gasoline should be used for bearing cleaning fluid, preferably at least No. 90 gasoline;

(2) The cleaning of the bearing can be completed in two steps. Prepare two clean containers, pour enough cleaning liquid, and place a metal mesh pad in one of the containers. First, soak the bearings taken out of the packing box in a dry container with mesh pads, or use a brush to remove the anti-rust oil film on the surface of the bearings, and then perform final cleaning on the bearings in the second container, cleaning while rotating. Note that the cleaning solution should be replaced in time during the cleaning process to ensure the cleanliness of the cleaning solution. Sealed bearings are not suitable for cleaning and can be installed and used directly;

(3) After cleaning, the bearing should be air-dried or dried naturally. After the residual cleaning fluid of the bearing is completely air-dried, proceed to the subsequent operation;

(4) If the bearing is lubricated with oil, it should be installed under the condition that the bearing is not rotated as much as possible. If the bearing is grease lubricated, proceed with subsequent grease filling and installation procedures;

(5) In order to facilitate the smooth installation of the bearing, it is recommended to apply a thin layer of lubricating oil on the installation surface of the bearing.
