In the previous article, I have given you popular science on how to clean the bearings, so how to confirm whether the bearings are cleaned? The 37-year bearing manufacturer will analyze it for you below: After the bearing is cleaned, carefully observe that there will always be some remaining oil in the inner and outer rings, rolling elements and gaps in the ball bearing. When testing, first use a clean micrometer to scrape off the remaining oil, wipe it on the thumb, and slowly rub it back and forth with the ring finger. If there is a rustling sound between the fingers, it means that the bearing is not cleaned and should be washed again. Finally, hold the bearing in your hand, pinch the inner ring tightly, turn the outer ring to rotate horizontally (large and medium-sized bearings can be placed on the assembly table, the inner ring is cushioned, the outer ring is suspended in the air, clamp the inner ring, and rotate the outer ring), To meet the standard of flexible rotation, no hindrance, and no vibration. After the bearing is cleaned and lubricated, it should be placed on the assembly table, with a clean cloth or paper pad on the lower side, and a plastic film on the upper side, and it cannot be placed directly on the ground or on the table. Covered or sealed bearings, or bearings coated with anti-rust and lubricating dual-purpose grease, do not need to be cleaned before installation because the lubricating grease is applied during production. Only when the torque is accurate can the rotation be stable! This article is from Co., Ltd., a bearing manufacturer for 37 years, please indicate the source and link (http:// )
