Electric NSK bearings NSK bearings as used in daily life is one of the most extensive, in its use of the process will inevitably encounter various problems, today we have electric NSK bearing cleaning process
Simple introduction.
In accordance with the time general motors at 2000 hours after the use of cleaning and oiling. There are two kinds of cleaning methods for NSK bearing:
A hot oil cleaning method, due to prolonged use, soft dry NSK bearing the anti rust oil or cream should be hardened, immersed in the hot oil 100 - 200 ℃, pliers NSK bearings, NSK bearings with oil brush clean. Do anti rust oil or soft paste was 100 - 200 ℃ heating to melt, easy from the gap of NSK bearing flushed. Sometimes as long as the NSK bearing in oil repeatedly shaking. Oil will flow through from the crevice.
In the spherical NSK bearing cleaning the old motor or import motor, should take the ball, bead frame, the inner ring in the horizontal transfer from after immersion in hot oil, short cylindrical roller bearing NSK cleaning should also roller, bead frame, the inner ring and the outer ring off.
In hot oil cleaning, oil temperature should not exceed 20 ℃. If using direct fire heating, care should be taken to prevent the burning of oil, NSK bearings should be hung in the pan, the bottom will cause overheating and reduce the hardness.
Two, like cleaning the NSK bearing soaked in kerosene 5 - 10 minutes, hand pinch the inner ring, the outer turning the other hand, NSK bearings on the anti rust oil or cream do you fall down. Then the NSK bearing into the oil cleaner, the use of soft scrub brush, put the ball and in the gap of the oil washed clean, then put 1 gasoline, remove and place them on a clean sheet of paper. Spherical ball bearing NSK and short cylindrical roller bearing NSK cleaning the ball, bead frame, the inner ring and the outer ring was torn off and cleaning.
Cleaning NSK bearings mounted on the shaft, mainly by pouring oil or oil injection method, oil can be easily cleaned after the first kerosene gasoline; oil is difficult to clean out, first with 100 - 200 ℃ hot oil leaching or oil spray gun, and then clean gasoline. Care must be taken not to use a sharp tool scraping the NSK bearings: hard grease stain or rust, so as to avoid damage to the NSK bearing rolling body and a groove ring parts of the finish, with a clean dry cloth cleaning NSK bearings.
