Small NTN bearings widely use the press method of pressing the press. The pad is padded into the inner ring; the press is quietly pressed to the inner ring and the shaft is stopped tightly to stop. The outer ring is padded on the inner ring; Form the cause of indentation and crush on the raceway; so be sure to stop.
When operating; the best in advance on the cooperation surface oiling. In the occasion of the use of the hammer hitting the device; to pad the block on the inner ring. This practice has repeatedly become the reason for NTN bearing operation; so; only used The situation of small surplus; can not be used for large interference; or medium and large NTN bearings.
Such as deep groove ball NTN bearings and other non-detachable NTN bearings; the inner ring and the outer ring are required for the interference device; use the pad pad; use the screw or oil pressure, press the inner ring and the outer ring together. Self-aligning ball NTN bearing outer ring is easy to skew; even if it is not interference cooperation; it is also the best pad on the block device.
Such as cylindrical roller NTN bearing, tapered roller NTN bearing and other separate NTN bearings; can be equipped with the inner ring and the outer ring respectively to the shaft and the outer casing; when the inner ring and the outer ring are separately assembled; It is to steadily close the two; so that there is no contradiction between the two; barely press in will form a raceway surface damage.
