ntn triple-sealed bearings for bearing units these reliable triple-sealed bearings are dustproof and waterproof they ensure a longer bearing life even when exposed to heavy airborne dust and splashes of foul water features better dustproofing and waterproofing ensure a longer bearing life triple-sealed bearings feature a secure bearing seal with three lips this special seal offers reliable dustproofing and waterproofing superior to those of standard bearings used in bearing units in addition it ensures a longer service life even when exposed to heavy airborne dust and splashes of foul water patent pending reduces maintenance cost a bearing life longer than that of a standard bearing unit configurations means extended maintenance intervals greatly reduced maintenance costs of inspection relubrication replacement etc and increased availability of machinery decreases price of the bearing unit and contributes to more compact machinery the triple-sealed bearing unit replaces conventional c
