High-speed Sealed Angular Contact Ball Bearings

ZYS High-speed sealed angular contact ball bearingsHigh-speed sealed angular contact ball bearings performance1.When machine tool spindle runs under highly polluted condition, solid contaminants or cooling fluid entering the bearings is the main cause of bearing premature failure. There by the lubricant efficiency will be reduced, while bearing temperature will rise and abrasion will be accelerated. To solve the above problems effectively, ZYS produces a kind of sealed ball bearing, the high-speed sealed angular contact ball bearings with lifelong and clean lubrication grease. The types and performance of ZYS angular contact ball bearings ZYS angular contact ball bearing seriesStructuresDimension seriesBore size rangePerformanceHigh precision angular   contact ball bearing718 C718 AC 719 C719 AC 70 C70 AC 72 C 72 AC718:10～360mm 719:8～460mm 70: 8～380mm 72: 8～220mmHigh speed;Large loading capacity;Suit for grease or oil-mist lubricationHigh speed angular contact ball   bearing(incl.
