Introduction about NSK double row Cylindrical roller bearing NN3009MBKR :
NSK’s double row cylindrical roller bearing’s rigidity makes them a perfect match for use in machine tool spindles. Tipically,single row and double row cylindrical roller bearings have either bore or a tapered bore. Double row culindrical roller bearings with a tapered bore are often mounted to the main shaft as a fixedend bearing.Simplicity in design and the ability to adjust radial internal clearance after mounting continue to make these bearings populor among machine tool users .
NSK offers several types of cylindrical roller bearings. Users can request and E44 configuration,which includes both lubrication holes and a machined lubrication groove on the outside surface of the outer ring. Types of bearings include the NNU type, which feathures double ribbed outer rings, and the NN type,which features excellent grease discharge during the initial running-in period,and helps promote steady oil flow throught the bearing.
For thin section type bearings , the narrower NN39 series is more suitable than the wider NN49 series due to less heat generation and greater roller stability.Machined brass cages are most common wth cylindrical roller bearings. NSK offers a roller guide pps resin cage for the NN30 series, and a PEEK resin cage, which is guided by the outer ring, for N10 series series of ultra high-speed single-row cylindrical roller bearings.
Types of cylindrical roller bearing:
.Single row cylindrical roller bearing: NU, NJ, NUP, NUB series
.Double row cylindrical roller bearings:NNU series
.Four row cylindrical roller bearing:FC series
.Single row full complement cylindrical roller bearing:SL18 series, SL 19 series
