Product Details

Super Precision Cylindrical Roller Bearing With Tapered Bore And Lubrication Feature

Super-precision double row cylindrical roller bearing with tapered bore and lubrication feature

non-locating bearing, double row, with tapered bore, taper 1:12, separable, with cage

Super-precision double row cylindrical roller bearings in the NN 30 series provide a unique balance between load carrying capacity, rigidity and speed. Having three flanges on the inner ring and no flanges on the outer ring, the bearings can accommodate axial displacement in both directions. The separable design simplifies mounting and dismounting, particularly when load conditions require both rings to have an interference fit. The tapered bore enables accurate adjustment of clearance or preload during mounting.

Very high radial load carrying capacity
High rigidity and high running accuracy
Minimize noise, vibration and heat generation
Accommodate axial displacement in both directions
Lubrication feature
