Double Row Cylindrical Roller Bearing With Tapered Bore And Lubrication NNU4926 K/W33
Super-precision double row cylindrical roller bearing with tapered bore and lubrication feature
Super-precision double row cylindrical roller bearings in the NNU 49 series are designed to accommodate heavy radial loads and high speeds, while providing a high degree of stiffness. Having three flanges on the outer ring and no flanges on the inner 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.
