Cylindrical roller bearing

Cylindrical roller bearings SKF super-precision cylindrical roller bearings are characterized by: High speed capability High radial load carrying capacity High rigidity Low friction Low cross-sectional height These bearings are therefore particularly well suited for machine tool spindles where the bearing arrangement must accommodate heavy radial loads and high speeds, while providing a high degree of stiffness. SKF super-precision single row cylindrical roller bearings have a higher speed capability than double row bearings while double row bearings are more suitable for heavier loads. Designs and variants SKF manufactures super-precision single row and double row cylindrical roller bearings in three different designs and series. The bearings, which can accommodate axial displacement of the shaft relative to the housing in both directions, are separable, i.e. the bearing ring with the roller and cage assembly can be separated from the other ring. This simplifies mounting and dismounting, particularly when load conditions require both rings to have an interference fit. SKF super-precision single row cylindrical roller bearings in the N 10 series (fig. 1) have, as standard, a 1:12 tapered bore (designation suffix K). A tapered bore is preferred because the taper enables accurate adjustment of clearance or preload during mounting. The bearings have two integral flanges on the inner ring and no flanges on the outer ring. To improve lubricant flow, these bearings can be supplied with a lubrication hole in the outer ring on request.
