Cylindrical roller bearings Cylindrical bore and special radial internal clearance
Ordering example
Cylindrical roller bearings are also available by agreement with a cylindrical bore. In the case of these bearings, there is no “K” in the short designation, see examples in brackets: ■ N10..K-M1-SP (N10..-M1-SP) ■ N10..K-PVPA1-SP (N10..-PVPA1-SP) ■ N10..K-HS-PVPA1-SP (N10..-HS-PVPA1-SP) ■ HCN10..K-PVPA1-SP (HCN10..-PVPA1-SP) ■ N19..K-M1-SP (N19..-M1-SP). If these bearings are planned for use at high speeds, the Application Engineering facilities should be contacted for assistance in order to achieve the correct design. The radial internal clearance tables for cylindrical roller bearings with a cylindrical bore contain standardised values. At high speeds, it may be the case that if the interference of the inner ring required to prevent the inner ring from lifting off the shaft is present, the cylindrical roller bearing with a cylindrical bore will run with preload after mounting. In this case, the radial clearance of the cylindrical roller bearing must be redefined with the assistance of Application Engineering. HCN1014-PVPA1-SP-R15-30NA
