Single row cylindrical roller bearings

Most of Cylindrical roller bearings are separable bearings, which are very convenient for installation and disassembly. Cylindrical roller bearings can withstand larger radial loads and are suitable for use in high-speed running situations.

Single row cylindrical roller bearings are composed of four parts: inner ring, outer ring, roller and cage. This type of bearing allows the angular error (inclination) between the axis of the inner ring and the axis of the outer ring to be very small, only 2’~4′. Therefore, the machining accuracy of the shaft and the bearing seat is relatively high, otherwise, uneven load or stress concentration will easily occur at the contact parts of the raceway. But after correcting the roller or raceway contact bus bar, the occurrence of stress concentration can be reduced. Single row cylindrical roller bearings include N, NU, NJ, NF, NUP, NFP, NH type.
