CYLINDRICAL ROLLER BEARINGS INTRODUCTION
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. This kind of bearing can make the angular error between the inner shaft and the outer shaft small, ranging from 2’to 4′. Therefore, it requires higher machining accuracy on the shaft and bearing seat; otherwise, the asymmetric load and stress will be concentrated on the position of the raceway. This situation can be improved by correcting the contact bus bars of the rollers or raceways. Cylindrical roller bearings are divided into single row, double row and multiple row cylindrical rollers according to different rows.
