 Cylindrical Roller Bearings category 
 Cylindrical roller bearings are separable type bearings, installation and removal is very convenient. Cylindrical roller bearings can withstand greater radial load and applies to lead in high speed situations. These bearings allow the inner axis of the outer ring axis angle error (tilt) is very small, only 2 'to 4'. Therefore, the machining accuracy of the shaft and bearing relatively high and they are liable to uneven load or stress concentration in the contact area of ??the raceway. To amend the roller raceway contact bus can reduce the occurrence of stress concentration. Cylindrical roller bearing according to the number of columns equipped with rolling element can be divided into the different structures of the single, dual and multi-row cylindrical roller bearings. The bearings of the different structures is also reflected in the location of the design of ribs. One of the commonly used cylindrical roller bearings have the following forms: single row cylindrical roller bearings: Single row cylindrical roller bearings are separable bearings, easy installation and removal, the two rings can be a tight fit, amend the roller and roll Road between the contact line can reduce the stress concentration. Double row cylindrical roller bearings: double row cylindrical roller bearings are swimming in bearing its detachable makes installation and removal very easy. The two rings are a tight fit. Double row cylindrical roller bearings is almost not allowed to have a tilt angle.
