Single row cylindrical roller bearings and double row cylindrical roller bearings distinction

Single row cylindrical roller bearings are separable bearings, easy installation and removal, two rings may be a tight fit, the contact line of the rollers and raceways between the modified can be reduced stress concentration. Double row cylindrical roller bearings are non-locating bearing, separable makes its easy installation and removal. Two rings can be a tight fit. Double row cylindrical roller bearings almost not allowed to have an inclination angle. When installing the rolling ball bearings and cylindrical roller bearings, all parts are installed concentric must be strict, so as not to skew the inner sleeve of the jacket. The only way to ensure concentricity to note that boring process, installing or removing the force can not be transmitted directly through the rollers and the cylindrical ring wall.
