A 22~ 47 kW generator with a belt drive and a belt pulley end is SKF's nup309ecj,The remote is used in the fag 6309 C3, but the bearing life belt wheel end more than 1200 hours there will be abnormal sound, because nup309ecj did not seal, has been replaced with the two types of generator bearing, has now been raised with fag nup309ecj to replace the SKF oil 6309, is this position deep groove ball bearing for?
Of course not! Deep groove ball bearings and cylindrical roller bearings can bear radial force and axial force are not the same! If the bearing life is too short, it can check the shaft is not a problem, and the other is the installation method of bearing whether the problem, the use of SKF is genuine!
The deep groove ball structure is divided into two kinds of sealing and open structure. The open type means that the bearings are not sealed. The sealed deep groove ball is divided into dustproof sealing and oil tight sealing.The rolling element is a radial roller bearing of cylindrical roller. The internal structure of cylindrical roller bearing of the roller was 90 degrees vertical arrangement (which is also the cross roller bearing the name of the origin), interval retainer or isolation block is arranged between the roller and the roller can prevent between tilt or roller friction each other, effectively prevent the increase of rotational torque.
May not。Deep groove ball bearings and cylindrical roller bearings can bear radial force and axial force is not the same, if the bearing life is too short it can check the shaft if there are problems, and installation method of bearing is the issue of whether or not, the SKF is genuine.Deep groove ball bearings are the most common types of rolling bearings. A basic deep groove ball bearing consists of an outer ring, an inner race, a set of steel balls, and a set of retaining structures. Deep groove ball bearings are of two types, single row and double row.
