Profiling techniques on the operation of SKF bearings

For some particularities of SKF bearings, for example, with the outer ring, inner ring, tapered bore, SKF bearings, whether the installation or removal must be the characteristics of attention to, to successfully complete the installation and removal process, so in order not to damage SKF bearings, we have the essential skills below to find out more:
1, the outer ring disassembly
Demolition of interference fit of the outer circumference of the shell in advance to set several outer extrusion screw with a screwdriver, side equally tighten the screw, while the demolition. These screw holes are usually covered with a blind plug, SKF Bearings, such as separation of bearings, several incisions in the housing block shoulders pads, press demolition, or tapping the demolition.
2, the cylindrical bore bearings demolition
The demolition of the inner pressure mechanical pull out the latest simple. At this time, pay attention to the inner ring to withstand the pulling force.
Large bearing inner ring disassembly hydraulic method. Oil pressure through the hole in the shaft, so that easy to pull. The width of SKF bearings hydraulic drawing fixtures and the demolition job.
NU-NJ type cylindrical roller bearing inner ring disassembly by induction heating. Local heating in a short period of time, so that the inner expansion after drawing.
3, the tapered bore bearings demolition
The demolition of the small band tight sleeve bearings, the file block support inner fastening to the shaft, the nut back several times, use the pad with a hammer to beat the demolition.
Large bearings, the use of hydraulic demolition easier, sending oil pressure in the tapered bore axis of the hole, so that the inner expansion, the demolition of the SKF bearing. Operation, the bearing may suddenly emerge, best use the nut as a file block as well.
