NSK Bearings in the course to reach the bearing life or because of some external factors lead to premature bearing recession, the need for timely removal of the replacement. Removal and installation of NSK Bearings, all professionals need to use professional tools.
NSK Bearings demolition order in accordance with the bearing installation instructions on the demolition drawings, professional demolition tools step by step disassembly.
Different bearing demolition is not the same, the following specific categories:
A bearing outer ring demolition methods
Demolished NSK bearing outer ring needs to be set in advance on the circumference of the case several outer extrusion screw with a screwdriver, side equally tighten the screw, while the demolition. Separation of bearings tapered roller bearings, etc., set up a few incisions in the housing block shoulders, use the pad to use the press demolition, or tapping with the demolition.
2, the cylindrical bore bearings demolition methods
For a generally cylindrical bore bearing, the method of demolition is relatively simple, you can beat with pressure mechanical pull out is to make it uniform force, can not damage shaft.
Large bearing inner ring disassembly hydraulic method. Oil pressure through the hole in the shaft, so that easy to pull. The width of NSK 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 methods
The small tapered bore bearings demolition can take advantage of the file block support inner ring and the nut back a few times, use the pad with a hammer to beat the demolition.
Large NSK Bearings can use the hydraulic method, by increasing the oil pressure, so that the bore expansion, which can be easily demolished to complete.
