NSK bearings removal and installation as well carefully. Be careful not to damage the bearings and parts, especially the interference fit bearing removal operation is difficult. So, at the design stage to consider in advance to facilitate the dismantling, removal tool based on the need to design is also very important. During disassembly, demolition drawings study, the order of investigation with the conditions of the bearing, in order to achieve disassembly jobs foolproof.
1, the outer ring of demolition
Removing the outer ring of the interference fit, prior to the extrusion screw with a screw, the side evenly tighten the screw, while demolition in some of the outer ring provided on the circumference of the housing. These screw holes are usually covered with blind plug, tapered roller bearings, separable bearings, shoulders set several incisions in the housing block, pad presses demolition, or gently beating removal.
2, the cylindrical bore bearing removal
The demolition of the inner ring, pull out the latest simple pressure mechanical. In this case, pay attention to the inner ring to withstand the pulling force.
Large NSK bearing inner ring removal by hydraulic method. Hydraulic be provided in the shaft hole, making it easier to pull. Width bearing the hydraulic method and drawing fixtures and demolition operations.
NU, NJ cylindrical roller bearing inner ring disassembly can take advantage of the induction heating method. Local heating in a short period of time, drawing in the expansion of the inner ring.
3, cone bearing removal
Demolition relatively small with adapter sleeve bearings, support the inner ring on the shaft stopper fastening nut reversed several times, use the pad with a hammer and beat the demolition.
Large bearings, the use of hydraulic demolition easier to send the oil pressure in the hole tapered bore axis, the inner ring expansion, demolition NSK Bearings. Operation, the bearing may suddenly emerge, the best nuts as well as a file block.
