The inspection of the adjacent components (housing and shafts) should include a check of dimensional and geometrical accuracies as well as the surface roughness of the bearing locations. In the case of tapered locations it is also necessary to check the roundness, the taper angle and the straightness of the tapered surface outline.
IBC high-precision rolling bearings for high-precision tool spindles are manufactured with great care under the cleanest possible conditions, subjected to intensive checks and inspections, and provided with high-quality packaging to prevent damage and contamination during transport. Attention should be paid to having a clean and dust-free workplace for installation so as to achieve the best possible running behaviour. The penetration of fine airborne dust or very fine chips would affect both the accuracy and service life of the high-precision rolling bearings.
