Ballfanglager für Maschine (ZTOM60)

Bearing 1.product:ball retainer bearings 2.Istalled spares requested : (1).Guide bush Material GCR15/YB9 heat treatment, hardness HRC62-66, roughness of surface 0.05 (2).Axis Material treatment GCR15, YB9, heat treatment, hardness HRC62-66, roughness of surface 0.05 (3).Mounting dimensions Dmax+2d-Dmin=0.01 0.02mm Advantages and Applications: There is a gap between hole and axis with traditional relative motion. It exists comparatively large kinematic friction coefficient. After using steel ball retainer to keep a gap between axis and hole. The small amount full steel balls go through the gap. So the kinematic accuracy is taller than before. The rolling resistance replaces the slipping resistance.Rolling is flexible. The friction coefficient is small. The useful time is longer than before. Although the non oil or adding oil bushing can match the axis in rolling and moving situation, kinematic accuracy is low. If using rolling bearing, it only satisfies the relative movement situation.The steel ball retainer can meet above-mentioned demands. It has been widely used in cold punching die carrier, machine tool accessories and same high-precision axial direction path movement situation. Tech Data:
