Spindle Bearings / Super Precision (P4S)


  • The B70.., B72.., B718.., B719..,HCB70.., HCB72.., HCB719.., HS70.., HS719.., HC70.., HC719.. series are manufactured as open and sealed versions.
  • highest accuracy, low noise level and low vibration (P4S)
  • absorb high axial forces from one direction as well as radial forces
  • can be installed in an X or O arrangement, for example, to absorb high axial forces in both directions
  • available with contact angle C = 15° or E = 25°
  • Range: from an inner diameter of 10 mm to an outer diameter of 300 mm

information on our labels

All spindle bearing packages have labels with additional information, which can also be found on the bearing rings.
ID: Deviation from bore diameter in µm

OD:

first number: deviation from the outer diameter in µm

second number: width deviation in µm

third number: deviation from the nominal protrusion in µm

packaging and markings

CSC spindle bearings are individually packaged for UL versions.

Bearing sets are welded together.

Markings and tolerances can be found on both the bearings and the packaging labels.
