S7004 CE/HCP4ADGA

Matched set of two super-precision, high-speed E design, single row angular contact ball bearings with seals

These matched sets of two super-precision, high-speed, E design, single row angular contact ball bearings with seals are available in a variety of arrangements.

Compared to the equivalent SKF B design high-speed bearings, these have a slightly higher speed capability and can accommodate heavier loads.

  • Very high running accuracy
  • Accommodate very high speeds
  • Non-contact seals
  • Integral sealing prolongs bearing service life
