S7010 ACE/HCP4A

Super-precision, high-speed E design, single row angular contact ball bearing with seals

These super-precision, high-speed E design, single row angular contact ball bearings, with 25° contact angle, with seals, accommodate radial and axial loads acting simultaneously, where the axial load acts in one direction only.

They are designed to accommodate very high speeds. Compared to the equivalent SKF B design high-speed bearings, have a slightly higher speed capability and can accommodate heavier loads.

  • Very high running accuracy
  • Accommodate very high speeds
  • Accommodate relatively high radial loads and large unilateral axial loads
  • Non-contact seals
  • Integral sealing prolongs bearing service life
