S7019 ACDGA/HCP4A

Super-precision, high-capacity, universally matchable single row angular contact ball bearing with seals

These super-precision, high-capacity, single row angular contact ball bearings, with non-contact seals, accommodate radial and axial loads acting simultaneously, where the axial load acts in one direction only.

They are designed to accommodate heavy loads at relatively high speeds under low to moderate operating temperatures. Being universally matchable, they can be used together in arrangements to provide effective load sharing, without the use of shims or similar devices.

  • Very high running accuracy
  • Very high load carrying capacity
  • Universally matchable
  • Non-contact seals
  • Integral sealing prolongs bearing service life
