S7020 ACE/HCP4AQBCA

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

These sets of four matched super-precision angular contact ball bearings are available as universally matchable bearings or in preconfigured arrangements.

Sets of four bearings arranged in tandem need to be mounted against a single bearing, or a set of bearings in tandem, to achieve the desired preload. All the other arrangements are available in different preload classes and correct mounting results in preload within a predetermined range, without the need for shims or similar devices. The bore and outside diameters of the bearings are matched to within a maximum of one-third of the permitted diameter tolerance, to provide better load distribution than single universally matchable bearings.

  • Very high running accuracy
  • High axial and radial stiffness
  • High axial and radial load carrying capacity
  • Non-contact seals
  • Integral sealing prolongs bearing service life
