S7009 CD/HCP4ADBA

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

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

They are designed to accommodate heavy loads at relatively high speeds under low to moderate operating temperatures.

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