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
