7018 ACD/P4ADTMatched set of two super-precision, high-capacity, D design, single row angular contact ball bearings

SKU: 7018 ACD/P4ADTMatched set of two super-precision, high-capacity, D design, single row angular cont

These matched sets of two super-precision, high-capacity, D design, single row angular contact ball bearings are available in a variety of arrangements. They are designed for high-load capacity and relatively high speed operation and, compared to the equivalent SKF B and E design high-speed bearings, are best suited for heavier loads.
