Overview
Matched set of two super-precision, high-capacity, D design, single row angular contact ball bearings
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.
Key features
- Very high running accuracy
- Very high load carrying capacity
Typical applications
- Machine tool spindles and support shafts
- Pumps and compressors
- High-speed motors
- Precision gearboxes and robot drives
