1. Also called slewing rings or slewing Bearings, they are installed between two surfaces to keep parts aligned and support axial and radial loads.

2. additional hoists and slewing gear units and adaptation of the roller bearing slew ring and rope pulleys to the requirements of bulk handling under extreme conditions.

3. The self-Centralising troughing set is designed as a series of rollers arranged in a trough positioned onto the supporting transom which itself is fixed to a slewing ring which permits rotation

4. A second input of the digital adderreceives a negative digital error signal and the output of the digital adder provides a digital capacitance measurement signal corrected for an error current which is integrated across the reference capacitor in the gain mode due to the slewing of the operational amplifier.
