Ship crane slewing ring bearing supply and installation — single-row, double-row and triple-row types with class-approved fitting.
Professional Slewing Ring Bearings Supply & Installation by Active Ship Management at Chittagong Port, Matarbari Port, Mongla Port, Payra Port — Bangladesh.
Active Ship Management supplies and installs slewing ring bearings for ship deck cranes, provision cranes and gantry cranes. Slewing bearing renewal is a major job requiring boom support, correct torque and precise re-alignment — our team handles the full scope on-board or in dry dock.
