THE TRUNCATED BALL WITH A BLIND HOLE IS A LOW-COST MODIFIED BALL WITH HIGH MOUNTING STRENGTH. THIS VERSION IS USUALLY PINNED AND GLUED TO HOLD IT IN POSITION. THIS DESIGN IS OFTEN EMPLOYED IN PRODUCTION APPLICATIONS WHERE LARGE NUMBERS OF KINEMATIC COMPONENTS REQUIRE MAXIMUM ECONOMY. THE REDUCED PROFILE HEIGHT, THE ADDED STABILITY OF THE FLAT BASE AND THE HIGHER LOAD-CARRYING CAPACITY ARE ALL GOOD SELLING POINTS FOR THIS DESIGN.
