WHY BALL BEARINGS?

Conventional lifting points with asymmetrical force introduction can only be adjusted in the direction of force. 

This is sufficient to align the lifting point in the corresponding tensile direction for multiple strand suspensions. This already has decisive advantages over the rigid DIN eye bolt, since the DIN eye bolt can become loose in a dangerous manner, which requires that the load-bearing capacity has to be considerably reduced. 

In practice, the need for lifting points, which can also be used for rotating and turning loads, has become increasingly apparent. Conventional lifting points with symmetrical and unsymmetrical force introduction without ball bearings are not suitable for turning operations due to the considerable friction within the lifting point. Self-loosening of the bolt cannot be excluded under these circumstances, even with the required tightening torque. 

Lifting points without ball bearings can become loose when the load rotates. The VLBG can be adjusted in the direction of force – but must not be turned or rotated under full load.
