Changeable Gear Ring

In a one piece turret there are always problems of the gear ring wearing out. 
The gear ring can wear out due to lack of lubrication, improper worm setting and overload.

If the turret is one piece and the gear ring wears out then it is very difficult to correct the situation.

A simple way to overcome this situation is to have a turret with a replaceable gear ring. In this case if the gear ring is damaged you need to simply replace it with a new one.
