MASTER BUSHINGS

Master bushings are designed for sq and pin drive Kelly bushings from sizes 17 1/2" to 37 1/2" rotary tables. the pin drive allows the use of extended insert bowls to meet flush with the top of table which means better slip support and preventing damage to drill pipe. the sq drive bushing has a 4" deep recess to be used with the sq drive Kelly bushings. Short and medium style slips are used in the sq drive for shallower depth and drilling. 

CASING BUSHING & INSERT BOWL
CU, CUL and CB Casing Bushings are inserted directly into the rotary table and insure that the casing being run is perfectly aligned with the center of the hole. Models CU and CUL are solid bushings and Model CB is a split bushing.
