Keeping in view the requirement of shallow to a medium depth well these models are available API-7K specification suitable for 27-½" Rotary Tables. The SSP (Square Drive Split Type) model are having a standard taper of Bowl No. 3 as per API to handle tubular size from 2.3/8” to 8.5/8”. This allows the use of extra-long SDXL slips required for a heavier load. Rise in taper by 2-½”, makes all slips rise by 2-½” which makes slip handling easier. This rise of slips distributes the load uniformly in the bushing resulting in less wear & tear of table bore. Additionally, this taper provides 50% more slip support resulting in better load managing capability. 27½” Master Bushing designed to handle string load up to 500 ton.
