Medium Duty Split Type Pin Drive Master Bushing - Brochure

Keeping in view the requirement of shallow to medium depth well these models are available API-7K specification suitable for 17-1⁄2", 20-1⁄2"and 27-1⁄2" sizes of Rotary Tables. The PSP (Pin Drive Split Type) and SSP (Square Drive Split Type) models are having 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 heavier load. Rise in taper by 2-1⁄2”, makes all slips rise by 2-1⁄2” 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. 271⁄2” Master Bushing designed to handle string load upto 500 ton.
