MDSP MASTER BUSHING

17 1/2" and 20 1/2" Medium Duty Pin Drive Split Master Bushing are designed for shal low to medium depth service.

Extended API Taper
The MDSP Master Bushings have an extended APT taper in the bowls that provides 50 % more slip support than do square drive bushings.

Varco SDML slips, used in the MDSP master bushing are a proven combination that can handle drilling to 15,000 feet.

Note : Varco BJ does not recommend using split master bushings in rotary tables with more than 3/16" (5 mm) wear in the rotary table bore. Rebuild rotary bore or purchase a solid type bushing.

Units come complete with bit breaker, adapter plate and lifting sling.

MSS MASTER BUSHING

17 1/2 thru 27 1/2 Solid Body Square Drive Master Bushing is designed for all drilling opetions. A 4 inch deep recess accommodates a square drive kelly bushing. Developed for use when a 10,000 ft well was considered deep, the MSS still serves a useful purpose where a large slip backup area is not required. With the extended API insert bowl No.3, the MSS will handle 2 3/8 thru 8 5/8 inch OD Drill pipe, drill collars, tubings, and casing. Insert bowl No.2 can handle tubular goods 9 5/8 and 10 3/4 inches OD. The MSS design, with its solid body, retains the correct API taper for medium and short rotary slips (Varco's SDML and SDS) under all load conditions. These slips receive correct backup and hold tubulars uniformly. The solid outer body takes all transverse loads and provides proper backing for the split inserts bowls allowing the rotary table to rotate freely, unipaired by transverse loads.

CU, CUL AND CB CASING BUSHING

CU, CUL and CB Casing Bushing are inserted directly into the rotary table and insure that the casing being run is perfectly alinged with the center of the hole. Models CU and CUL are solid bushings and Model CB is a split bushing. All of the bushings accept bowls of different sizes to accommodate a wide rang of casing. Using CMS-XL or CP-S slips, since these bushing fit into the rotary Table, the casing string can be easily rotated during cementing operations
