Rig Hoisting & Rotary Equipment
Rotary Tables and Master Bushings
Rotary Tables and Master Bushings for rotary drive, tubular suspension and transfer of torque through the rig floor where a conventional rotary table is required, with RFQ fields covering table opening, static and rotating load ratings, maximum torque and speed, gear ratio, drive arrangement, deck height and footprint, master and split bushing type, kelly-bushing interface, casing-bushing compatibility, lubrication, cooling, guards, braking or lock, controls, hazardous area and matching rig-floor drawings.
RFQ selection reference
Reference fields for quotation comparison. Final values must be confirmed in the signed manufacturer datasheet.
| Selection field | Typical input | Typical input | Typical input | Buyer note |
|---|---|---|---|---|
| Table capacity | Static load, rotating load and torque | Opening, height and speed range | — | Provide casing and drill-string program |
| Bushings | — | Master, split and kelly-bushing interfaces | Tubular size and insert range | Identify existing compatible equipment |
| Drive and installation | Power, gear ratio and lock duty | — | Rig-floor, lubrication and controls | Attach deck cutout and foundation drawing |
Product scope
Rotary Tables and Master Bushings are presented as a quotation-ready equipment family for rotary drive, tubular suspension and transfer of torque through the rig floor where a conventional rotary table is required. This page helps buyers compare technical offers; it does not promise one model, inventory position, load rating or certification. The final manufacturer must confirm the offered equipment against the rig load case, interface drawings, governing standard editions and signed datasheet.
Selection basis
The main inputs are table opening, static and rotating load ratings, maximum torque and speed, gear ratio, drive arrangement, deck height and footprint, master and split bushing type, kelly-bushing interface, casing-bushing compatibility, lubrication, cooling, guards, braking or lock, controls, hazardous area and matching rig-floor drawings. Load-path equipment cannot be selected from appearance alone. State whether the request is for new manufacture, replacement, remanufacture or spare parts, and provide maker, model, serial number, nameplate, service history, latest inspection report and dimensioned interfaces for installed equipment. For new projects, attach the rig arrangement, load summary, tubular program, utilities and environmental design data.
Trade and industry context
The cited UN Comtrade record is a broad machinery or hoisting-category export proxy used only to prioritize internationally traded product families. It is not a drilling-only market size or a shipment claim for this equipment. API references identify common technical and inspection boundaries; they do not prove that an unnamed supplier is licensed, certified, authorized or holding stock.
Documents and inspection
Define signed datasheets, general arrangement and interface drawings, structural or load calculations, material certificates, welding procedures, heat-treatment and NDT reports, dimensional inspection, pressure or functional test, proof-load records where applicable, inspection category, certificate of conformity, operating manual, maintenance plan and recommended spares. Verify the actual manufacturer, facility, certificate scope and standard edition before order release.
RFQ checklist
- •Equipment family, new/replacement scope, quantity and delivery date
- •Rated and operating loads, speed, torque, pressure or power cases
- •Rig, tubular, line, structural and utility interfaces
- •Materials, temperature, corrosion and hazardous-area requirements
- •Inspection history, NDT, testing, traceability and certificates
- •Destination, Incoterm, lifting, packing and transport limits
- •Target unit or package price and acceptable technical alternatives
Upload the nameplate, drawings, load cases, inspection records and project specification with the inquiry. Close every interface and certification deviation before comparing price or releasing the order.

Frequently Asked Questions
What information is required to quote Rotary Tables and Master Bushings?
Provide table opening, static and rotating load ratings, maximum torque and speed, gear ratio, drive arrangement, deck height and footprint, master and split bushing type, kelly-bushing interface, casing-bushing compatibility, lubrication, cooling, guards, braking or lock, controls, hazardous area and matching rig-floor drawings, quantity, destination, delivery target and required records. Attach nameplates, interface drawings and load cases for replacement equipment.
Are the displayed ratings guaranteed?
No. They are RFQ fields. The final signed datasheet, approved calculations, interface drawings, inspection and test records control the ordered equipment.
Can remanufactured or equivalent equipment be proposed?
Only when the buyer permits it. The offer must identify condition, manufacturer, serial number, inspection history, replaced parts, testing, certification scope and every technical deviation.
