MSP Master Bushing
MSP Master Bushing – API-7K-certified rotary table component for seamless handling of 3½"–20" drill pipes and collars. Engineered with H2S-resistant alloy steel and high-temperature boron coating, it withstands extreme drilling environments (-40°C to 200°C) and reduces wear by 60% in abrasive/sour gas conditions. Its modular design allows quick interchangeability with standard rig rotary tables, cutting downtime by 30% during pipe tripping. Precision-machined grooves ensure zero slippage under 500-ton loads, while self-lubricating bearings eliminate manual maintenance.
