API Rotary Tables
Because the ZP series features heavy-duty thrust bearings and precision-machined gears rated for 1,000-ton static loads, OUSUN rotary tables deliver consistent torque transmission across ZJ30 to ZJ90 rigs, eliminating mechanical slippage during deep-well drilling. Because these API 7K-certified units offer 17.5" to 49.5" openings with interchangeable mounting footprints, installation integrates directly into existing OEM rig designs, cutting rig-up downtime by an average of 48 hours.
