Introduction
This guide focuses on genuine parts for Bomco Rotary Table models ZP-175, ZP-205, ZP-275, ZP-375, ZP-375Z, ZP-495, and ZP-520C—critical components for oilfield drilling and workover rigs. These rotary tables are specifically engineered to integrate with Bomco rig models including ZJ series (ZJ50/3150D, ZJ70/4500D, ZJ90/6750D, etc.), XJ series (XJ900Z, XJ1350Z, etc.), and specialized units like GW-M1000 and ZJ50DBT.
Designed for harsh downhole and offshore environments, the parts (ranging from pawls, bearings, and gears to seal sets and fasteners) adhere to API (American Petroleum Institute) standards and Bomco’s strict manufacturing specifications. Target users include oilfield operation companies, rig maintenance teams, and aftermarket service providers who require reliable, drop-in replacement parts to minimize downtime, ensure operational safety, and maintain drilling efficiency.
A real-world maintenance case underscores the importance of genuine parts: A drilling team operating a ZJ50/3150DB rig experienced frequent rotary table jamming due to worn non-genuine left/right pawls (Parts 1 & 2). After replacing with authentic Bomco pawls, the issue was resolved, and the table’s service life extended by 18 months—avoiding costly rig downtime of approximately $20,000 per day. Another case involved a ZJ30/1700DB rig with oil leakage; replacing the O-seal rings (Parts 23, 29) and lower seal sets (Parts 22, 27) with genuine components restored sealing integrity, complying with environmental and operational regulations.

FAQs
Question | Answer |
How to confirm part compatibility with my Bomco rotary table and rig model? | Cross-verify the rotary table model (ZP series) and rig model (ZJ/XJ/GW series) with the provided part numbers (e.g., AG2050010803, AG27500100) and part names. Genuine Bomco parts are marked with unique part numbers that align with specific table and rig configurations. For ambiguous cases, provide the rig’s serial number and rotary table ID to ensure a precise match, avoiding non-compatible parts that risk equipment damage. |
What maintenance intervals are recommended for key rotary table parts? | Critical moving parts (bearings 38, 40, 58; pawls 1, 2; and seal sets 22, 27) require inspection every 500 operating hours. Bearings should be lubricated with API-certified grease, and seals replaced annually or at the first sign of leakage. Fasteners (bolts 24, 42; spring washers 41, 61) should be torque-checked quarterly to prevent loosening under high vibration—following Bomco’s torque specifications (e.g., M24×70 bolts torque to 450 N·m). |
Why choose genuine Bomco parts over aftermarket alternatives? | Genuine parts are manufactured to Bomco’s original design tolerances and material standards (e.g., forged steel for pawls, high-grade rubber for O-seals), ensuring compatibility and durability. Aftermarket parts often lack API compliance and may fail prematurely—leading to rig downtime, safety hazards (e.g., bearing failure causing table lockup), and voiding of equipment warranties. Genuine parts also retain the rotary table’s operational efficiency and resale value. |
