Product Introduction
This comprehensive SL 225 swivel spare parts kit includes direct-fit OEM replacement components for routine preventive maintenance, emergency breakdown repairs, and full swivel system overhauls. The collection covers upper/lower bushings, main bearings, packing assemblies, O-rings, grease fittings, specialized studs/nuts, oil seals, and wash pipes—all designed to eliminate compatibility issues and streamline on-rig installation. Unlike generic aftermarket parts, each component is manufactured to the exact design specifications of the SL 225 drilling swivel, ensuring reliable performance under high-pressure mud circulation and heavy drilling loads, while adhering to API 8C industry standards for drilling hoisting equipment.
Functional Specifications
- Sealing & Packing Components: High-density packing sets (104.05.30.08) and O-rings prevent high-pressure mud leakage; oil seals (07-1-67) lock lubrication inside the bearing cavity; gaskets create tight flange seals to block mud and debris intrusion.
- Bearing & Bushing Components: Main bearings (9019456, 32240, 2007140) support smooth swivel rotation and absorb axial/radial loads; upper/lower bushings reduce friction between moving parts and extend component lifespan.
- Fastening & Hardware Components: Precision studs, nuts, and spring washers (GB standard series) maintain tight assembly under constant drilling vibration; snap rings and retaining rings secure internal components in place.
- Lubrication & Auxiliary Components: Grease fittings enable timely lubrication of critical moving parts; oil gages monitor lubricant levels; wash pipes facilitate smooth mud circulation without blockages.
Structural Characteristics
All SL 225 swivel spare parts feature rugged, drilling-specific construction for maximum durability: sealing components use oil and mud-resistant NBR rubber to resist degradation; bearings use high-carbon chrome alloy steel for heavy-load capacity and anti-friction performance; bushings use wear-resistant cast iron for long-term stability; fasteners use high-tensile steel with anti-corrosion coating to withstand harsh drilling environments. Parts are designed for tool-friendly field installation, with precise dimensional matching to OEM specifications for hassle-free replacement during critical drilling operations.
Applicable Operating Conditions
These spare parts are engineered to perform reliably in demanding drilling environments, perfectly suited for:
- Full operation of SL 225 drilling swivel in onshore drilling and offshore workover rigs
- High-pressure mud circulation up to 35MPa and rotational speeds up to 300r/min
- Continuous heavy-load hoisting and rotary drilling operations
- Harsh environments with mud exposure, vibration, and temperature fluctuations (-20°F to 220°F)
- Compliance with API 8C and GB standard drilling equipment specifications
Maintenance & Servicing Recommendations
- Pre-Installation Verification: Cross-reference OEM part numbers against SL 225 swivel technical manuals to confirm exact fitment; inspect parts for defects and clean mating surfaces to remove mud, grease, and debris before assembly.
- Seal & Packing Replacement Schedule: Replace packing sets, O-rings, and oil seals every 1,500 drilling hours; inspect for cracks, hardening, or leakage monthly and replace immediately to prevent mud intrusion.
- Bearing & Bushing Care: Lubricate main bearings and bushings via grease fittings every 500 drilling hours; inspect bearings for noise or play every 1,000 hours and replace at the first sign of wear to avoid swivel failure.
- Fastener Inspection: Retorque studs, nuts, and bolts to OEM torque specifications after every major repair; replace worn spring washers and snap rings to maintain assembly tightness under vibration.
- Routine Checks: Monitor oil levels via oil gage weekly; inspect wash pipes for blockages and damage; clean grease fittings regularly to ensure unobstructed lubrication flow.

On-Rig Fault Repair Cases for SL 225 Swivel
Case 1: SL 225 Swivel Mud Leakage from Worn Packing
An SL 225 drilling swivel experienced severe high-pressure mud leakage at the packing assembly, caused by degraded packing sets (104.05.30.08) and worn O-rings. The leakage disrupted mud circulation and risked bearing damage. Replacing the packing set and O-rings eliminated leakage and restored proper sealing performance.
Case 2: Main Bearing Failure Causing Rotational Noise
The SL 225 swivel developed loud rotational noise and uneven rotation, traced to a worn main bearing (9019456) due to insufficient lubrication. The issue halted drilling operations and risked further swivel damage. Installing a new main bearing and performing full lubrication restored smooth, quiet swivel rotation.
Case 3: Loose Fasteners Causing Swivel Instability
During drilling operations, the SL 225 swivel showed excessive movement and instability, caused by loose studs (GB898-88 M24X65) and worn spring washers from constant vibration. Tightening fasteners and replacing worn washers restored swivel stability and prevented potential assembly failure.
