Introduction
The BJ5350 lifting hook parts are precision-engineered components designed exclusively for the BJ5350 lifting hook system, a critical asset in drilling, construction, and heavy-industry operations. These parts are crafted to meet the rigorous demands of high-load lifting, frequent swiveling, and extreme working conditions, ensuring optimal performance, safety, and longevity of your lifting equipment. Whether you’re replacing worn components, conducting routine maintenance, or addressing unexpected breakdowns, our comprehensive parts list delivers the exact-fit solutions you need to minimize downtime and maximize operational efficiency.
Core Purpose
Designed to support the BJ5350 lifting hook’s core functions—load-bearing, swiveling, locking, and shock absorption—these parts work in synergy to ensure secure and reliable lifting of heavy materials (up to 50+ tons, depending on configuration) in drilling sites, construction yards, and industrial facilities. Each component, from main bearing assemblies to snap rings, is manufactured to strict industry standards (ISO 9001 certified, ASME B30.20 compliant) to maintain the hook’s structural integrity, prevent load slippage, and withstand repeated use in harsh environments.
Key Features
1. Precision Engineering & Durability
All BJ5350 lifting hook parts are machined from high-grade materials (e.g., heat-treated alloy steel for pins and shanks, industrial-grade rubber for O-rings/quad rings) to resist corrosion, wear, and impact. Critical components like the Main Bearing Assembly (Part Nos. 26025, 12811) and Swivel Ring (27006) feature precision tolerances (±0.02mm) to ensure smooth swiveling and consistent load distribution, reducing friction-related damage by 30% compared to generic alternatives.
2. Safety-Centric Design
Safety is paramount in lifting operations, and these parts are engineered to eliminate common failure points. The Positioner Lock Assembly (27009, 24441-1) and Lower Locking Arm Pin Assembly (26021-1, 24823-1) incorporate redundant locking mechanisms to prevent accidental disengagement, while the Main Relief Spring (26037, 12799) regulates pressure to avoid overloading, complying with OSHA 1926.251 safety standards.
3. Modular & Interchangeable Structure
The parts follow a modular design, allowing easy interchangeability and compatibility with the BJ5350 system. Standardized part numbers (e.g., Grease Fitting 940308-1, Snap Ring 944408-825) ensure quick identification and replacement, while common components (such as Quad Rings 946998-36 and Back-Up Rings 942183-36) reduce inventory complexity for maintenance teams.
4. Optimized for Heavy-Duty Performance
Components like the Cam Roller Ring (26958, 945030-15) and Cam Follower (19609) are designed to handle high rotational speeds (up to 150 RPM) and radial loads, making them ideal for continuous lifting cycles. The Snubber Housing (30552, 30560) and Piston (30547, 30558) provide shock absorption, reducing load impact by 40% and extending the hook’s service life by 25%.
Application Conditions
The BJ5350 lifting hook parts are tailored for use in:
- Onshore and offshore drilling rigs (supporting drill pipe lifting and casing operations)
- Construction sites (hoisting steel beams, concrete blocks, and heavy machinery)
- Industrial manufacturing facilities (moving large equipment and raw materials)
- Mining operations (lifting ore containers and excavation tools)
- They perform reliably in temperatures ranging from -20°C to 60°C, and can withstand high humidity, dust, and minor chemical exposure—common in harsh worksites.
Maintenance & Care Recommendations
To ensure peak performance and longevity of your BJ5350 lifting hook parts:
- Regular Lubrication: Use the specified Grease Fitting (940308-1) to apply high-temperature grease every 50 operating hours, focusing on main bearings, swivel rings, and cam rollers.
- Inspection Schedule: Check locking components (e.g., Latch 12103, Positioner Lock Assembly) weekly for signs of wear, deformation, or corrosion. Replace parts if wear exceeds 0.5mm or if O-rings/quad rings show cracks.
- Torque Verification: Ensure Bail Bolts (16705) and Clevis Pins (939502-48) are tightened to the manufacturer’s recommended torque (250-300 N·m) to prevent loosening during operation.
- Storage Guidelines: Store spare parts in a dry, temperature-controlled environment (10-25°C) to avoid rust. Seal rubber components (O-rings, quad rings) in airtight containers to prevent degradation.

Field Fault Repair Cases
Case 1: Swivel Ring Seizure
Issue: A drilling team experienced swivel ring seizure during pipe lifting, causing operational downtime.
Root Cause: Lack of lubrication led to friction-induced damage to the Swivel Ring (27006) and Main Bearing Assembly (26025).
Solution: Replaced the worn swivel ring and bearings with BJ5350-compatible parts, followed by lubrication using the specified grease fitting. The system resumed normal operation within 2 hours, and regular lubrication prevented recurrence.
Case 2: Locking Mechanism Failure
Issue: A construction company’s lifting hook failed to lock securely, posing a safety risk.
Root Cause: The Positioner Lock Assembly (24441-1) was worn, and the Cotter Pin (939667-28) was bent.
Solution: Installed a new positioner lock assembly and cotter pins from the BJ5350 parts list. Post-repair testing confirmed the locking mechanism’s reliability, complying with safety standards.
Case 3: Oil Leakage from Snubber Housing
Issue: Oil leakage was detected from the Snubber Housing (30552) during heavy-load lifting.
Root Cause: Deteriorated O-ring (942271-71) and Back-Up Ring (942183-36) failed to seal properly.
Solution: Replaced the worn seals with BJ5350-specific O-rings and back-up rings. Leakage was eliminated, and the snubber’s shock absorption function was restored.
