Product Introduction
This curated selection of Jiangsu Rushi power tong spare parts covers all high-wear and critical components for the JML2-F0.8H unit, including oil engines, transfer/clamp cylinders, gripping jaws, gear assemblies, bearings, hydraulic valves, seals, fasteners, and pressure gauges. Every part is manufactured to meet national mechanical standards (GB/JB/ZQ series) and oilfield equipment durability benchmarks, with strict quality inspection to withstand cyclic loading, high hydraulic pressure, and harsh rig site conditions. Each part is traceable to its original Rushi part number, simplifying inventory stocking and repair workflow for field teams.
Functional Performance Specifications
These spare parts are engineered to preserve the full operating performance of the Jiangsu Rushi JML2-F0.8H power tong: stable hydraulic pressure regulation up to 20MPa, consistent tubular gripping force to prevent slippage, smooth gear shifting for torque transmission, and leak-free hydraulic/pneumatic system operation. Cylinder components deliver precise linear actuation; jaw and die inserts provide non-damaging tubular grip; bearings and gears reduce friction loss by up to 30%; and seal kits eliminate fluid leakage to maintain system pressure efficiency.
Structural & Material Features
- OEM-Certified Fitment: Precision-machined to match JML2-F0.8H original dimensions, requiring no on-site modification or reworking for installation
- Heavy-Duty Material Construction: Forged alloy steel for load-bearing cylinders and gears, wear-resistant carbide for jaw dies, and oil-resistant nitrile rubber for hydraulic seals
- Standardized Compliance: Bearings, fasteners, and seals meet GB283-64, GB70-87, JB/ZQ4224-97, and other national mechanical standards for reliability
- Modular Repair Design: Pre-sized seal kits, jaw inserts, and bearing sets cut field repair time by nearly 50% compared to custom-made parts
- Wear-Resistant Surface Treatment: Heat-treated gear teeth and jaw surfaces extend component service life by 40% under heavy cyclic use
Applicable Operating Conditions
These Jiangsu Rushi power tong spares are built for onshore oilfield well servicing and drilling environments, including tubing/casing makeup/breakout, sucker rod handling, and workover operations. They perform reliably in ambient temperatures ranging from -15℃ to 55℃, high-dust rig sites, high-vibration conditions, and exposure to hydraulic oil, drilling mud, and mild corrosive well fluids. Components are rated for continuous heavy-duty operation and frequent torque cycling typical of power tong use.
Maintenance & Upkeep Recommendations
- Inspect jaw dies, clamp cylinders, and breaker bands every 80 tubular handling cycles to replace worn parts before failure
- Lubricate bearings, gear assemblies, and cylinder rods monthly with high-grade lithium grease to reduce friction and prevent corrosion
- Check hydraulic seals, O-rings, and valve components quarterly to fix leaks and maintain consistent system pressure
- Tighten fasteners (GB70-87 bolts) biweekly to prevent loosening from rig vibration and ensure structural stability
- Calibrate pressure gauges (YK-100) every 6 months to ensure accurate pressure monitoring and safe operation

Field Failure Repair Case Studies
Case 1: JML2-F0.8H Clamp Cylinder Failure
A drilling rig experienced loss of gripping force on the Jiangsu Rushi JML2-F0.8H power tong due to a worn clamp cylinder (P/N 01.04.00M). Replacing the faulty cylinder with an OEM spare restored full clamping pressure, eliminated tubular slippage, and resumed tubing running operations without further delays.
Case 2: Worn Jaw Inserts Causing Tubular Damage
A well servicing team noticed surface scratching on tubing due to degraded Rushi jaw inserts (P/N 01.01-15M/16M/17M). Installing new jaw inserts restored a secure, non-damaging grip, preventing tubing waste and bringing the power tong back to compliance with field handling standards.
Case 3: Hydraulic Seal Leakage in Transfer Cylinder
A JML2-F0.8H power tong lost hydraulic pressure from leaking YX seal rings (JB/ZQ4264-97) in the transfer cylinder (P/N 02.00M). Replacing the worn seals with genuine Rushi spare seals stopped fluid leakage, restored system pressure, and avoided a full cylinder replacement.
