Marine Crane JC0000-5325R0-6101 160/230 UPP Hydraulic Cylinder ASS'Y Φ250 Right Bolt Seal Kit-Leak-Proof Ship Repair Parts

This professional repair seal kit is specially designed for Marine Crane JC0000‑5325R0‑6101 160/230 UPP Hydraulic Cylinder ASS'Y Φ250 Right Bolt. Engineered for harsh offshore and marine working environments, this complete overhaul kit includes all required sealing components for refurbishing the right‑hand bolt‑type upper hydraulic cylinder of Oriental marine crane. It restores cylinder sealing performance, prevents internal & external oil leakage, and guarantees stable lifting & luffing operation of shipboard crane under heavy‑load sea conditions.

1. Exact OEM‑Matching Compatibility Custom‑tailored for JC0000‑5325R0‑6101 160/230 Φ250 Right Bolt Upper Hydraulic Cylinder. Every seal dimension strictly follows original drawing specification, achieving perfect fit for piston and rod assembly, eliminating oil bypass and pressure loss.
2. Full Complete Overhaul Kit Comprises full set of rod seals, piston seals, buffer rings, wear rings, backup rings, dust wipers and O‑rings. No extra spare parts needed for full cylinder rebuild. All sealing elements are sorted and marked for easy identification during workshop overhaul.
3. Premium Marine‑Grade Sealing Materials Adopt high‑performance anti‑aging elastomer compound, resistant to salt‑water corrosion, seawater splash, hydraulic oil erosion, heavy shock load and wide temperature fluctuation. Long service life under continuous marine deck operation.
4. High Pressure & Heavy‑Duty Resistance Optimized for marine crane luffing cylinder high‑pressure working conditions. Effectively withstand frequent pressure surges caused by wave impact and variable cargo loads, minimizing leakage risk under dynamic marine operating circumstances.
5. Anti‑Extrusion & Wear‑Resistant Performance Equipped with high‑strength backup rings and wear rings to prevent seal extrusion under peak pressure. Reduce friction wear on cylinder rod surface, extend service cycle between two maintenance intervals.
6. Cost‑Effective Ship Repair Solution Ready‑to‑use complete kit, shorten vessel onboard repair downtime. Avoid time‑consuming separate sourcing of scattered seals, ideal for ship chandler, shipyard and vessel self‑maintenance.

Application: Specially applied to Oriental Marine Crane JC0000‑5325R0‑6101 160/230 UPP Hydraulic Cylinder ASS'Y Φ250 Right Bolt. Widely used for shipboard crane luffing / lifting hydraulic cylinder overhaul repair for bulk carrier, general cargo ship and offshore working vessel.

Installation Notice:

1. Ensure the hydraulic system is completely depressurized and power is disconnected before maintenance.
2. Clean all cylinder components thoroughly and inspect piston rod surface for scoring, pitting or wear before installing new seals. Damaged rod surface will shorten seal lifespan sharply.
3. Lubricate all sealing elements with clean compatible hydraulic oil during assembly to avoid seal cutting and twisting damage.
4. Check backup rings and buffer ring installation direction strictly according to cylinder drawing; reversed installation will lead to early seal failure.
5. After assembly, perform low‑pressure trial run before putting crane into full‑load working status.

For various types of reducer gearboxes, bearing boxes, thread seals, mechanical seals and other equipment sealing parts, long‑term high‑torque mechanical movement can cause the gearbox meshing gap to become larger, resulting in increased noise and equipment vibration. Additionally, sealing parts operating at high speed and temperature for extended periods may experience oil leakage due to:

• Leakage caused by oil seal quality problems
• Improper lubrication management resulting in excessive oil addition or lack of oil causing dry grinding
• Damage to seals during maintenance processes causing seal failure
• Blocked oil level vent leading to excessive internal pressure

These issues not only affect the safe and continuous operation of production equipment but also cause significant cost consumption and environmental oil pollution risk.

Note: We accept mixed large‑quantity orders, each oil seal kit can be wholesaled in bulk. We also accept small‑batch trial orders of various types of seal kits. Reliable quality with preferential price available.
