2. Functional Instructions
- Brake Linings (A6567340, A6567324, 5104351—01, A6567820): Provide friction to stop or hold the anchor windlass, ensuring safe anchor deployment and retrieval. The high-friction material ensures reliable braking even under heavy loads (up to 160 tons for MW 160E-S/CU1G3, 500 tons for MW 500/52 E HWF 52), with a service life of up to 2,000 operating hours.
- Brake Rivets (A6567335, A6568990, 6568984): Secure the brake linings to the brake drum, with high shear strength (≥600 MPa) to withstand the mechanical stress of braking. They are corrosion-resistant to prevent loosening in saltwater environments.
3. Structural Characteristics
All Rolls-Royce anchor spare parts are manufactured using high-quality, marine-grade materials to withstand the harsh offshore environment—characterized by saltwater, high humidity, extreme temperatures, and mechanical stress: Brake linings use a composite friction material (asbestos-free, compliant with EU RoHS standards) with a steel backing plate, ensuring high friction, heat resistance, and durability. Brake rivets and chains use high-strength carbon steel (SCM435) with hot-dip galvanization (zinc coating thickness ≥80 μm) for corrosion resistance, meeting ISO 1461 standards. Roller bearings use chrome steel (GCr15) with a hardened surface (HRC 60-64) and precision grinding, ensuring smooth operation and high load capacity. Roller bushings use phosphor bronze (CuSn10Pb1) for low friction and corrosion resistance in seawater. Grease nipples use stainless steel (304) to resist saltwater corrosion, with a brass valve core for reliable grease flow. Main gear wheels use 42 CrMo4V/42 CrMo4 alloy steel, heat-treated to HRC 28-32 for toughness and wear resistance. All parts undergo strict quality testing: brake linings undergo friction coefficient testing (≥0.45 at 200℃), chains undergo tensile strength testing (≥1,000 MPa), bearings undergo dimensional accuracy testing (ABEC-3 grade), and all metal parts undergo salt spray testing (≥1,000 hours) to ensure corrosion resistance. The defect detection rate is 100%, and the finished product qualification rate is 100%.

4. On-Site Fault Maintenance Cases
Case 1: MW 160E-S/CU1G3 Anchor Windlass Brake Failure Caused by Worn Brake Linings
Scenario: A Rolls-Royce MW 160E-S/CU1G3 anchor windlass (No. 41470) on an offshore drilling rig experienced reduced braking performance during anchor retrieval, with the anchor slipping under load. Inspection found that the A6567340 brake linings were worn to 3mm (below the 5mm minimum threshold), reducing friction and braking efficiency.
Solution: Replace the worn A6567340 brake linings with new OEM-compatible parts, using A6567335 brake rivets to secure them to the brake drum. After installation, test the braking performance to ensure it can hold the anchor load (160 tons) without slipping. The windlass resumed normal operation, eliminating the safety hazard and avoiding unplanned downtime.
Case 2: MW 500/52 E HWF 52 Windlass Roller Jamming Caused by Damaged Roller Bearing
Scenario: A Rolls-Royce MW 500/52 E HWF 52 anchor windlass (No. 39485) experienced roller jamming during operation, preventing anchor deployment. Inspection found that the 6143407 roller bearing R was corroded and seized due to saltwater ingress (damaged roller seal A), causing the roller to stop rotating.
Solution: Replace the damaged 6143407 roller bearing R and 6359428 roller seal A with new OEM-compatible parts, clean the roller assembly, and apply marine-grade lubricating grease. After maintenance, the roller rotated smoothly, and the windlass resumed normal anchor deployment and retrieval functionality.
Case 3: 3000 AGHC-KS-560 Gearbox Power Transmission Failure Caused by Worn Main Gear Wheel
Scenario: A Kamewa Ulstein Rolls-Royce 3000 AGHC-KS-560 main engine gearbox (inst.id.F11890) experienced power transmission failure, with the anchor windlass failing to receive power from the main engine. Inspection found that the 42 CrMo4V main gear wheel had excessive tooth wear (8% of original tooth thickness), causing gear slippage and power loss.
Solution: Replace the worn 42 CrMo4V main gear wheel with a new OEM-compatible part, align the gears to ensure proper meshing (ISO 5级 accuracy), and apply gear oil (ISO VG 320) to the gearbox. After maintenance, the gearbox resumed normal power transmission, and the anchor windlass operated as intended, avoiding costly gearbox replacement.
5. FAQ (Frequently Asked Questions)
| No. | Questions | Answers |
| 1 | Are these spare parts fully compatible with the specified Rolls-Royce equipment models (MW 160E-S/CU1G3, MW 500/52 E HWF 52, 3000 AGHC-KS-560, SL350W/BSL350W)? | Yes, all spare parts in this list are manufactured to meet or exceed Rolls-Royce OEM specifications, ensuring 100% compatibility with the specified equipment models and their respective serial numbers (e.g., MW 160E-S/CU1G3 Nos. 41470/41471, 41472/41473). Each part matches the original dimensions, material specifications, and performance parameters, ensuring seamless installation and stable operation. We strictly follow API 8C, ISO 6406, and ISO 9001 standards, eliminating the risk of mismatched parts and equipment failure. |
| 2 | What is the difference between the A6567340 and A6567324 brake linings, and how to choose the right one for my Rolls-Royce anchor windlass? | The key difference is their compatibility with specific windlass models: the A6567340 brake lining is designed for Rolls-Royce MW 160E-S/CU1G3 anchor windlasses (Nos. 41470/41471, 41472/41473), while the A6567324 is an alternative brake lining for the same MW 160E-S/CU1G3 model. Both have the same friction coefficient (≥0.45) and load capacity (160 tons), so they are interchangeable for the MW 160E-S/CU1G3. For the MW 500/52 E HWF 52 windlass, use the 5104351—01 or A6567820 brake linings. Always refer to the equipment’s serial number and maintenance manual to confirm the correct part number. |
| 3 | How to quickly confirm the correct part number when purchasing Rolls-Royce anchor spare parts for emergency offshore maintenance? | You can use three simple methods to confirm: 1) Check the original Rolls-Royce equipment maintenance manual, which lists the part number for each component corresponding to the equipment model and serial number; 2) Remove the faulty part and check the part number marked on its surface (all OEM-compatible parts have clear, permanent marking); 3) Provide the Rolls-Royce equipment model, serial number, and the faulty component’s description (e.g., brake lining, roller bearing, main gear wheel) to our technical team, and we will accurately match the corresponding part number. This list covers 26 common spare parts, meeting most emergency maintenance needs for offshore drilling operations. |
