1. Core Opening Section: Product Overview & Target Application
This specialized parts catalog is precision-engineered exclusively for Rolls-Royce MW 160 and MW 500 series anchor winches, covering specific model variants: Rolls-Royce MW 160E-S/CU1G3 (serial numbers 41470/41471, 41472/41473) and Rolls-Royce MW 500/52 E HWF 52 (serial numbers 39485, 39486 with roller assembly). Every component is manufactured to match original OEM dimensional tolerances, material specifications, and performance ratings, ensuring zero compatibility errors and direct fitment for these targeted anchor winch models.
2. Detailed Product & Technical Specifications
This portfolio features OEM-specified replacement components for Rolls-Royce MW 160 and MW 500 anchor winches, spanning critical wear parts, fasteners, bearings, sealing components, and lubrication fittings. All parts are fabricated from marine-grade, corrosion-resistant materials (including high-friction brake composites, hardened alloy steel, and saltwater-proof metals) to meet rigorous marine engineering standards. Each component is cross-referenced with original OEM part numbers (e.g., A6567340 brake lining, R6143407 rolling bearing) for accurate identification, covering all high-wear sections of the anchor winch: brake assemblies, chain drive systems, roller bearings, bushing sets, and lubrication points.
Functional Specifications
- Brake System Components: High-friction brake linings and heavy-duty brake rivets deliver stable, fade-resistant braking force for safe anchor lowering/hoisting, even under full-load marine conditions; rivets provide secure, vibration-proof bonding of brake linings to winch brakes.
- Load-Bearing & Rotating Parts: Precision-machined roller bearings and bushings reduce rotational friction, support heavy anchor chain loads, and prevent premature wear on winch shafts; hardened chain components withstand high-tension pulling forces without deformation.
- Sealing & Lubrication Parts: Durable roller seals block saltwater, debris, and contaminants from entering bearing assemblies; precision grease nipples enable reliable lubrication of critical winch components to extend service life.
- Structural Support Parts: Heavy-duty anvils and rugged rusk components reinforce winch structural integrity, absorbing impact loads during anchor handling operations.
Structural Characteristics
All components follow the modular design of Rolls-Royce MW 160 and MW 500 anchor winches, allowing for quick field replacement without full winch disassembly. Brake parts feature precision-cut profiles for perfect alignment with winch brake drums; bearings and bushings have tight tolerance fits (±0.002 inches) to eliminate radial play; lubrication nipples are engineered for easy access in confined marine engine room spaces. Every part is designed to mate seamlessly with existing winch hardware, cutting installation labor time and reducing repair complexity for onboard maintenance teams.
Applicable Operating Conditions
These replacement parts are rated for the extreme marine environments where Rolls-Royce MW 160 and MW 500 anchor winches operate, including:
- Saltwater exposure and high-humidity marine atmospheres (offshore vessels, drilling rigs, commercial ships)
- Continuous cyclic loading during anchor deployment, hoisting, and mooring operations
- Temperature range: -20°C (-4°F) to 60°C (140°F) for global marine voyages
- Heavy vibration and shock loads common in rough sea conditions

3. On-Site Fault Repair Case Studies
| Case 1: MW 160 Winch Brake Failure A commercial vessel’s Rolls-Royce MW 160 anchor winch experienced brake slippage during anchor hoisting, creating a safety hazard. Inspection revealed worn brake linings (A6567340) and sheared brake rivets (A6567335). Replacement of the brake lining set and full rivet replacement restored full braking friction, eliminating slippage and restoring safe winch operation within 2 hours of onboard repair.Case 2: MW 500 Winch Bearing Seizure An offshore drilling rig’s MW 500 anchor winch suffered a roller bearing seizure due to saltwater contamination. The failed rolling bearing (R6143407) and damaged roller seal (A6359428) were replaced, and the assembly was relubricated. This resolved the seizure issue, reduced rotational resistance, and prevented further damage to the winch shaft.Case 3: MW 160 Winch Lubrication Failure A vessel’s MW 160 winch developed excessive shaft noise caused by clogged grease nipples (A6648957). Replacing the clogged grease nipples and performing a full lubrication of bearing points eliminated noise and friction, extending the service life of rotating winch components by an estimated 2,000+ operating hours. |
4. Frequently Asked Questions (FAQ)
| FAQ Question | Detailed Answer |
| Are these parts compatible with all Rolls-Royce MW 160 and MW 500 winch variants? | These parts are specifically designed for the MW 160E-S/CU1G3 (SN 41470/41471, 41472/41473) and MW 500/52 E HWF 52 (SN 39485, 39486) models listed; cross-reference your winch serial number and OEM part number to confirm exact fitment. |
| What is the service life of brake linings for these anchor winches? | Under normal marine operating conditions, the OEM-spec brake linings last 1,500–2,500 operating hours, depending on anchor handling frequency and load conditions; regular inspections help extend service life. |
| Can I use generic marine bearings instead of the specified roller bearings? | Generic bearings lack the precision tolerance and corrosion resistance of these OEM-spec parts, leading to premature wear, winch damage, and safety risks; only the listed Rolls-Royce compatible bearings are recommended for reliable performance. |
