Product Introduction
This comprehensive spare parts catalog features direct-fit OEM replacement components for routine preventive maintenance, partial repairs, and full overhauls of Rolls-Royce MW 160E-S and MW 500/52 E HWF 52 anchor winches, covering all high-wear, safety-critical parts: brake linings, brake rivets, anchor chains, roller bearings, roller bushings, shaft seals, and grease nipples. Unlike generic marine aftermarket parts, each component is built to the original Rolls-Royce anchor winch design specifications, marine-grade material standards, and dimensional tolerances, ensuring seamless on-vessel installation, zero compatibility errors, and reliable performance under the extreme conditions of saltwater marine operations. The collection is curated to cover all safety-critical winch parts needed to keep anchoring and mooring operations compliant, safe, and efficient.
Functional Specifications
- Brake System Components: High-friction OEM brake linings deliver consistent, reliable stopping power for heavy anchor loads; precision-hardened brake rivets secure linings firmly to winch brake shoes, preventing slippage and ensuring compliance with maritime braking safety standards.
- Roller & Bearing Assemblies: Heavy-duty roller bearings reduce friction in winch rotating shafts; precision-machined roller bushings align moving components, while waterproof roller seals block saltwater and debris to prevent corrosion and premature bearing failure.
- Lubrication Fittings: Marine-grade grease nipples enable reliable, leak-free lubrication of winch bearings and bushings; multiple fitting sizes accommodate all lubrication points on both MW series winch models, simplifying routine maintenance.
- Structural & Connecting Parts: Heavy-duty anchor chains withstand extreme anchoring tension; custom seals and bushings protect internal winch components from saltwater damage, preserving long-term operational integrity.
Structural Characteristics
All Rolls-Royce MW anchor winch spare parts feature rugged, marine-specific construction for maximum durability: brake linings use heat-resistant, high-friction composite materials designed for heavy-duty marine braking; rivets and structural parts use corrosion-resistant hardened steel to withstand saltwater oxidation; bearings and bushings use precision-ground surfaces for low-friction rotation; seals use saltwater-resistant elastomers to maintain waterproof integrity. Components are designed for tool-friendly on-vessel installation, minimizing repair time during port calls and reducing vessel downtime costs.
Applicable Operating Conditions
These spare parts are engineered to perform reliably in the harsh marine conditions of Rolls-Royce MW anchor winch operation, including:
- Continuous heavy-load anchoring and mooring for commercial vessels and offshore marine assets
- Prolonged exposure to saltwater, high humidity, and marine corrosion
- Extreme cyclic vibration from winch operation and vessel movement
- Ambient temperatures ranging from -10°C (14°F) to 55°C (131°F) across global maritime routes
- Full compliance with IMO, DNV GL, and international marine equipment safety standards
Maintenance & Servicing Recommendations
- Pre-Installation Verification: Cross-reference OEM part numbers against Rolls-Royce MW winch technical manuals to confirm exact fit for MW 160E-S or MW 500/52 E HWF 52 models; inspect parts for corrosion or defects and clean all mating surfaces to remove salt deposits and debris before assembly.
- rake linings for wear and rivets for looseness every 1,200 operating hours; replace worn brake linings and damag
- Bearing & Seal Care: Lubricate roller bearings and bushings via grease nipples every 600 operating hours; replace worn roller seals promptly to prevent saltwater intrusion; inspect bearings for roughness or play and replace at the first sign of wear.
- Lubrication Fitting Checks: Clear clogged grease nipples quarterly and replace faulty fittings immediately to ensure consistent lubrication; use marine-grade grease approved for Rolls-Royce winch components to prevent corrosion.
- Structural Component Inspection: Check anchor chains for wear and deformation every 1,800 hours; inspect bushings for alignment and wear, replacing damaged parts to preserve winch shaft integrity.

On-Vessel Anchor Winch Fault Repair Cases
Case 1: Brake Slippage & Anchoring Safety Hazard
A vessel’s Rolls-Royce MW 160E-S anchor winch experienced dangerous brake slippage during anchoring, caused by heavily worn brake linings (A6567340) and loose, degraded brake rivets. The compromised brake system failed to hold anchor load, risking vessel drift and non-compliance with maritime safety rules. Replacing the worn brake linings and installing new OEM rivets restored full braking capacity and safe anchoring operation.
Case 2: Roller Bearing Failure & Winch Jamming
A Rolls-Royce MW 500/52 E HWF 52 anchor winch suffered a seized roller bearing (6143407) due to a faulty grease nipple that blocked lubrication, leading to dry rotation and component wear. The bearing seizure jammed the winch, halting mooring operations during a port call. Replacing the clogged grease nipple and failed roller bearing, then lubricating the assembly, restored smooth winch rotation.
Case 3: Seal Leak & Component Corrosion
Saltwater intrusion through a damaged roller seal (6359428) on a MW 500/52 E HWF 52 winch caused corrosion of roller bushings and premature wear of internal components. The corrosion increased friction and reduced winch efficiency. Installing a new OEM roller seal, cleaning corroded bushings, and replacing damaged parts prevented further saltwater damage and restored winch performance.
