Product Description
This comprehensive collection features direct-fit OEM replacement parts for Rolls-Royce MW series anchor winches, eliminating compatibility errors and restoring factory-level marine performance. The lineup includes high-friction brake linings, corrosion-resistant brake rivets, heavy-duty anchor chains, precision roller bearings, marine-grade roller bushings, sealing components, and lubrication nipples. Unlike generic marine aftermarket parts, these components are forged and machined to Rolls-Royce’s original marine-grade specifications, calibrated for the winches’ rated anchoring load capacity and saltwater operating conditions, ensuring seamless installation and consistent performance in offshore and coastal marine environments.
Functional Specifications
- Brake System Components: A6567340 and 5104351—01 brake linings deliver stable static friction force (≥0.45 friction coefficient) to secure heavy anchor loads; high-shear brake rivets (A6567335, 6568984) lock brake linings firmly in place under heavy braking loads, preventing detachment during anchor operations.
- Transmission & Bearing Parts: Precision roller bearings (6141515, 6143407) reduce rotational friction by 40% and support radial loads up to 150kN; hardened roller bushings extend winch roller service life and resist saltwater wear; marine-grade roller seals block moisture and debris to prevent bearing corrosion.
- Lubrication & Auxiliary Parts: Corrosion-resistant grease nipples (6648104, 6648105) enable hassle-free lubrication of moving components; heavy-duty anchor chains (A6490219) provide reliable load transfer for anchor deployment and retrieval.
Structural Characteristics
All Rolls-Royce anchor winch parts feature rugged, marine-specific construction for maximum durability: brake linings use high-temperature, salt-resistant friction composites to avoid brake fade under heavy loads; bearings and bushings use 316 stainless steel and hardened alloy steel with anti-corrosion coating; brake rivets are forged for high shear strength to withstand cyclic braking forces; lubrication nipples feature sealed caps to prevent saltwater intrusion and clogging. Components are designed for tool-friendly on-vessel installation, with standardized mounting interfaces to cut repair time during critical marine operations.
Applicable Operating Conditions
These spare parts are engineered for the extreme marine environments of commercial vessels, offshore rigs, and coastal ships, including:
- Offshore and coastal marine vessel anchoring operations with heavy anchor loads
- Saltwater, high-humidity, and corrosive marine environments
- Ambient temperatures from -10°C (arctic marine operations) to 55°C (tropical offshore zones)
- Continuous anchor winch cycling for deployment, retrieval, and stationary load holding
- DNV GL and Lloyd’s Register certified marine machinery systems
Maintenance & Servicing Recommendations
- Pre-Installation Inspection: Verify Rolls-Royce OEM part numbers against winch technical drawings; clean mounting surfaces to remove salt deposits and debris; inspect brake linings for wear and bearings for corrosion before installation.
- Brake System Maintenance: Inspect brake lining thickness every 3,000 operating hours; replace linings when thickness drops below 3mm; torque brake rivets to specified values to ensure secure fastening; test brake holding capacity under full anchor load post-repair.
- Bearing & Bushing Care: Lubricate roller bearings and bushings quarterly with marine-grade grease; inspect seals for damage every 5,000 hours; replace worn bearings and bushings to eliminate abnormal noise and friction.
- Lubrication System Upkeep: Clear clogged grease nipples with compressed air; replace damaged nipples immediately to maintain proper lubrication flow; use only marine-grade, corrosion-inhibiting lubricant for winch components.
- Post-Installation Testing: Conduct full anchor deployment and retrieval cycles to test functionality; check for brake slippage and abnormal noise; inspect for lubrication leaks and saltwater intrusion after testing.

On-Vessel Anchor Winch Fault Repair Cases
Case 1: MW 160E-S/CU1G3 Winch Brake Fade & Anchor Slippage
A commercial vessel’s Rolls-Royce MW 160E-S/CU1G3 anchor winch experienced dangerous anchor slippage during stationary mooring, caused by heavily worn A6567340 brake linings and loose brake rivets. The degraded linings lost friction capacity, failing to hold the anchor load securely. Replacing the worn brake linings and installing new high-shear rivets restored full brake holding power and eliminated slippage.
Case 2: MW 500/52 E HWF 52 Winch Bearing Seizure
An offshore rig’s Rolls-Royce MW 500/52 E HWF 52 anchor winch developed rough rotation and abnormal noise, traced to a seized 6143407 roller bearing due to saltwater contamination and lack of lubrication. The seized bearing disrupted chain deployment and created a safety hazard. Replacing the faulty bearing, damaged roller seal, and clogged grease nipple restored smooth winch operation.
Case 3: MW 500/52 E HWF 52 Winch Lubrication Leak
A coastal ship’s MW 500/52 E HWF 52 anchor winch had persistent lubrication leaks around the roller assembly, caused by a cracked 6359428 roller seal and worn roller bushings. The leak depleted lubricant and exposed components to saltwater corrosion. Installing a new seal and replacement bushings, plus replacing damaged grease nipples, stopped leaks and protected components from corrosion.
