Introduction: Why Quality Anchor Winch Parts Are Non-Negotiable for Drilling Site Safety & Efficiency
If you’re an on-site drilling engineer, you know the nightmare of an anchor winch breakdown: a worn brake lining (like A6567340 or A6567820) fails to hold under heavy load, a faulty roller bearing (A6141515, R6143407) seizes up mid-operation, or a stripped brake rivet (A6567335, R6568984) causes a critical component to come loose. On offshore or onshore drilling sites, anchor winches aren’t just equipment—they’re the safety backbone, keeping rigs stabilized and operations on track. A single subpar part can lead to costly downtime (we’re talking $10,000+ per hour), safety hazards for your team, and missed project deadlines. Designed specifically for Rolls-Royce MW 160 (MW 160E-S/CU1G3, No. 41470/41471, 41472/41473) and MW 500 (MW 500/52 E HWF 52, No. 39485, 39486) anchor winches, our full range of replacement parts—from brake linings and rivets to roller bearings, grease nipples, and chains—are engineered to match the exact specifications of your equipment, ensuring seamless compatibility and uncompromising performance in the harshest drilling conditions.
Product Overview

We focus on the high-wear, high-stress components that are most prone to failure in drilling operations: brake linings (A6567340, A6567324, A6567820), brake rivets (A6567335, A6568990, R6568984, R6567335), roller bearings (A6141515, R6143407, R6347400), grease nipples (A6648957, A6648104, R6648103, R6648104, R6648105), chains (A6490219), anvils (E54212450-0-000), rusk (5200017—01), rolls bushings (ALA5406855—01, ALA5406856—01, ALA5406859—01), and roller seals (A6359428). Every part is manufactured to meet or exceed the original equipment standards for Rolls-Royce MW 160 and MW 500 anchor winches, ensuring they fit perfectly, perform reliably, and extend the service life of your winch. Whether you’re replacing a single grease nipple or stocking up on brake rivets for scheduled maintenance, these parts are built to keep your anchor winch running smoothly, even in the most demanding drilling environments.
Function & Structural Features
Each component is engineered with a clear focus on its core function in anchor winch operation: Brake linings (A6567340, A6567820) deliver consistent stopping power, with a non-asbestos, resin-impregnated friction material that resists heat buildup and wear—critical for safely securing heavy anchors under load. Brake rivets (A6567335, R6568984) securely fasten brake linings to the winch drum, featuring a heat-treated steel construction that resists shearing and stripping. Roller bearings (A6141515, R6347400) reduce friction in the winch’s rotating components, with a sealed design that prevents dirt, water, and drilling debris from entering, ensuring smooth operation. Grease nipples (A6648104, R6648105) provide easy lubrication access, with a corrosion-resistant finish that stands up to saltwater and harsh drilling chemicals. Structurally, all parts feature tight dimensional tolerances—within ±0.0015 inches for bearings and rivets—to ensure perfect fit with Rolls-Royce MW 160 and MW 500 winch housings, drums, and mounting points. This precision eliminates the risk of misalignment, which is a top cause of premature part failure and winch breakdowns.
Applicable Working Conditions
These Rolls-Royce anchor winch parts are built to thrive in both onshore and offshore drilling environments—some of the harshest conditions on the planet. They perform reliably in operating temperatures ranging from -30°F to 250°F (-34°C to 121°C)—critical for winches exposed to direct sunlight (onshore) or frigid offshore winds. The parts can withstand continuous loads up to 120,000 lbs (54,431 kg) for MW 500 winches and 80,000 lbs (36,287 kg) for MW 160 winches, meeting the anchor winch’s rated load requirements. Designed to resist corrosion from saltwater (offshore), drilling fluids, and harsh chemicals (onshore), the components meet EExd certification for use in explosive hazardous areas (Zone 1 and 2), ensuring compliance with drilling site safety standards. Whether your winch is operating on a desert onshore rig with high dust and temperature fluctuations or an offshore platform with salt spray and constant vibration, these parts maintain their integrity and performance, reducing the need for frequent replacements and unplanned downtime.
On-Site Maintenance Tips for Engineers
As an on-site engineer, you know that proper maintenance is key to extending the life of your anchor winch parts—and your winch. Here are practical, field-tested tips we’ve gathered from working with drilling teams around the world: First, inspect brake linings (A6567340, A6567820) every 2,000 operating hours—replace them if the friction material is worn to less than 3mm thick (the minimum safe thickness for reliable stopping power). For brake rivets (A6567335, R6568984), torque them to 28 ft-lbs (38 N·m) during installation to avoid under-tightening (which causes linings to shift) or over-tightening (which strips threads). Roller bearings (A6141515, R6143407) should be lubricated every 1,500 hours with high-temperature, water-resistant grease—use the grease nipples (A6648104, R6648103) to ensure full lubrication, and check for signs of seizing (unusual noise, increased friction) during each inspection. Grease nipples themselves should be cleaned regularly to prevent clogs from dirt and debris—if a nipple is clogged, replace it immediately to avoid bearing damage. Finally, keep a stock of critical parts (brake linings, rivets, and grease nipples) on-site—this cuts down on downtime when a component fails unexpectedly, especially on offshore rigs where resupply can take days.
Test Data & Certification Compliance
We don’t just claim our Rolls-Royce anchor winch parts are reliable—we back it up with real, non-percentage实测 data and industry certifications. Our brake linings (A6567340, A6567820) have a friction coefficient of 0.35–0.65 at 150°C and a wear rate of ≤1.0 x 10⁻⁷ cm³/N·m, with a fatigue life of 80,000 operating cycles under full load—far exceeding the Rolls-Royce standard requirement of 50,000 cycles. Brake rivets (A6567335, R6568984) are made from high-carbon steel with a Rockwell hardness of HRC 38–42, ensuring they resist shearing under loads up to 15,000 lbs (6,804 kg). Roller bearings (A6141515, R6347400) feature a chrome steel construction with a hardness of HRC 60–65, a load capacity of 25,000 lbs (11,340 kg), and a service life of 12,000 operating hours under continuous use. All parts are manufactured in compliance with ASME B18.3 (for rivets and fasteners), MSDS standards for material safety, and EExd and UL certifications for hazardous area use. Each batch undergoes rigorous testing—including load testing (150% of rated load for 2 hours), corrosion testing (72-hour salt spray), and dimensional inspection—to ensure consistency. Our material certification is fully traceable, so you can verify the origin and quality of every part you receive.

Procurement & On-Site Failure Standards
Procurement Selection Standards: When selecting parts for your Rolls-Royce MW 160 or MW 500 anchor winch, prioritize four key factors to avoid costly mistakes: 1) Dimensional Accuracy: Ensure parts match Rolls-Royce’s original specifications (e.g., brake lining thickness, bearing inner diameter) within ±0.0015 inches to avoid misalignment. 2) Material Quality: Choose non-asbestos friction material for brake linings (resists heat and wear), high-carbon steel for rivets (resists shearing), and chrome steel for bearings (resists corrosion and friction). 3) Certification: Verify compliance with ASME B18.3, EExd, and UL standards—critical for hazardous drilling environments. 4) Compatibility: Confirm the part fits your specific winch model (MW 160E-S/CU1G3 or MW 500/52 E HWF 52) and serial number (e.g., 41470/41471 for MW 160, 39485/39486 for MW 500) to avoid compatibility issues.
On-Site Failure Judgment & Maintenance Standards: To identify component failure early, watch for these clear signs: 1) Brake Lining Failure: Reduced stopping power, excessive heat from the winch drum, or visible wear on the lining—replace immediately to prevent loss of control. 2) Rivet Failure: Loose brake linings, unusual noise during braking, or stripped rivet heads—inspect all rivets during maintenance and replace any that show damage. 3) Bearing Failure: Unusual grinding noise, increased friction when rotating the winch drum, or overheating—lubricate first; if the issue persists, replace the bearing. 4) Grease Nipple Failure: Clogged or broken nipples, leading to inadequate lubrication—clean or replace nipples to prevent bearing damage. When repairing, always use the correct torque specifications (28 ft-lbs for rivets, 45 ft-lbs for grease nipples) and replace parts with identical models to maintain performance.
Quality Assurance & Traceability
We understand that trust is everything when it comes to drilling site parts—one faulty component can put your team and operation at risk. That’s why every part undergoes a rigorous 6-step quality control process: raw material inspection (verifying alloy composition and material grade), dimensional testing (ensuring compliance with Rolls-Royce specs), load and fatigue testing (simulating real-world drilling conditions), heat treatment (for hardness and durability), corrosion testing (salt spray and chemical exposure), and final packaging (protecting parts during shipping). All materials are fully traceable—each part comes with a batch number that links to its material certification, including hardness test results, load test data, and compliance with industry standards. Our commitment to quality means you can rely on these parts to perform consistently, even in the harshest drilling environments, reducing the risk of unplanned downtime and safety incidents.
