Experience superior performance with the Graco 17L470 Pulley, a precision idler component designed to enhance pump efficiency and longevity. Built for professional spray systems, this compact unit features a robust steel construction that resists wear and delivers exceptional, consistent results. Optimized for easy installation and minimal maintenance, it perfectly complements airless sprayer setups and delivers reliable operation even under demanding conditions.
Ideal for maintenance and upgrades, the 17L470 ensures optimal material flow through high-pressure filtration assemblies. Its pressed bearing mechanism minimizes friction and heat buildup, supporting consistent output of robust coatings. Whether working with heavy-duty sealers or fine finish layers, this Graco idler pulley is engineered to meet the rigorous demands of professional coatings applications with unmatched reliability, efficiency, and precision.
In fluid handling systems, idler pulleys guide drive belts and maintain consistent tension. Graco 17L470 Pulley, Idler, Bearing Pressed is built to endure harsh industrial environments where abrasive particulates or corrosive chemicals circulate. This precision assembly incorporates pressed bearing technology that provides high dynamic load capacity and minimal radial play, ensuring close tolerances. Machined bores and concentricity control reduce vibration, lessen noise levels, and extend belt life, lowering total cost of ownership and maximizing uptime.
Precision-engineered assemblies like this idler rely on uniform load distribution to prevent premature wear on belts and shafts. A tight radial clearance of less than 0.015 inches reduces slippage while supporting rotational speeds up to 3,600 RPM. Integration with any pump drive can benefit from complementary accessories, including graco spray hose solutions that preserve fluid integrity and simplify hose routing. Low-friction seals, combined with sealed-for-life bearings, eliminate the need for frequent relubrication. Recommended grease type is an NLGI grade 2 lithium-complex that maintains viscosity over broad temperature ranges. Low dynamic friction coefficients below 0.01 help lower torque requirements, improving energy efficiency across varying load profiles.
Material selection exerts a major influence on fatigue resistance under cyclic stress conditions. The pulley features thermoset composite flanges with exceptional dimensional stability at temperatures up to 200 °F, preventing warping or out-of-round conditions. Flange surfaces undergo anodic oxidation to increase wear resistance and improve belt grip, while bearing steel meets 52100 hardness specifications for superior load endurance. Steel-backed, pressed bearing cups are treated with anti-corrosion plating to guard against salt spray and chemical washdown. Maintenance technicians appreciate the integrated keyway and precision ground bore, which guarantee secure mounting. Complementary safety components such as graco tip guard simplify risk mitigation by shielding exposed rotating elements from accidental contact.
Installation protocols emphasize simplicity and alignment accuracy to ensure proper belt tension. Proper setup uses a laser alignment tool and a calibrated torque wrench to apply 15–20 lb-ft of preload on mounting bolts. During routine service, bearing condition is assessed by monitoring noise and radial play before relubrication. Incorporating stringent cleaning procedures and high-quality filtration measures, including graco filters and strainers, prevents particulate ingress and extends component life. Adhering to recommended maintenance intervals safeguards performance and reliability in continuous operations.
Adaptability is another hallmark of this pulley idler design. Graco offers retrofit kits with custom spacers and bracket adapters that align the idler precisely within the existing pump frame. Engineers benefit from detailed CAD models and dimensional drawings available for download, facilitating rapid integration into project plans. 3D laser scanning ensures each retrofit component matches the original equipment envelope, and belt selection charts help match V-belts or synchronous belts to application torque requirements. Field data indicates that optimizing idler tension can boost power transmission efficiency by up to 10 percent, reducing motor current draw and lowering energy consumption. Detailed integration guidelines support both horizontal and vertical pump orientations, simplifying installation planning for maintenance and operations teams.
Every unit undergoes factory testing to validate durability under real-world stresses. Simulated fatigue testing evaluates bearing life, while thermal cycling between –20 °F and 250 °F confirms seal integrity across extreme temperature swings. Salt-spray exposure per ASTM B117 verifies corrosion resistance, and vibration analysis using ISO 5347 protocols keeps noise emissions under 75 dBA at full speed. Each assembly carries traceable lot and serial information to streamline inventory management and lean maintenance practices. Quality assurance documentation accompanies every shipment, ensuring compliance with industry standards.
Graco customers gain access to extensive technical documentation, including step-by-step installation manuals, alignment checklists, and troubleshooting guides. Expert field engineers provide hands-on training workshops and certification courses to empower maintenance teams and ensure best practices. Ordering genuine replacement parts like this idler bearing assembly eliminates compatibility risks and preserves system integrity under rigorous operating conditions.
