Graco 17W954 Bearing Assembly PS/HS plays a pivotal role in high-volume finishing applications, ensuring minimal downtime and consistent output. Precision engineering and robust construction merge to deliver a component that withstands rigorous cycles within professional sprayer systems. Ideal for heavy-duty environments, this bearing assembly supports efficient fluid delivery and stable operation at high pressures. Designed for harsh industrial conditions, it offers chemical resistance against solvents, stable friction coefficients across temperature variations, and optimized sealing to keep abrasives and contaminants at bay.
A multi-row design reduces radial play while optimizing axial load capacity under demanding conditions. Stainless steel retainers and high-purity steel races contribute to exceptional wear resistance and low noise levels. Contact angles are engineered to balance thrust and radial forces, delivering low friction torque and precise rotational control. Proprietary grease channels distribute lubricant evenly, preventing localized overheating. Integral seals resist high-pressure ingress, maintaining internal conditions for thousands of cycles. Geometry enhancements ensure consistent grease retention and easy assembly alignment during maintenance tasks.
Bore diameter measures 0.875 inches (22.225 mm), matching OEM tolerances exactly to ensure slip-free coupling and precise concentricity. Outer race thickness of 0.500 inches (12.7 mm) conforms to pump housing dimensions, reducing vibration at high RPM. Temperature ratings span from –20 °C up to 120 °C, accommodating ambient and fluid extremes. Dynamic load ratings exceed 1,200 N with a static load rating above 900 N, and maximum rotational speeds up to 10,000 RPM. Material hardness reaches 60 HRC, ensuring high fatigue life and compliance with ABEC-3 accuracy standards.
Integrating this bearing assembly within a graco ultra 395 system dramatically reduces wear on drive shafts and housing components. High-precision tolerances minimize mechanical backlash, preserving pump integrity over prolonged usage. Fluid-friendly seals maintain performance across solvent-based coatings and high-viscosity fluids, even under variable seasonal temperatures. Industrial operators will benefit from smoother pump action, fewer unplanned stops and extended intervals between field servicing, making this assembly an asset for continuous production lines and demanding automotive refinishing workflows.
For operators seeking flawless coatings, pairing this assembly with a hvlp paint spray gun yields exceptional results. Low-torque rotation ensures even material flow, preventing pulsation and sputtering at the nozzle. Consistent fluid shearing enhances atomization, reducing overspray and improving pattern control on complex geometries. Stable pump pressure enabled by precision bearings allows multiple layers of base coat and clear coat to be applied with uniform thickness. Enhanced component alignment translates into sharper edge definition and smoother surface finishes across diverse substrates.
Each unit undergoes rigorous inspection to verify dimensional accuracy and surface finish. Quality control protocols include ultrasonic testing, magnetic particle inspection and visual examination under 20× magnification. Designed for seamless retrofitting, this part supports a wide range of industrial machines and hplv paint guns without modification. Materials meet ASTM A485 and ISO 9001 specifications for high-strength, corrosion-resistant bearing steel. Every batch carries a unique lot number and undergoes endurance testing to ensure traceability, fatigue resistance and consistent performance throughout its expected service life.
Regular examination of seal condition and lubricant integrity is recommended every 500 hours of operation. Use compatible grease formulations to avoid chemical breakdown near high-temperature zones. Proper installation requires calibrated torque wrenches (25–30 Nm) and specialized alignment tools to maintain concentricity. Disassembly guides and safety protocols prevent damage during component replacement. Training videos, field guides and on-site audits are available to streamline inspection procedures.
