Technical Datasheet: F-554185.01 INA Needle Roller Bearing

1. Dimensional Specifications (ISO 3061 Standard)
F-554185.01 INA single drawn cup needle roller bearing: Bore d=35 mm, outer diameter D=42 mm, overall width C=25 mm, fillet radius r=0.6 mm. Tolerance grade P0 precision matched with automotive transmission standards; bore tolerance 0/-0.010 mm, outer ring tolerance 0/-0.012 mm. Equipped with 22 high-precision needle rollers of 3 mm diameter, dense roller layout for enhanced radial load capacity; thin-wall stamped outer cup saves installation space for compact assemblies.
2. Material Composition & Mechanical Performance
Drawn cup outer ring: Cold rolled high-carbon steel DC04, tensile strength ≥420MPa, excellent formability and surface rigidity. Needle rollers: GCr15 bearing steel, HRC 60–64, ultra-high hardness, outstanding wear resistance and contact fatigue strength. Retainer: Stamped low-carbon steel cage with surface phosphating treatment, low friction, stable roller separation and anti-rust performance. GCr15 rolling elements deliver long fatigue life under cyclic heavy radial loads, ideal for compact power transmission systems.
3. Core Manufacturing Processes
1. Stamping & deep drawing: Precision sheet metal forming to ensure uniform thin-wall cup thickness without cracking.
2. CNC fine turning: Machining matching surfaces to tight dimensional tolerances.
3. Vacuum heat treatment: Quenching + low-temperature tempering to stabilize hardness and minimize deformation.
4. Raceway grinding: Micro-grinding for smooth contact surfaces with Ra ≤0.025 μm.
5. Roller superfinishing: Eliminates surface burrs, reduces friction and running noise. All procedures comply with INA original manufacturing standards and ISO 3290.
4. Service Life Performance
Basic dynamic radial load rating Cr=32.6 kN, static load rating C0r=40.1 kN, calculated under ISO 281:2019. Standard working conditions: radial load ≤0.3Cr, operating temperature -30℃~120℃, continuous proper lubrication; nominal L10 service life ≥31,000 working hours. Major life-limiting factors: instantaneous overload, lubricant depletion, particle contamination, shaft ovality and misalignment.
5. Industrial Application Fields
INA F-554185.01 compact needle roller bearing is specially designed for automotive power assemblies, core industries including passenger car manual transmission, gearbox shift mechanism, engine auxiliary actuators, small construction hydraulic pumps, textile looms and light industrial compact gear reducers. Its thin-wall compact structure solves space-limited installation demands, while dense needle roller arrangement provides stable heavy radial load bearing capacity.
6. Routine Maintenance Standards
Lubrication interval: Every 150 working hours for high-speed transmission environments; 350 hours for low-speed stable operation. Recommended lubricant: EP2 high-pressure automotive lithium grease, filling 25%–35% of bearing internal clearance. Monthly compressed air cleaning to remove metal debris; regular inspection for roller surface spalling, cup deformation and grease deterioration. Abnormal noise or continuous temperature rise over 32℃ above ambient requires immediate replacement.
7. Installation Guidelines
Pre-installation: Clean shaft and housing bore, remove burrs and metal residues. Installation: Press fit outer cup evenly via a flat pressing tool, avoid direct impact on roller assemblies. Coaxiality error limited below 0.015 mm; mounting auxiliary locking sleeve torque 18–22 N·m. Post-installation test: Rotate shaft manually to check smooth operation without jamming. Wear anti-oil gloves during assembly to prevent grease contamination and surface scratches.
