1. Dimensional Parameters (SEO: HK354220 bearing dimensions)
- Inner diameter (d): 35mm | Outer diameter (D): 42mm | Width (B): 20mm
- Minimum chamfer (rmin): 0.6mm | Mass: 0.0405kg
- Tolerance class: P0 (ISO 492), standard precision
- Dynamic load rating (C): 27.4kN | Static load rating (C0): 42.3kN
- Limiting speed (grease): 14,000 r/min
- Design: Open-end drawn cup, full complement needle rollers (no cage)
2. Material Specification (SEO: needle roller bearing materials)
- Outer cup (drawn cup): High-carbon cold-rolled steel (SPCC/1010), deep-drawn & hardened to 58–62 HRC, offering high wear resistance & dimensional stability.
- Needle rollers: High-carbon chromium bearing steel (GCr15/AISI 52100), vacuum-melted, 61–65 HRC hardness, superior fatigue strength & anti-wear performance.
- No inner ring / No cage: Full-complement design maximizes roller count for ultra-high load capacity.
3. Core Manufacturing Process (SEO: precision bearing manufacturing)
- Deep drawing: Thin-wall outer cup formed via precision stamping for uniform wall thickness.
- Heat treatment: Controlled atmosphere quenching ensures uniform hardness & minimized distortion.
- Grinding & superfinishing: Raceway finished to Ra ≤ 0.05μm for low friction & smooth rotation.
- Roller assembly: High-precision rollers sorted for tight diameter tolerance (≤ 2μm), ensuring even load distribution.
4. Service Life (SEO: bearing life calculation ISO 281)
Under standard conditions (10,000 r/min, 30% dynamic load, clean grease lubrication), L10 basic rating life (90% reliability) = 25,000 hours, calculated per ISO 281:2007. Key factors: lubrication quality, contamination, installation alignment & operating temperature.
5. Applications & Industries (SEO: needle roller bearing applications)
Widely used in automotive transmissions, engine components, power tools, textile machines, office equipment & small industrial gearboxes. Suited for space-constrained, high-rigidity & heavy radial load environments—core advantages: ultra-compact design, high load density & cost-effective performance.
6. Maintenance & Lubrication (SEO: bearing maintenance guide)
- Interval: Relubricate every 800–1,200 operating hours.
- Lubricant: NLGI 2 lithium complex grease or ISO VG 46–68 gear oil; fill 15–25% of free space.
- Cleaning: Use kerosene; avoid corrosive detergents.
- Inspection: Check noise, vibration & temperature; replace if abnormal wear or lubricant degradation occurs.
7. Installation Notes (SEO: bearing installation best practices)
- Prep: Clean housing, remove burrs; verify housing bore tolerance H7 & shaft tolerance p6.
- Mount: Press-fit outer cup with hydraulic press (no hammering); axial alignment ≤ 0.02mm.
- Torque: Housing end-cap bolts: 8–12 N·m.
- Post-install: Rotate manually to confirm smooth operation; running temp ≤ 70°C.
- Safety: Wear gloves & goggles; use press fixtures to prevent cup deformation.
