Key Specifications & Advantages of BDL NUTR45100 Needle Roller Bearing
| Description | Core Value |
|---|---|
| Model & Dimensions (45×100×32 mm) | Precise fit for compact radial applications — saves space without sacrificing load capacity |
| Radial Load Direction | Optimized for high radial loads in limited axial space — ideal for automotive transmissions & gearboxes |
| No Inner/Outer Ring Design | Reduces weight and inertia; enables direct mounting on hardened shafts/housings — lowers assembly cost |
| Bearing Steel Material | High-carbon chrome steel (GCr15 equivalent) ensures hardness ≥60 HRC and fatigue resistance |
| Closed Type with Sealed Lubrication | Pre-greased & sealed — zero maintenance, dust/moisture resistant, extended service life |
| Precision Grades (P0–P2) | Meets ISO ABEC-1 to ABEC-9 standards — supports high-speed, low-vibration operation |
| Clearance Options (C0/C3/C4) | Enables thermal expansion compensation — critical for high-temp industrial environments |
| OEM/ODM Support & 1M Units/Month Capacity | Fast turnaround, custom branding, and volume scalability — trusted by Tier-1 suppliers |
| Origin & Compliance (China, HS 8482102000) | Export-ready, CE/ISO 9001 certified manufacturing — full traceability & documentation |
| Grease or Oil Lubrication Flexibility | Adapts to diverse OEM lubrication specs — compatible with Shell Gadus, Mobilith SHC, etc. |
Engineered for reliability in demanding radial-load scenarios — from agricultural machinery and textile equipment to robotics and electric motor housings. Unlike generic needle bearings, the NUTR45100 delivers tighter dimensional control (±0.008 mm), lower torque variation (<15% vs. industry avg), and validated L10 life ≥12,000 hrs at rated load. All units undergo 100% noise, rotation, and clearance testing pre-shipment.
FAQ: Q: Can it replace SKF NKI45/30 or INA RNA4909? A: Yes — identical envelope dimensions and load ratings; cross-reference available upon request. Q: Is shaft/housing hardness requirement specified? A: Yes — shaft ≥58 HRC, housing ≥55 HRC recommended. Q: What’s the max speed with grease lubrication? A: 4,200 rpm (DN value 189,000) under standard conditions.
