Key Specifications & Advantages of RNAV4914–RNAV4920 Needle Roller Bearings
| Description | Core Value |
|---|---|
| Ultra-compact design (e.g., 80×100×30 mm) | Maximizes load capacity in minimal radial space — ideal for tight assemblies |
| Radial-only, high-load needle roller type | Delivers 2.5× higher dynamic load vs. deep groove ball bearings of same size |
| No inner/outer ring (cage + rollers only) | Reduces weight & inertia; enables direct shaft/housing mounting for OEM integration |
| Bearing steel (GCr15) with precision ground rollers | Ensures uniform load distribution and extended service life under shock loads |
| Closed-type sealed construction | Prevents contamination ingress; retains grease longer — low-maintenance operation |
| P0–P2 precision grades & C0/C3/C4 clearance options | Meets strict tolerances for automotive transmissions, industrial gearboxes, and robotics |
| Grease or oil lubrication compatible | Flexible maintenance: pre-lubricated for life or field-replenishable |
| 1M pcs/year production capacity + ISO 9001 certified | Reliable supply chain & consistent quality control — no batch variance |
| HS Code 8482102000 | Made in China (BDL brand) | Compliant with global import regulations; cost-competitive vs. SKF/NSK equivalents |
| OEM/ODM support & technical documentation | Custom engineering assistance — drawings, material certs, test reports on request |
Perfect for automotive CV joints, hydraulic pumps, textile machinery, and compact actuators — where space, weight, and reliability matter most. Unlike standard needle bearings, RNAV49xx series features optimized roller guidance and superior surface hardness (HRC 60–64), reducing wear by up to 40% in high-cycle applications. All units undergo 100% dimensional inspection and noise testing before shipment. Have a custom shaft/housing spec? Send your inquiry now — our engineers reply within 2 hours.
