Product Details
Key Specifications & Benefits
| Description | Core Value |
|---|---|
| Model Range: 62304-2RS1 to 62307-2RS1 | Precision-engineered deep groove ball bearings for seamless interchangeability and system scalability |
| Single-Row Radial Design | Optimized for high-speed rotation with minimal friction and heat generation |
| Double Rubber Seal (2RS1) | Superior dust/moisture resistance — extends service life by up to 2.5× vs. open or metal-shielded types |
| Bearing Steel Construction | High-purity, vacuum-melted steel ensures fatigue resistance and dimensional stability under dynamic loads |
| Contact Angle: 0° | True radial load capacity + moderate axial load capability — ideal for general-purpose machinery |
| Dimensions (e.g., 62305-2RS1): 25×52×15 mm | Compact yet robust — fits standard OEM housings across industrial, automotive & HVAC applications |
| Origin: Germany/Sweden/Japan | Manufactured to ISO 9001 & ABEC-1 precision standards — traceable quality control |
| HS Code 8482102000 | Compliant with global import regulations — smooth customs clearance for EU, US & ASEAN markets |
| 1M Units Annual Capacity | Reliable bulk supply — no lead-time surprises for distributors and OEMs |
| NTN Brand Licensed | Backed by NTN’s global warranty & technical support — unlike generic uncertified alternatives |
Engineered for demanding environments — from conveyor systems and pumps to electric motors and agricultural gearboxes. These bearings deliver exceptional rotational accuracy, low noise (≤28 dB), and >50,000-hour L10 life under rated load. Unlike budget clones, our SKf-aligned 2RS1 series features laser-etched batch codes, full material certs, and grease pre-filled with NLGI #2 lithium complex for extended maintenance intervals.
FAQ: Q: Are these compatible with SKF mounting dimensions? A: Yes — identical ABEC-1 tolerances and housing fits. Q: What’s the max speed rating? A: Up to 12,000 rpm (62304) — consult our engineering sheet for application-specific limits. Q: Do you offer custom packaging or branding? A: Yes — white-label options available for qualified partners.
