Key Specifications & Benefits of SKF High-Speed Deep Groove Ball Bearings (62304–62307-2RS1)
| Description | Core Value |
|---|---|
| Model Range | 62304-2RS1 to 62307-2RS1 — standardized, globally interchangeable SKD/ISO-compliant sizes |
| Sealing & Lubrication | Double rubber seals (2RS1) + pre-greased with SKF LGMT 2 — zero maintenance, extended service life |
| Material & Hardness | High-purity GCr15 bearing steel, hardened to 60–64 HRC — superior fatigue resistance |
| Speed Capability | Optimized internal geometry & cage design — up to 18,000 rpm (62304), ideal for high-RPM motors & spindles |
| Load Performance | Radial load capacity: 12.7–29.6 kN — stable under dynamic shock and continuous operation |
| Dimensional Accuracy | P6 precision grade (ABEC-3), Δdmp/ΔDmp ≤ 8 μm — ensures quiet, vibration-free rotation |
| Origin & Traceability | Manufactured in Germany/Sweden/Japan — full batch traceability per ISO 9001 & IATF 16949 |
| Application Scope | Industrial pumps, HVAC fans, CNC spindles, electric vehicle drivetrains, food-grade conveyors |
| Differentiator vs. Generic Brands | SKF’s proprietary raceway superfinishing reduces friction by 22% and extends L10 life by ≥35% |
| FAQ: “Are these genuine SKF?” | Yes — supplied with official SKF hologram label, serial-numbered packaging, and digital certificate upon request |
Engineered for reliability where uptime matters most — these bearings deliver measurable reductions in energy loss, noise, and unplanned downtime. Trusted by Tier-1 OEMs across Europe and Asia.
