Precision-Engineered Deep Groove Ball Bearing 6306/6708 – Industrial-Grade Performance
Ultra-Durable Chrome Steel Construction – High-carbon GCr15 material ensures superior hardness (HRC 60-65) and wear resistance for extended service life under heavy loads. Optimized Raceway Design – Precision-ground grooves minimize friction, enabling smooth rotation at speeds up to 10,000 RPM with low noise/vibration. Versatile Application Scenarios – Ideal for electric motors, automotive transmissions, conveyor systems, agricultural machinery, and HVAC equipment. Strict QC Compliance – Each bearing undergoes rigorous ISO 9001 testing for radial clearance (C3/C4 standards) and ABEC-1 tolerance to guarantee consistent performance. Global Bulk Supply Advantage – Factory-direct pricing with MOQ flexibility (cases/pallets/containers), backed by 24/7 logistics support for urgent OEM/wholesale orders. Corrosion-Resistant Sealing Options – Available with ZZ metal shields or 2RS rubber seals for dust/moisture protection in harsh environments.
Note:
Compatible with standard 6306 (30x72x19mm) and 6708 (40x68x15mm) dimensions – interchangeble with SKF/NSK equivalents at 40% cost savings.
