Engineered for reliability in demanding automotive air conditioning compressors, this bearing delivers OEM-level performance at competitive trade pricing. Its double-row radial design ensures superior load distribution and shock resistance — critical for stop-start cycling in modern vehicles. Precision-ground raceways and optimized internal clearance minimize heat buildup and wear, while low-noise cages meet strict Tier-1 supplier acoustic requirements.
Unlike generic alternatives, our bearings undergo full functional validation against NSK and SKF reference specs — including torque consistency, seal integrity, and thermal endurance up to 120°C. Stocked in bulk (1M+ units), ready for fast dispatch worldwide via sea or air.
Frequently Asked Questions:
Q: Is this bearing sealed? A: Yes — 2Z = double metal shields (non-contact, low-torque).
Q: Can it replace SKF 3306-2Z? A: Yes — identical dimensions, load ratings, and ABEC/P0 precision.
Q: What’s the max speed? A: 12,000 rpm (grease-lubricated, ambient 25°C).
