NSK6002ZZC4Deep Groove Ball Bearing – Straight Bore, 15 mm ID, 32 mm OD, 9 mm Width, Steel Shields Both Sides, C4 Internal Clearance

Product Description

What this part is: NSK 6002ZZC4 single-row deep groove ball bearings, shielded both sides, in C4 internal clearance. Series: 6000. Bore: 15 mm. Outside Diameter: 32 mm. Width: 9 mm. Bore Type: Straight. Rolling Elements: Ball. Closure Type: Steel shields both sides. Decoding the designation: 6002 — NSK’s number for the ISO 6002 size, 15 x 32 x 9 mm. ZZ — pressed steel shields on both faces. On NSK these are non-contact metal shields. C4 — radial internal clearance one band wider than C3 and two wider than CN. What these specs mean in practice: Dynamic Load Rating: 6,150 N (6.15 kN) per bearing. Static Load Rating: 2,840 N (2.84 kN) per bearing. Limiting Speed: 26,000 r/min on grease. Internal Clearance: C4. Precision Class: ISO Normal, ABEC 1. Cage Material: Steel. Cage Type: Pressed. Chamfer r min: 0.3 mm. Mass: 0.031 kg each. C4 clearance leaves more room in the bearing before it is mounted, which is what a heavy shaft interference fit or a large temperature difference between inner and outer ring consumes. It is the clearance chosen for electric motors, hot running gearboxes and fan shafts, where a CN bearing would end up preloaded once the assembly reaches operating temperature. Mounting data: Shaft abutment diameter da: 17 mm minimum, 19 mm maximum. Housing abutment diameter Da: 30 mm maximum. Shaft or housing fillet radius ra: 0.3 mm maximum. Quantity and configuration: Unit Quantity: 2 Pcs. Two single bearings in the same clearance class, suited to the two ends of a short shaft. Interchange guidance: Cross-references: SKF 6002-2Z/C4, FAG 6002-2Z-C4, Koyo 6002-2ZC4. Searchable variants of the designation: 6002ZZC4, 6002-ZZ-C4, 6002 ZZ C4, 6002ZZ, 6002Z. A 6002ZZ in CN or C3 shares the same envelope and ratings and differs in the fitted clearance band.
