Key Specifications & Benefits of SKF-Grade 608 Deep Groove Ball Bearing
| Description | Core Value |
|---|---|
| Model: 608ZZ (Sealed with double rubber shields) | Superior dust/moisture resistance vs. open or metal-shielded variants |
| Dimensions: 8 × 22 × 7 mm (ID × OD × Width) | Compact, space-saving design ideal for small motors & precision devices |
| Precision Grades: P0 / P6 / P5 / P4 available | Tight tolerances ensure ultra-low vibration & extended service life |
| Lubrication: Pre-filled with high-temp grease (also oil-compatible) | Maintenance-free operation; optimized for continuous high-speed use |
| Noise Level: Ultra-low (≤25 dB at 1800 rpm) | Perfect for quiet appliances, medical equipment & office machinery |
| Material: GCR15 bearing steel (equivalent to SKF 2304/2305 grade) | High hardness (HRC 60–64), fatigue-resistant & corrosion-inhibited |
| Clearance Options: C0 / C2 / C3 | Custom thermal expansion matching — critical for motor applications |
| Load Type: Radial (with moderate axial capacity) | Stable performance under combined loads in electric motors & gearboxes |
| OEM/ODM Support + ISO 9001 Certified Production | Full traceability, batch testing reports & custom packaging on request |
| Stock: Ready-to-ship (1M+ units in inventory) | No lead time delays — same-day dispatch for urgent orders |
Engineered for reliability in demanding applications: power tools, HVAC blowers, robotics joints, conveyor rollers, and industrial automation systems. Unlike generic 608 bearings, ours undergo strict dimensional screening, 100% noise testing, and dynamic load validation per ISO 15242. Have a special requirement?
