7306AC Single Row Angular Contact Ball Bearings For Industrial Equipment
The 7306AC is a single - row angular contact ball bearing, designed around "composite load bearing + high - speed precision operation", and suited for scenarios demanding high axial rigidity and rotational speed.
| Aspect | Details |
|---|---|
| Dimensions | Bore: 30 mm (06*5 = 30 mm in model "7306"); Outer diameter: 72 mm; Width: 19 mm. |
| Contact Angle | α=25° (AC type, superior axial load capacity vs. 15° C type, fit for medium-high axial loads). |
| Rated Loads | Dynamic load Cᵣ=32.8 kN; Static load C₀ᵣ=20.4 kN (supports medium-heavy loads). |
| Limit Speed | Grease lubrication: ≤8500 rpm; Oil lubrication: ≤12000 rpm (low-friction design enables high speed). |
The single-row angular contact structure handles radial + unidirectional axial loads (25° contact angle boosts axial capacity over 15° C type).
Optimized ball-raceway contact + optional brass/steel/nylon/phenolic cages reduce friction, suiting high-frequency motors, machine tool spindles, etc.
Manufactured to P5 grade or higher, the 25° contact angle enhances axial rigidity and reduces vibration, ideal for centrifugal separators, indexers, etc.
- Industrial Equipment: Machine tool spindles (cutting), high-frequency motors (driving), gas turbines (power), centrifugal separators (high-speed separation);
- Transportation: Front wheels of small cars (steering), differential pinion shafts (transmission);
- General Machinery: Booster pumps (fluid transfer), food machinery (processing), low-noise cooling towers (ventilation).
