Product Description

What this part is

SNR 7220CDUJ74 super-precision angular contact ball bearing. Bore: 100 mm. Outside Diameter: 180 mm. Overall Width: 34 mm. Series: 7200. Number Of Rows: 1. Rolling Elements: Ball. Bearing Material: Bearing steel. Closure Type: Open. Bore Type: Straight.

Decoding the designation

Contact Angle: 15°. Preload: Light. Precision Class: ABEC 7 / P4. Cage Material: Phenolic. Cage Type: Outer-ring land-riding. Mounting Arrangement: Universal. Base Number: 7220. Part Number: 7220CDUJ74.

What these specs mean in practice

Dynamic Load Rating: 145.0 kN. Static Load Rating: 134.0 kN. Limiting Speed: 8500 rpm. A 15° contact angle favours speed and radial rigidity over thrust capacity. Light preload holds the rings in defined contact for running accuracy and shaft location while keeping heat generation low at speed. Internal Clearance: N/A — the bearing is set by preload.

Cage and lubrication

The phenolic cage is guided on the outer-ring land, which keeps it stable at high speed and gives it low mass and good dry-running tolerance. Lubricant: grease or oil. Max Temp: 120°C. Min Temp: -30°C. Item Weight: 7.70 lbs.

Configuration

Mounting Arrangement: Universal. Universally ground faces let the bearing run singly or be set against another universally ground 7220C in back-to-back, face-to-face or tandem.

Interchange guidance
