SKF 3216 A 2 Row Ball Bearing - 80 mm ID, 140 mm OD 44.4 mm Race Width

This angular contact ball bearing is designed to support combined radial and axial loads in rotating machinery commonly found in automation, electronics and mechanical systems. It employs a dual-row configuration with steel rolling elements and a parallel bore to provide stable support for shafts operating at elevated speeds, while an open-ended design facilitates inspection and lubrication access.

• 30° contact angle enhances axial load-carrying capacity
• 4300 r/min limiting speed facilitates high-speed operation
• 106 kN dynamic load rating extends service under fluctuating loads
• 95 kN static load rating resists deformation under heavy stationary loads
• Sheet-metal cage reduces friction and improves heat dissipation
• CN internal clearance allows precise preload and thermal compensation

• Suitable for spindle assemblies in automated manufacturing equipment
• Ideal for servo motor shafts requiring axial and radial support
• Used with rotary stages in precision electronics inspection systems
• Can be used for gearbox input shafts subject to combined loading
• Used for industrial fans and blowers operating at high rotational speeds

The balls are steel, which provides high hardness and predictable wear characteristics under standard lubrication regimes.

A parallel bore permits straightforward shaft fitment and alignment using standard press or shrink-fit methods without tapered-housing adjustments.

The open design allows direct re-lubrication and Visual condition checks without removal of housing covers.

The sheet-metal cage conducts heat away from the raceways more efficiently than polymer cages, aiding temperature control during sustained high-speed operation.
