SKF 1303 ETN9 17 mm ID 2 Row Self-Aligning Ball Bearing -, 47 mm OD

This self-aligning ball bearing is designed to accommodate angular misalignment between shaft and housing while supporting rotating assemblies in automation and electrical equipment. It uses spherical outer raceways to maintain operation under shaft deflection and is intended for applications requiring two-row ball contact and an open-end configuration.

• Two-row design provides enhanced load distribution and stability
• Non-metallic cage reduces friction and noise in continuous operation
• CN internal clearance allows precise axial and radial accommodation
• Limiting speed of 20,000 r/min supports high-speed rotating systems
• Dynamic load capacity of 12.7 kN delivers strong fatigue resistance
• Static load capacity of 3.4 kN withstands stationary loads during downtime

• Suitable for motor and drive assemblies in automation lines
• Ideal for precision fans and high-speed spindles in electronics manufacturing
• Used with electrical actuators requiring angular compensation
• Can be used for rotating joints in mechanical handling equipment

It has a cylindrical bore so shafts should be machined for a plain-fit installation without taper seating.

The open ends permit direct inspection and lubrication access, simplifying routine service intervals where re-lubrication is required.

Because it compensates for shaft misalignment, housings should still provide secure axial location and adequate clearance to avoid external preloading that would impair spherical self-alignment.

The balls are steel, which provides conventional hardness and wear characteristics suited to common industrial lubricants and environments where corrosion control is managed.
