SKF 6003 TN9/C3 1 Row Deep Groove Ball Bearing - 17 mm ID, 35 mm OD

This deep-groove ball bearing is designed to support radial loads in rotating equipment used across automation, electronics and mechanical systems. It operates as a single-row unit with a cylindrical bore and an open end, suited to high-speed shafts where moderate static support is required. The non-metallic cage reduces friction and helps maintain smooth operation under continuous rotation.

• C3 internal clearance improves thermal expansion tolerance
• Dynamic load capacity 6.37 kN supports sustained radial forces
• Static load rating 3.25 kN allows reliable holding under stoppage
• Limiting speed 28,000 r/min enables high-speed applications
• Non-metallic cage reduces noise and lowers frictional losses

• Suitable for precision motor spindles in automation equipment
• Ideal for high-speed fans and centrifugal blowers in electronics cooling
• Used with rotary encoders requiring low-friction rotation
• Can be used for light-duty gearbox input shafts in machinery
• Suitable for instrument drives and small electromechanical actuators

The C3 internal clearance provides extra running play to accommodate thermal growth and slight misalignment during high-speed operation.

The non-metallic cage minimises metal-to-metal contact, reducing wear rates and potentially extending re-lubrication intervals in well-sealed systems.

The bearing is rated to run up to 28,000 r/min

An open end allows easier Visual inspection and lubrication access but requires appropriate shielding if used in contaminated environments.
