SKF 3203 Series Ball Bearing, 17mm Inside Diameter, 40mm Outside Diameter - 3203 ATN9/C3


This ball bearing is a two-row angular contact unit designed for high-speed rotational applications. It features a grooved race and closed-end construction for contained operation, with steel races and steel balls providing load transmission. The product is suitable where paired contact geometry and a defined internal clearance are required for assemblies operating at elevated shaft speeds.

Features and Benefits:


• 16,000 r/min limiting speed for high-speed operation
• C3 internal clearance to accommodate thermal expansion
• 30° contact angle for axial and radial load sharing
• Non-metallic cage reducing friction and noise
• 14.3 kN dynamic load rating for sustained operational loads
• 8.8 kN static load rating for high holding capacity

Applications


• Suitable for high-speed spindles in machining centres
• Ideal for precision rotary tables and indexing units
• Used with servo-driven shafts requiring axial load support
• Can be used for Compact gearboxes with radial constraints
• Suitable for rotary encoders and measurement devices

What bore and outside dimensions does it use for shaft fitting?


The inner diameter is 17 mm and the outer diameter is 40 mm.

What materials contact the rolling elements for durability?


The rings and balls are manufactured from steel, providing robust contact surfaces.

How is axial load capacity influenced by contact geometry?


The 30° contact angle directs axial loads into the bearing, enabling combined axial and radial load transmission.

What raceway form is provided to guide rolling elements?


The bearing uses grooved races to retain ball location and ensure stable rolling paths.

Is the product approved for restricted-substance regulations?


It conforms to RoHS approvals.
