Product Overview: The UC 203 Insert Ball Bearing
The UC 203 bearing is a fundamental component within our UC 200 Series UC Series and a prime example of Insert Ball Bearings. This versatile bearing is designed for efficient and reliable performance, featuring a nominal bore diameter of 17mm, an outer diameter of 47mm, and an overall width of 31mm. Unlike standard deep groove ball bearings, the UC 203 is specifically engineered with an extended inner ring, which often includes grub screws or an eccentric locking collar for secure shaft attachment. This design simplifies mounting and reduces the need for precision machining of the shaft shoulder, making it highly adaptable for various industrial applications.
As a leading provider of industrial bearings and mechanical parts, we ensure that our UC 203 bearings adhere to stringent industry standards. Their robust construction and integrated sealing mechanisms make them ideal for environments where contamination is a concern, providing smooth operation and extended service life.

Key Features of the UC 203 Bearing
- Extended Inner Ring: Designed with a wider inner ring on one or both sides, providing a larger contact area for shaft support and stability.
- Secure Shaft Attachment: Typically features two grub screws (setscrews) or an eccentric locking collar for quick and firm attachment to the shaft, preventing slippage.
- Integrated Sealing: Equipped with effective seals to protect the internal components from dust, dirt, and moisture, extending the bearing's lifespan.
- Pre-Lubricated & Re-lubricatable: Often supplied pre-lubricated and includes a grease nipple for easy re-lubrication, ensuring continuous optimal performance.
- Spherical Outer Surface: The outer ring is spherically ground, allowing the bearing to accommodate initial misalignment within a compatible bearing housing.
- Durable Construction: Manufactured from high-quality bearing steel for excellent wear resistance and long-term reliability in demanding industrial settings.
