Product Overview: The UC 208 Insert Bearing
The UC 208 is a robust and widely used insert bearing featuring a 40mm bore diameter, 80mm outer diameter, and 49.2mm width. As a key component in our UC 200 Series, this bearing is designed for simple and effective mounting. It belongs to the versatile family of Insert Ball Bearings, which are essentially modified deep groove ball bearings designed to fit into various bearing housings. The UC 208 features a spherical outer diameter that allows it to tolerate initial static misalignment when mounted in a housing, ensuring smooth operation. Its inner ring is extended on one side and equipped with two set screws, providing a secure and reliable locking mechanism onto the shaft.
Key Features of the UC 208 Bearing
- Set Screw Locking: Features two grub screws positioned 120 degrees apart on the extended inner ring for firm and secure attachment to the shaft.
- Spherical Outer Ring: The convex outer surface allows for initial static misalignment when installed in a corresponding concave housing, preventing binding and premature wear.
- Extended Inner Ring: Provides enhanced shaft support and stability, reducing the risk of shaft tilting.
- Durable Construction: Manufactured from high-grade bearing steel for excellent durability and resistance to wear under operational stress.
- Pre-Lubricated and Sealed: Comes pre-filled with grease and equipped with seals on both sides to retain lubricant and protect against contaminants, making it ready for immediate installation.
Common Applications
- Conveyor Systems: Widely used in rollers and drives where easy installation and reliability are crucial.
- Agricultural Machinery: Ideal for equipment such as combines, balers, and seeders that operate in demanding and dusty environments.
- Food and Beverage Processing: Suitable for machinery where reliable operation and protection against contamination are necessary.
- Packaging Equipment: Ensures smooth and consistent motion in automated packaging lines.
- HVAC Systems: Commonly found in fans, blowers, and air handling units for reliable shaft support.
- Textile and Printing Machinery: Provides stable rotational support for rollers and shafts in high-speed applications.
Benefits of Using the UC 208
- Simplified Installation: The set screw locking system allows for quick and easy mounting and dismounting without specialized tools.
- Cost-Effective Assembly: Eliminates the need for shoulders, locknuts, or adapter sleeves, reducing overall assembly complexity and cost.
- Enhanced Machine Uptime: The ability to accommodate initial misalignment reduces stress on the bearing, extending its service life and minimizing downtime.
- Reduced Maintenance Needs: Being sealed and greased for life significantly lowers maintenance requirements.
- Versatile Compatibility: Designed to be used with a variety of housing types, including pillow block (P 208), flange (F 208), and take-up units.
