Product Overview: UC 308 Insert Ball Bearing
The UC 308 is a robust and widely used insert ball bearing, designed for straightforward installation and reliable performance in a variety of mounted applications. As a key component in our UC 300 Series, this bearing features a 40mm bore diameter, a 90mm outer diameter, and a 52mm inner ring width. Its most notable characteristic is the extended inner ring with two set screws, which allows for simple and secure locking onto the shaft. The outer ring is spherically designed to fit into a corresponding housing, which accommodates initial static misalignment, ensuring smooth operation even when perfect alignment is not possible.
As part of the Insert Ball Bearings category, the UC 308 is pre-lubricated and sealed, making it a low-maintenance solution for demanding environments. It is engineered to be mounted within various types of bearing housings, such as pillow block (P series), flange (F series), and take-up (T series) units, providing a versatile and cost-effective bearing arrangement.
Key Features of the UC 308 Bearing
- Set Screw Locking: Features two grub screws on the extended inner ring for a secure and direct grip on the shaft.
- Spherical Outer Surface: Allows the bearing to pivot within the housing, compensating for initial static misalignment between the shaft and the housing structure.
- Pre-Lubricated and Sealed: Arrives ready to install with factory-filled grease and features integral seals to protect against contaminants and retain lubricant.
- Durable Construction: Manufactured from high-quality bearing steel to ensure high durability and a long service life under heavy loads.
- Relubrication Capability: Equipped with a lubrication groove and oil hole on the outer ring for easy relubrication, extending its operational life in harsh conditions.
- Easy Installation: Designed for quick and simple mounting and dismounting, reducing machinery downtime.
Common Applications of UC 308 Bearings
- Agricultural Machinery: Ideal for use in harvesters, conveyors, plows, and other farm equipment where reliability is crucial.
- Conveyor Systems: Widely used in roller and pulley assemblies for material handling across various industries.
- Industrial Fans and Blowers: Provides stable support for rotating shafts in air handling units.
