Product Overview: The UK 208 Tapered Bore Insert Bearing
The UK 208 is a high-performance insert bearing featuring a tapered bore, designed for robust and secure mounting using an adapter sleeve. As a key component in our UK 200 Series, this bearing has a 40mm tapered bore, an 80mm outer diameter, and a 49.2mm inner ring width. It is engineered to be mounted on cylindrical shafts with a corresponding H 2308 adapter sleeve, which ensures a tight, concentric fit and prevents shaft slippage under heavy loads or high speeds. Part of the broader Insert Ball Bearings category, the UK 208 is an excellent choice for applications requiring easy installation and reliable performance.
The outer ring of the UK 208 is spherically shaped, allowing it to be mounted in various bearing housings, such as P Series pillow blocks or F Series flange units. This design compensates for initial static misalignment between the shaft and housing, reducing stress on the bearing and enhancing machinery longevity. Our UK series bearings are manufactured to precise standards, ensuring they meet the demands of challenging industrial environments.
Key Features of the UK 208 Bearing
- Tapered Bore Design: Allows for secure mounting with an adapter sleeve, providing a 360-degree grip on the shaft.
- Spherical Outer Ring: Enables initial static self-alignment when fitted into a corresponding housing, simplifying installation.
- Adapter Sleeve Mounting: Facilitates easy mounting and dismounting on commercial-grade shafts. The H 2308 is the standard sleeve for this bearing.
- Re-lubrication Capability: Equipped with a lubrication groove and hole on the outer ring for easy maintenance and extended service life.
- Robust Sealing System: Features integral seals on both sides to protect against contaminants and retain lubricant effectively.
- High-Quality Construction: Manufactured from premium bearing steel for exceptional durability and load-carrying capacity.
Common Applications
- Agricultural Machinery: Widely used in harvesters, combines, plows, and other farm equipment where reliability is crucial.
- Conveyor Systems: Ideal for supporting shafts in roller conveyors, belt systems, and material handling equipment.
- Industrial Fans and Blowers: Provides stable support for fan shafts in ventilation and air-handling units.
- Construction Equipment: Suitable for machinery such as concrete mixers, compactors, and rollers.
- Food and Beverage Processing: Used in packaging lines, bottling machines, and food conveyors.
- Textile Machinery: Ensures smooth operation in spinning frames, looms, and other textile equipment.
- Mining and Quarrying: Capable of withstanding harsh conditions in screening equipment and crushers.
Benefits of Using the UK 208 Bearing
- Enhanced Shaft Grip: The adapter sleeve mounting provides a superior and more secure fit compared to set screw locking methods.
- Improved Machine Reliability: Reduces vibration and operational noise, leading to smoother performance and fewer breakdowns.
- Simplified Maintenance: The re-lubrication feature allows for easy grease application, prolonging the bearing's operational life.
- Increased Durability: Effective seals prevent the ingress of dirt and moisture, making it suitable for demanding environments.
- Versatile Housing Compatibility: Can be used with a wide variety of pillow block, flange, and take-up unit housings.
- Cost-Effective Solution: The combination of easy installation, long service life, and reduced maintenance needs offers excellent long-term value.
