Product Overview: The UK 218 Heavy-Duty Insert Bearing
The UK 218 is a robust and reliable insert bearing designed for demanding industrial applications. As a key component in our UK Series, this bearing features a tapered bore and is intended for use with an H 2318 adapter sleeve, ensuring a secure and concentric fit on an 80mm shaft. With an outer diameter of 160mm and a width of 96mm, the UK 218 is built to handle significant radial loads and moderate thrust loads in either direction. Its spherical outer ring allows it to be mounted in various bearing housings, where it can compensate for initial static misalignment between the shaft and the housing, a critical feature for long machinery life.
This type of insert ball bearing is pre-lubricated and sealed, offering a maintenance-friendly solution for a wide range of equipment. The adapter sleeve mounting method provides superior grip compared to set screw types, making it ideal for applications with high speeds or vibration. Trust the UK 218 for exceptional performance in challenging environments.
Key Features of the UK 218 Bearing
- Tapered Bore Design: Facilitates mounting with an adapter sleeve for a powerful 360-degree grip on the shaft.
- Heavy-Duty Construction: Manufactured from high-quality bearing steel to withstand heavy loads and harsh operating conditions.
- Spherical Outer Surface: Allows for initial angular misalignment, reducing stress on the bearing and extending the service life of machinery.
- Adapter Sleeve Mounting: Provides excellent concentricity and prevents shaft damage, suitable for commercial or ground shafts.
- Sealed for Life: Equipped with integral seals to protect against contaminants like dust and moisture, and retains grease for long life.
- Pre-Lubricated: Ready to install right out of the box, minimizing installation time and effort.
Common Applications
- Agricultural Machinery: Widely used in harvesters, combines, and other farm equipment where robust performance is essential.
- Conveyor Systems: Ideal for pulley and roller applications in material handling systems due to its high load capacity.
- Construction Equipment: Provides reliable support in cement mixers, road rollers, and other heavy machinery.
- Industrial Fans and Blowers: Ensures stable and smooth operation in large-scale ventilation systems.
- Mining and Quarrying: Capable of withstanding the vibration and heavy loads found in crushers, screens, and conveyors.
- Textile and Paper Mills: Used in roller applications requiring reliable and consistent performance.
- Food and Beverage Processing: Suitable for machinery where durability and resistance to contamination are important.
Benefits of Using the UK 218 Bearing
- Enhanced Shaft Grip: The adapter sleeve provides a uniformly tight fit, reducing fretting corrosion and making it suitable for shafts that are not perfectly sized.
- Improved Equipment Reliability: Self-aligning capability prevents premature bearing failure and damage to other components caused by shaft deflection.
- Simplified Installation & Dismounting: Adapter sleeves make it easy to mount and remove the bearing from any position on a shaft.
- Increased Load Capacity: Engineered to support higher radial loads than standard deep groove ball bearings of similar dimensions.
- Reduced Maintenance Requirements: The sealed and greased design eliminates the need for regular re-lubrication, lowering operational costs.
- Versatile Housing Compatibility: Can be fitted into a variety of housing types, including pillow blocks (P-type), flange units (F-type), and take-up units (T-type).
