Product Overview: The UK 308 Heavy-Duty Insert Bearing
The UK 308 is a robust insert ball bearing designed for demanding applications requiring secure shaft mounting. Part of our UK 300 Series, this bearing features a tapered bore and is intended for use with an H 2308 adapter sleeve, allowing it to be securely fixed onto a 35mm shaft. With an outer diameter of 90mm and a width of 52mm, its heavy-duty construction provides superior load-carrying capacity compared to standard insert bearings. The spherical outer surface allows it to compensate for initial static misalignment when installed in a compatible Bearing Housing, making it a versatile and reliable choice for a wide range of industrial and agricultural machinery.
Key Features of the UK 308 Bearing
- Tapered Bore Design: Ensures a tight, concentric fit on the shaft when mounted with the corresponding adapter sleeve, preventing slippage under high loads or vibrations.
- Heavy-Duty Series: Belongs to the 300 series, offering increased radial and axial load capacity for more demanding operating conditions.
- Adapter Sleeve Mounting: Facilitates easy installation and removal on commercial-grade shafts, providing a powerful grip.
- Self-Aligning Capability: The spherical outer ring allows for initial static angular misalignment with the housing, simplifying assembly and reducing stress on the bearing.
- Enhanced Sealing: Equipped with an effective seal and flinger design to protect against contamination and retain lubricant, extending service life.
- Re-lubrication Feature: Includes a lubrication groove and oil hole in the outer ring for convenient maintenance and longer operational life.
Common Applications
- Agricultural Equipment: Ideal for use in harvesters, plows, and conveyor systems where robust performance is critical.
- Construction Machinery: Suitable for concrete mixers, conveyors, and other heavy-duty equipment.
- Industrial Fans and Blowers: Provides reliable support for fan shafts, especially in large-scale ventilation systems.
- Mining and Quarrying: Used in crushers, screeners, and conveyors that handle abrasive materials.
- Material Handling Systems: A core component in pulley and roller assemblies for industrial conveyors.
- Textile and Printing Machinery: Ensures stable and smooth operation of rollers and shafts in continuous-duty machines.
Benefits of Using the UK 308
- Superior Shaft Grip: The adapter sleeve mounting provides a 360-degree grip that is more secure than set screw or eccentric locking collar types.
- Increased Reliability: Heavy-duty design minimizes the risk of premature failure in high-load environments, reducing downtime.
- Simplified Installation: Accommodates initial shaft misalignment, making it easier to install in various housing types like pillow blocks and flange units.
- Extended Component Life: The robust construction and effective sealing protect both the bearing and the shaft from wear and contamination.
- Versatility: Can be used with a variety of housing styles, offering a flexible solution for many different machine designs.
- Improved Performance: Reduces vibration and noise by ensuring a secure and concentric fit on the shaft.
