KMB Bearing UC 208/24

The KMB Bearing UC 208/24 is a versatile and high-performance self-aligning bearing unit designed to handle moderate radial loads and accommodate minor misalignments. This bearing is part of the KMB range of pillow block bearings, which are known for their durability, reliability, and ease of installation in various industrial and agricultural applications. With a 24mm bore diameter, the UC 208/24 is ideal for use in smaller machinery, equipment, and systems where space is limited but performance is essential.

Design and Features

1. Self-Aligning Ball Bearing:
   The UC 208/24 features a self-aligning ball bearing, which means it can compensate for minor misalignments between the shaft and housing. This self-aligning feature is crucial in environments where shafts may experience slight angular or parallel misalignments during operation. It reduces the stress on the bearing and extends its service life, ensuring smooth operation in imperfect alignment conditions.
2. Pillow Block Housing:
   The UC 208/24 comes with a pillow block housing made from high-quality cast iron. The housing provides excellent stability and protection for the bearing, reducing vibrations and minimizing the risk of bearing failure. The pillow block design also makes installation easier by allowing secure mounting onto the equipment or machine frame, providing a stable platform for the bearing during operation.
3. Sealed Design for Protection:
   The UC 208/24 features sealed ball bearings on both sides, which protect the bearing’s internal components from dirt, moisture, dust, and other contaminants. The sealed design ensures the bearing operates smoothly and reduces the need for frequent lubrication or maintenance. This makes the UC 208/24 a cost-effective solution in environments where cleanliness is important or where the bearing may be exposed to harsh conditions.
4. Set Screw Mounting:
   The UC 208/24 bearing unit is designed for easy installation with a set screw mounting system. This mounting method allows the bearing to be securely attached to the shaft, preventing it from slipping or rotating during operation. The set screws also ensure proper alignment during installation, reducing the likelihood of misalignment-related issues that can lead to premature wear or failure.
5. Compact Design:
   With a 24mm bore diameter, the UC 208/24 is designed for use in compact and space-constrained applications. Despite its smaller size, it is engineered to handle moderate radial loads while providing the stability and reliability required for consistent operation in industrial and agricultural machinery.
6. Durable Construction:
   The UC 208/24 is built to last, with a robust cast iron housing and high-quality sealed ball bearings. It is designed to withstand heavy-duty applications and to operate effectively even in harsh working environments where exposure to dust, moisture, and contaminants is common. This durable construction ensures long-term performance and reduced downtime due to maintenance.
7. Low Maintenance:
   Thanks to the sealed design, the UC 208/24 bearing unit requires minimal maintenance. The sealed bearings keep contaminants out and retain lubrication, meaning there’s no need for frequent greasing or lubrication. This feature is especially useful in environments where regular maintenance access is difficult or costly, offering a more hands-off solution for machine owners and operators.
8. High Load Capacity:
   Although compact in design, the UC 208/24 bearing unit is designed to handle moderate radial loads. It is ideal for use in machinery that requires steady and reliable bearing support without exceeding the unit’s load capacity. This makes it suitable for smaller conveyor systems, light-duty agricultural equipment, and other industrial applications where consistent load-bearing performance is essential.

Applications

1. Conveyor Systems:
   The KMB UC 208/24 is ideal for conveyor systems used in material handling, particularly in environments where space is limited but reliability and smooth operation are key. Its self-aligning design ensures the bearing remains operational even when slight misalignments occur, making it a reliable choice for conveyor belts in smaller-scale operations.
2. Agricultural Machinery:
   The UC 208/24 is also commonly used in agricultural machinery, such as small tractors, harvesters, and plows, where compact, durable bearings are needed to support light to moderate loads. Its sealed design helps protect against dirt and moisture found in outdoor and field environments, ensuring long-lasting performance.
3. Industrial Equipment:
   This bearing unit is suitable for a range of industrial equipment, such as pumps, small motors, and light-duty machinery. The UC 208/24 offers reliable performance for applications where moderate radial load capacity is required, and its self-aligning function helps to reduce wear due to misalignment.
4. Small Machinery:
   The UC 208/24 is perfect for smaller machines and devices where space constraints are a concern. Its compact design and ability to handle moderate loads make it ideal for use in light-duty machinery, automated systems, and other applications where a reliable bearing solution is needed but with a smaller bore size.
5. Automated Systems:
   The UC 208/24 can be used in automated systems where precision and smooth operation are essential. Its easy installation, self-aligning feature, and sealed protection make it a practical choice for machinery involved in light to medium duty tasks, where alignment and minimal maintenance are important.
6. Textile and Paper Industry:
   In textile machinery and paper mills, the UC 208/24 bearing unit provides reliable support for rollers, conveyors, and other components. Its ability to operate smoothly in dusty, dirty, or humid environments makes it a popular choice in industries where such conditions are common.
