KMB Bearing UC 207/20

The KMB Bearing UC 207/20 is a self-aligning pillow block bearing designed to provide reliable performance in a wide range of industrial and agricultural applications. This bearing unit is particularly well-suited for environments where misalignment is a concern, as it features a self-aligning ball bearing that can accommodate slight angular misalignments between the shaft and housing. Its robust design, combined with a 20mm bore diameter, makes it an ideal choice for smaller machinery and equipment requiring stable performance with moderate radial loads.

Design and Features

1. Self-Aligning Ball Bearing:
   The UC 207/20 incorporates a self-aligning ball bearing that allows it to compensate for minor shaft misalignments. This feature is especially important in systems where the shaft may experience angular displacement or slight deviations from its optimal position. By reducing the stress caused by misalignment, the bearing extends its lifespan and helps prevent premature wear or failure.
2. Pillow Block Housing:
   The bearing unit comes with a pillow block housing that is made from durable cast iron or steel, offering excellent protection and support for the internal bearing components. The housing helps to reduce vibration and maintain stability in the system, even under heavy-duty operating conditions. The pillow block design also facilitates easy mounting, ensuring the bearing unit stays securely in place throughout its service life.
3. Sealed Design for Protection:
   The UC 207/20 is equipped with sealed bearings on both sides. These seals protect the internal ball bearings from dirt, dust, moisture, and other contaminants, ensuring that the bearing operates smoothly in harsh or dirty environments. The sealed design also reduces the need for regular lubrication, making it a low-maintenance solution that extends the bearing’s service life.
4. Set Screw Mounting:
   The UC 207/20 features a set screw mounting system, allowing for quick and secure installation onto a shaft. The set screw ensures that the bearing stays firmly in place, preventing rotation or movement during operation. This simple and efficient mounting method reduces installation time and effort, helping to minimize downtime during machinery setup or maintenance.
5. Compact Design:
   With a 20mm bore diameter, the UC 207/20 is designed to be compact, making it an ideal choice for applications where space is limited. Despite its smaller size, the bearing unit is engineered to handle moderate radial loads, making it suitable for a wide variety of light-duty industrial and agricultural machinery.
6. High Load Capacity:
   The UC 207/20 is built to handle moderate radial loads, making it suitable for use in smaller machinery and equipment that experience light to moderate forces. Its robust construction and self-aligning design ensure that it can deliver consistent performance under normal operating conditions.
7. Durable Construction:
   The housing is made from high-quality cast iron, offering durability and resistance to wear, corrosion, and impact. This construction allows the UC 207/20 to withstand the rigors of everyday use in both industrial and agricultural environments, providing long-lasting reliability even in challenging conditions.
8. Low Maintenance:
   The sealed ball bearings and self-aligning features of the UC 207/20 help to reduce the need for frequent maintenance. The seals keep contaminants out and retain lubrication, minimizing wear and tear and reducing the frequency of lubrication maintenance. This makes it a cost-effective choice for systems where access for regular maintenance may be limited.

1. Conveyor Systems:
   The KMB UC 207/20 is commonly used in conveyor systems where it provides support for rollers, pulleys, or other moving components. Its self-aligning properties are particularly beneficial in conveyor systems where slight shaft misalignments or vibrations may occur during operation. The sealed bearings also protect against contaminants found in material handling environments.
2. Agricultural Machinery:
   The UC 207/20 is ideal for use in agricultural machinery such as small tractors, harvesters, and plows. The bearing unit’s ability to handle moderate radial loads, combined with its sealed protection against dirt and moisture, makes it a durable solution for outdoor agricultural applications.
3. Industrial Equipment:
   The UC 207/20 is suitable for use in industrial equipment such as small pumps, light-duty motors, and other machinery that requires reliable bearing support for moderate loads. Its self-aligning design ensures smooth operation even in situations where the shaft may be misaligned due to installation errors or operational wear.
4. Automated Systems:
   The UC 207/20 is often used in automated systems where precision and reliable motion are required. The compact design and easy installation of the bearing unit make it ideal for light-duty automated conveyors, sorting systems, and other automated machinery.
5. Textile and Paper Industry:
   In textile and paper mills, where machinery is often exposed to dust, fibers, and other contaminants, the UC 207/20 provides long-lasting support for rollers, shafts, and other components. Its sealed design ensures reliable operation in these harsh environments, helping to reduce downtime and maintenance costs.
6. Small Equipment:
   The UC 207/20 is commonly found in small equipment and machinery where space constraints are a concern. Its compact design and ability to handle moderate radial loads make it a great fit for a variety of light-duty applications in different industries.
