3. Detailed Mounting Dimensions
For the UCFC 208 model, the standard reference mounting dimensions according to technical catalogues include:
4. Construction and Key Features
The UCFC 208 FK pillow block bearing consists of two main components: the FC208 bearing housing and the UC208 insert bearing. The housing is manufactured from cast iron, providing high structural rigidity and good load-bearing capacity under industrial operating conditions.
The UC208 insert bearing features a deep-groove ball bearing design, an extended inner ring, and a two-set-screw locking mechanism. This configuration securely fixes the bearing onto the shaft and helps prevent relative slippage during power transmission.
In addition, the bearing is equipped with sealing arrangements on both sides to prevent dust and contaminants from entering while retaining the lubricating grease inside. Depending on the configuration, a grease nipple may also be provided to facilitate periodic relubrication and maintenance.
5. Applications of UCFC 208 FK Pillow Block Bearing
Thanks to its four-bolt round flange design, the UCFC 208 FK bearing unit can be installed on various types of machine structures. Typical applications include:
- Industrial conveyor systems and material handling equipment.
- Agricultural product processing, food processing, and animal feed machinery.
- Crushers, mixers, and material processing equipment.
- Industrial fans and ventilation systems.
- Packaging machinery and mechanical power transmission equipment.
- Rotating shaft assemblies in industrial manufacturing plants.
6. Selection and Operating Considerations
When selecting the UCFC 208 FK pillow block bearing, it is essential to confirm the shaft diameter of 40 mm and check the flange dimensions, mounting bolt hole positions, and actual operating load conditions.
During installation, ensure that the mounting surface is flat, the shaft is properly aligned, and the set screws are tightened to the recommended torque.
Regular inspections of lubrication conditions, vibration levels, operating temperature, and seal integrity are also necessary to maintain equipment reliability and extend service life.
The UCFC 208 FK pillow block bearing is a suitable bearing solution for various industrial power transmission systems using 40 mm diameter shafts. With its robust flange housing, UC208 insert bearing, and convenient maintenance features, the product helps improve operational stability, equipment reliability, and overall machinery efficiency.
