Introducing the FK UCFC 211 Bearing Unit – A Secure Installation Solution for Stable Operation
In industrial drive systems, a bearing unit is essential for supporting the shaft, reducing friction and ensuring stable machinery operation. The round flanged UCFC 211 unit from FK is a popular choice because of its durable design, easy installation and suitability for diverse working environments.
1. Product overview
The FK UCFC 211 is a round flanged cartridge unit designed with four bolt holes for secure mounting on a machine surface. It is a complete assembly combining an FC211 housing and a self-aligning UC211 insert bearing, making installation and replacement convenient.
With a standard shaft diameter of 55 mm, the UCFC 211 suits many medium- to heavy-load drive systems, especially in manufacturing, processing and mechanical engineering.
2. Detailed construction
The FK UCFC 211 bearing unit consists of two main components:
Housing (FC211 Housing)
Made from high-quality cast iron with good rigidity and load-bearing capacity. The round flange distributes forces evenly, reduces vibration and improves operating stability. Precisely machined bolt holes ensure concentricity and easy installation.
UC211 insert bearing
A self-aligning ball bearing that compensates for minor misalignment between the shaft and housing during operation. Set screws secure the bearing to the shaft, maintaining its position and limiting shaft creep.
The product also includes:
- Seals on both sides that protect the bearing against dust and contaminants
- A grease fitting for periodic maintenance and longer equipment life
3. Basic specifications
According to the FK catalog, the UCFC 211 bearing unit has the following typical specifications:
- Shaft diameter (d): 55 mm
- Bolt-hole center distance (p): 150 mm
- Flange outside diameter (a): 185 mm
- Center height (e): 106.1 mm
- Bearing width (B): 55.6 mm
- Bolt size: M16
These dimensions make the product compatible with many types of equipment and commonly used installation standards.
4. Key advantages
Fast, flexible installation
The round four-hole flange can be secured firmly to different surfaces, including machine frames, vertical walls and support bases.
Good self-aligning capability
The self-aligning UC211 insert bearing compensates for minor shaft misalignment, reduces localized loads and limits wear.
High durability and good load capacity
A robust cast-iron housing combined with a quality bearing helps the unit operate reliably under load and vibration.
Easy maintenance
A convenient grease fitting allows rapid maintenance without disassembling the entire unit.
Cost effectiveness
Compared with premium brands, FK provides a cost-optimized solution while maintaining performance and reliability.
5. Practical applications
The FK UCFC 211 bearing unit is widely used in:
- Conveyor systems in manufacturing plants
- Food-processing and packaging machines
- Agricultural machinery such as rice mills and feed mixers
- Industrial fans and ventilation systems
- General mechanical drive equipment
Its flexibility and high durability allow the product to perform well in both continuous operation and dusty environments.
6. Usage notes
To ensure efficient operation and extend the life of the FK UCFC 211 bearing unit:
- Install it concentrically with the shaft and avoid excessive misalignment
- Tighten bolts and set screws using the correct procedure
- Lubricate periodically according to working conditions
- Monitor vibration and temperature during operation
7. Conclusion
The FK UCFC 211 bearing unit is a reliable solution for drive systems requiring stable operation, easy installation and reasonable cost. Its robust design, good self-aligning capability and standard dimensions help optimize operating performance and reduce business maintenance costs.
