Design Features of FY 55 TF Bearing

FY 55 TF feature an integrated bearing insert and a flanged housing that allows direct mounting onto vertical or side surfaces for precise shaft positioning. The flanged design ensures secure alignment and stable load distribution, even in compact or space-limited installations. Sealed constructions and durable housing materials enhance protection against contaminants and extend service life in industrial environments.


What Benefits Can FY 55 TF Bearing Provide?

  • Compact and Space-Saving Design: The flanged housing allows direct mounting to equipment frames or walls, making it ideal for installations with limited space.
  • Accurate Shaft Positioning: The flange structure helps maintain precise axial and radial alignment, improving operational stability and reducing vibration.
  • Easy Installation and Secure Mounting: Pre-drilled mounting holes enable quick installation while ensuring firm and reliable fixation.
  • Good Load Support Capability: Flange bearings can handle radial loads and moderate axial loads, suitable for a wide range of light to medium-duty applications.
  • Low Maintenance and Long Service Life: Sealed designs and robust materials protect against dust and contaminants, minimizing maintenance requirements and extending bearing life.


What Can FY 55 TF Bearing Be Used for?

  • Conveyor and Transfer Systems: They support shafts mounted on vertical or side panels, ensuring accurate alignment in compact conveyor layouts.
  • Packaging and Automation Equipment: Widely applied in automated production lines where precise positioning and space efficiency are critical.
  • Food and Beverage Processing Machinery: Used in equipment requiring hygienic designs and stable shaft support, often with stainless steel housings.
  • Material Handling and Light Industrial Machinery: Suitable for guides, rollers, and auxiliary shafts operating under moderate loads.
  • Agricultural and General Machinery: Applied in pumps, fans, and small mechanical systems where reliable, easy-to-mount bearing solutions are required.
