UCF208 40mm Bore Cast Iron Housing Flange Mounted Pillow Block Bearings

UCF208 Flanged Bearing Unit – Rugged, Reliable, and Ready for Heavy-Duty Service

Designed for easy installation and dependable operation in demanding environments, the UCF208 is a popular choice across industrial, agricultural, and material handling sectors.

Key Features:

• Complete Unit – Ready to Install
  The UCF208 arrives fully assembled, lubricated, and sealed. No need to press bearings into housings, calculate fits, or add grease. The 4-bolt flange design allows for quick, secure mounting directly to flat surfaces. Four bolt holes (16mm diameter) accept M14 bolts, providing a strong, vibration-resistant attachment.

• Self-Aligning Feature – Compensates for Misalignment
  The insert bearing’s outer ring has a spherical convex shape that mates with a concave spherical surface inside the housing. This allows the bearing to self-align up to ±2° to ±3° of angular misalignment. If your shaft or mounting plate is not perfectly straight, the bearing adjusts automatically – reducing stress on the shaft, preventing premature wear, and extending bearing life.

• Heavy-duty cast iron enclosure – Durable and long-lasting
  This enclosure is precisely cast from cast iron, featuring excellent strength, shock absorption properties, and resistance to deformation under load. The enclosure has also undergone painting treatment to resist rust and corrosion in regular industrial environments. For harsher conditions (outdoor, exposure to water, contact with chemicals), we offer optional stainless steel or coated enclosures.
• High load capacity and speed performance
  The UCF208 can withstand large radial loads and moderate axial loads. Its maximum rotational speed limit is 3000 to 3600 revolutions per minute, making it suitable for most belt drives, conveyor belt drums, fans and pumps applications. For higher rotational speeds, consider using a different bearing series or cooling options.
