  • Fixed expansion design maintains precise shaft alignment
  • NLGI #2 equivalent grease lubricates from -40 to 250 degrees F

Industrial Bearing for Power Transmission

This new TRITAN HCFU204-12 unit is a 4 bolt flange bearing designed for radial ball applications in power transmission systems. It suits maintenance teams and equipment builders who need a fixed housing with a 3/4 in cylindrical bore. The cast iron housing and alloy steel insert handle radial loads in industrial machinery.

Temperature Range Defines Operating Envelope

The bearing operates reliably between -40 degrees F and 250 degrees F using NLGI #2 equivalent lubricant. Double seals protect the rolling elements from contamination in harsh environments. Performance outside this thermal window is not supported by the design.

3/4 Inch Bore Determines Shaft Compatibility

The cylindrical bore diameter of 3/4 in is the critical dimension for shaft fit. The square housing measures 3 3/8 in overall with mount holes on 2 1/2 in centers. Buyers needing a different bore size or expansion type must select another part.

Questions about this item

Should I choose the HCFU204-12 with a 3/4 inch bore or look for a different bore size?

The HCFU204-12 has a cylindrical bore of 3/4 in. Select this version when your shaft matches that diameter; otherwise choose a bearing with the bore your shaft requires.

What does the 250 degrees F maximum temperature mean for daily operation?

The bearing is rated to 250 °F maximum and -40 °F minimum. In a real machine the lubricant (NLGI #2 equivalent) and double-sealed radial ball insert will stay within spec as long as the housing temperature does not exceed 250 °F.

How does the 4-bolt square flange mounting pattern limit installation options?

The square housing has four mount holes on a 2 1/2 in center-to-center height and an overall 3 3/8 in square footprint. You can only bolt it to a flat surface that matches that hole pattern and clearance.
