Product Identity

This new Tritan UCFL204-20MM unit is a two-bolt flange bearing with a rhombus housing. It suits maintenance teams and hobbyists who collect power-transmission components. The cast-iron housing holds a radial ball insert made from alloy steel. Double seals protect the NLGI #2 equivalent lubricant across a wide temperature range.

Upgrade Context

It replaces a worn or seized fixed-expansion bearing on light-duty shafts. The jump is worth it when the old unit shows excess play, heat or seal failure. Collectors add it when the specific bore and housing geometry complete a series.

Fit Check

Verify the shaft diameter matches the 20 mm cylindrical bore. Confirm the mounting pattern fits the 33.3 mm by 60.3 mm footprint with two holes. Ensure the operating environment stays between -40 and 120 degrees C. Check that the 112.7 mm overall height clears adjacent parts.

Questions about this item

What are the exact mounting-hole spacing and overall dimensions for the rhombus housing?

The rhombus housing has two mount holes, an overall height of 112.7 mm, overall length of 33.3 mm and overall width of 60.3 mm.

How is the UC204-20MM insert secured to the shaft during installation?

The cylindrical 20 mm bore uses a set-screw locking collar on the inner ring; the common mistake is tightening the screws before the shaft is fully seated and aligned.

When should the double-sealed radial ball insert be replaced given the lubricant and temperature limits?

Replace the UC204-20MM insert if the NLGI #2 equivalent grease degrades from sustained operation near 120 °C or if contamination breaches the seals.
