Tritan UCF209-45MM flange bearing

The Tritan UCF209-45MM is a square four-bolt flange bearing with a 45 mm cylindrical bore. It arrives new as a complete unit that includes the UC209-45MM radial ball insert. The cast iron housing and alloy steel insert suit industrial machinery and power-transmission builds.

Double-sealed insert handles continuous operation

Double seals retain the NLGI #2 equivalent grease while excluding contaminants during sustained running. The fixed expansion type keeps the shaft location stable under constant radial load. Operating range spans -40 °C to 120 °C without relubrication intervals specified.

Cast iron housing bolts directly to flat surfaces

Four mounting holes on a 105.1 mm centre-to-centre square pattern accept standard bolts for rigid attachment. Overall height and length are both 137.3 mm, giving a compact footprint for tight frames. Blue finish provides visible corrosion resistance in workshop environments.

Questions about this item

How hot does the cast-iron housing get when the bearing runs continuously at its 120 °C limit?

The housing is rated for a maximum operating temperature of 120 °C and a minimum of -40 °C, with NLGI #2 equivalent lubricant suited for that range.

What shaft size and mounting hardware are needed to install the UC209-45MM insert?

The bearing accepts a 45 mm cylindrical shaft and requires four bolts aligned to the 105.1 mm centre-to-centre square pattern.

Will the 137.3 mm square footprint match the bolt pattern on my legacy UC209 pillow-block?

This flange uses a 137.3 mm square housing with four holes on a 105.1 mm centre pattern; verify your old base matches those dimensions before swapping.
