TRITAN SBF204-12G Flange Bearing 3/4" Bore 4-Bolt

This is a new TRITAN SBF204-12G four-bolt flange bearing with a 3/4 inch bore. The housing is made of cast iron and the bearing insert uses alloy steel with a radial ball design. It comes double sealed and pre-lubricated with an NLGI #2 equivalent grease. The unit is transparent in colour and operates between -40 and 120 degrees Celsius.

Suitable for maintenance teams replacing fixed

This bearing suits technicians who need a direct replacement for a square four-bolt flange unit with a 19 mm cylindrical bore and a 63.9 mm mount hole centre-to-centre height. It is not for buyers who require an expansion type housing or a different bore diameter. Collectors looking for display pieces without technical specifications should look elsewhere.

Verify bore diameter and mounting pattern before

Confirm that your shaft measures exactly 3/4 inch or 19 mm for a proper cylindrical fit. Check that the existing mounting surface accepts a square flange with four holes on an 85.7 mm overall height and length pattern. Ensure the operating temperature range of -40 to 120 degrees Celsius matches your application environment.

Questions about this item

What size mounting bolts and shaft does this 19 mm bore flange bearing require?

The housing has four mount holes on a 63.9 mm centre-to-centre pattern and accepts a 19 mm cylindrical shaft.

Will the double-sealed insert survive next to older cast-iron housings that run hotter than 120 °C?

The bearing is rated to 120 °C maximum; temperatures above that exceed its lubricant limit.

How can I confirm the SB204-12G insert is seated correctly after bolting the 85.7 mm square housing down?

Rotate the shaft by hand — it should turn smoothly with no binding or excessive play.
