Bunting Bearings CB283212 Bronze Sleeve Bearing 1 3/4 in Bore

SKU CH-RD2Z-K2ARW

Bronze sleeve bearing with a 1 3/4 in bore and 2 in outside diameter, cast from C93200 alloy for temperatures from -450 to 500 °F

  • Bronze construction resists corrosion and wear with C93200 alloy
  • Operates reliably from -450 °F to 500 °F extreme temperatures
  • Precision 1 3/4 inch bore fits shafts with ±0.005 inch tolerance
  • 1 1/2 inch length supports loads in compact machine spaces
  • Non-flanged sleeve design simplifies installation in existing housings

Application fit

This bronze sleeve bearing suits machinery that needs a plain bearing with a 1 3/4 in bore and 2 in outside diameter. The 1 1/2 in overall length fits standard housings where a non-flanged design is specified. It is not for applications requiring a flanged bearing or a different bore size.

Temperature envelope

Cast bronze construction allows continuous operation from -450 Degrees F up to 500 Degrees F. The material grade C93200 (SAE 660) maintains dimensional stability across this range. It is not for environments that exceed these limits or demand a different alloy.

Critical spec

The bore diameter of 1 3/4 in and outside diameter of 2 in are the decisive dimensions for shaft and housing fit. Length tolerance is held to +/- 0.005 in. If your design calls for a different bore, outside diameter or tighter length tolerance, this part will not work.

Questions about this item

How do I pick the right bore size for my shaft?

This sleeve bearing has a 1 3/4 in bore and 2 in outside diameter, so it fits a shaft of that exact diameter.

What does the 500 Degrees F rating mean for daily use?

The cast bronze material handles continuous heat up to 500 Degrees F and stays functional down to -450 Degrees F.

How does the C93200 (SAE 660) grade affect load limits?

C93200 bronze is a standard bearing alloy rated for moderate speeds and heavy loads in inch-dimension machinery.
