Bronze sleeve bearing for 1 7/16 in shafts

This Bunting Bearings CB232824 sleeve bearing fits a 1 7/16 in bore and measures 1 3/4 in outside diameter by 3 in overall length. It is manufactured from cast bronze graded C93200 (SAE 660) and supplied new for machinery power-transmission applications. The non-flanged, plain bearing design suits linear or rotary motion where a simple metallic interface is required. Length tolerance is held to +/- .005 in.

Operating range from -450 to 500 degrees F

The bronze material remains functional across a temperature span of -450 Degrees F to 500 Degrees F, allowing use in cryogenic and high-heat environments without thermal degradation. No lubrication system is integrated, so friction and noise depend entirely on the external lubricant chosen and the shaft surface finish. Power draw is not a characteristic of this passive component. The metallic construction avoids the outgassing or softening seen in polymer alternatives at temperature extremes.

California Proposition 65 notice included

The supplier flags that this product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm. No accessories, mounting hardware or software are bundled with the bearing. The absence of a flange means the installer must provide axial location separately. Buyers needing a flanged variant or a different bore size must select another part number.

Questions about this item

How do you install the CB232824 bronze sleeve bearing and what step is often missed?

Press the 1 7/16 in bore onto the shaft to a 3 in depth; the step often missed is verifying the +/- 0.005 in length tolerance before final seating.

What maintenance will the C93200 cast bronze sleeve need later?

The SAE 660 bronze material requires periodic lubrication; inspect for wear and reapply compatible grease at intervals suited to the load and speed.

What limit appears first when the bearing runs continuously at high temperature?

The 500 Degrees F maximum temperature rating is the first limit reached under sustained heat; the -450 Degrees F minimum is not a factor in normal operation.
