  • Precise 1/2 in bore fits standard shafts accurately
  • Length held to ± .005 in for consistent alignment
  • Pack of three reduces reorder frequency for maintenance teams

Precision bronze sleeve bearing

This Bunting Bearings CB081312 sleeve bearing is a plain cylindrical bushing machined from C93200 cast bronze, also known as SAE 660. It measures 1/2 in bore by 13/16 in outside diameter with an overall length of 1 1/2 in and is supplied in a pack of three. The non-flanged design suits straight-bore housings where a flange would interfere with adjacent components.

Replaces worn inch-series bushings

Use these bearings to renew plain-bearing locations that have developed excessive clearance or scoring on the shaft. The bronze alloy tolerates temperatures from -450 Degrees F to 500 Degrees F, so the upgrade is worthwhile when the original plastic or sintered insert has melted, cracked or worn prematurely in high-heat or cryogenic service. Length tolerance is held to +/- 0.005 in for consistent press fits.

Fits maintenance kits and small-batch rebuilds

The three-piece pack suits mechanics who keep standard inch sizes on hand for hydraulic cylinders, conveyor idlers or agricultural linkages. Buyers needing metric bores, flanged variants, oil-impregnated sintered bronze or corrosion-resistant alloys should look at other product lines.

Questions about this item

What shaft size fits the 1/2 in bore of this Bunting CB081312 sleeve bearing?

The bearing accepts a 1/2 in shaft with an outside diameter of 13/16 in and a length of 1 1/2 in, supplied in a pack of three.

How do I install the non-flanged bronze bearing and what step is often missed?

Press the C93200 cast bronze sleeve into a housing that matches the 13/16 in outside diameter, then verify the +/- 0.005 in length tolerance so the bearing seats fully without binding.

When will the C93200 bronze material need replacement in high-temperature use?

The bearing is rated from -450 to 500 degrees F; inspect for wear or dimensional change if it operates near the 500 degree F limit for extended periods.
