Bronze sleeve bearing for light-load motion

The Bunting Bearings CB081210 is a cast-bronze plain bearing supplied in packs of three. It suits shafts that rotate or slide at low speed where a simple, lubricated bronze interface is preferred over rolling-element alternatives.

Steady temperatures from -450 to 500 Degrees F

The C93200 (SAE 660) bronze retains its mechanical properties across the full rated range without the thermal cycling limits that affect polymer bushings. Length tolerance is held to +/- 0.005 in so alignment stays consistent during prolonged operation.

Check shaft diameter and lubrication plan

Verify the mating shaft measures 1/2 in and that the housing can accommodate a 3/4 in outside diameter with 1 1/4 in overall length. The non-flanged design requires axial location by other means, and the material group is metallic so regular lubrication must be provided.

Questions about this item

How much heat can the CB081210 bronze sleeve bearing withstand during continuous operation?

The bearing is rated for a maximum temperature of 500 degrees F and a minimum of -450 degrees F, making it suitable for high-heat industrial environments.

What shaft size is required to install these 1/2 in bore bearings?

These bearings are designed for a 1/2 in bore diameter, so a matching 1/2 in shaft is needed for proper fit and function.

Will the C93200 bronze material work with older steel shafts in existing machinery?

Yes, the SAE 660 (C93200) cast bronze material is compatible with standard steel shafts commonly found in older equipment.
