Bunting Bearings CB081216 Bronze Sleeve Bearing 1/2 in Bore 3/4 in OD 2 in Length Pack of 3

Industrial Bronze Bearing Pack

This three-pack supplies 1/2 inch bore sleeve bearings machined from C93200 cast bronze for power transmission assemblies. The non-flanged design suits straight bore housings in machinery and automotive tooling. Each piece measures 3/4 inch outside diameter by 2 inches overall length with a +/- .005 inch length tolerance. The bronze colour identifies the alloy at a glance.

Temperature Range and Load Headroom

Cast bronze construction withstands continuous operation from -450 to 500 degrees F without lubricant breakdown. The material grade SAE 660 provides consistent wear resistance under moderate radial loads in conveyors, pivots and guide rails. At sustained high temperatures near the upper limit, clearances should be checked more frequently. Extreme cryogenic cycles may reduce dimensional stability over time.

Machined Finish and Mounting Implications

Precision boring yields a smooth bore surface that reduces initial run-in wear on shafts. The tight length tolerance allows predictable stack-up in multi-bearing housings without shims. Absence of a flange means axial location must be provided by shoulders, snap rings or housing steps. Bronze surfaces accept oil or grease grooves if the application demands supplemental lubrication.
