Bunting Bearings CB141612 Bronze Sleeve Bearing 7/8 in Bore PK3

Bronze Sleeve Bearing Specifications

The Bunting Bearings CB141612 is a plain sleeve bearing machined from cast bronze alloy C93200, also referenced as SAE 660. It is supplied in a pack of three units for maintenance or assembly tasks. Each bearing has a 7/8 inch bore, a 1 inch outside diameter and an overall length of 1 1/2 inches with a length tolerance of +/- 0.005 inches. The non-flanged design suits straight-bore housings in industrial machinery.

Temperature Range and Load Capacity

The bronze material provides a continuous operating window from -450 degrees F to 500 degrees F, giving wide headroom for cryogenic equipment and high-heat environments. Within this range the bearing handles moderate radial loads and oscillating motion typical of pivot points and linkage arms. At sustained speeds or heavy shock loads the material will reach its PV limit, so designers must verify pressure-velocity ratings for the specific application.

Inch Dimensional Standard and Compliance

All critical dimensions follow the inch measurement system, so the bearing fits legacy imperial shafts and housings without metric conversion. The alloy contains substances listed under California Proposition 65 as known to cause cancer and reproductive harm, requiring appropriate handling and warning labels in affected jurisdictions. Buyers needing flanged retention, metric bores or self-lubricating composites must select a different bearing style.
