  • Cast bronze C93200 resists wear in heavy-load applications
  • Wide -450 °F to 500 °F range suits extreme environments
  • Tight ±0.005 in length tolerance ensures precise fit
  • 1 in bore × 1¼ in OD matches standard inch shafts
  • Pack of three reduces reorder frequency for maintenance teams

Bronze Sleeve Bearing 1 in Bore

The Bunting Bearings CB162012 is a plain bronze sleeve bearing with a 1 in bore and 1 1/4 in outside diameter. It measures 1 1/2 in overall length with a tolerance of +/- .005 in. The C93200 SAE 660 cast bronze construction suits maintenance and repair tasks in industrial machinery and automotive workshops. Supplied as a pack of three for spares or volume fitting.

Operating Range -450 to 500 Degrees F

The bearing operates continuously from -450 Degrees F up to 500 Degrees F without lubrication breakdown. Cast bronze material dissipates heat evenly under load, keeping running temperatures stable during normal use. No cooling fans or forced-air systems are required for the bearing itself. The wide thermal window suits both cryogenic and high-heat environments.

Pack of Three Simplifies Inventory

Each package contains three identical bearings, reducing reorder frequency for maintenance teams. Having matched spares on hand allows immediate replacement during scheduled downtime. The bronze finish resists surface corrosion in storage. No additional software, seals or mounting hardware are included with the pack.

Questions about this item

How do I press-fit the CB162012 bronze sleeve bearing into a 1 1/4 inch housing bore without damaging the 1 inch bore?

Chill the bearing or heat the housing for a slip fit, then press squarely on the outer diameter using a mandrel; stop when the 1 1/2 inch length seats flush and verify the bore stays within the +/- 0.005 inch tolerance.

When should I replace the C93200 cast bronze sleeves in a high-cycle application?

Replace when the 1 inch bore shows measurable wear beyond the original clearance, when the bronze surface scores or flakes, or when operating temperatures approach the 500 degree F limit and lubrication can no longer maintain a film.

What is the first limit reached if the sleeve bearing runs continuously near its 500 degree F maximum temperature?

The lubricant breaks down first, eliminating the hydrodynamic film and causing rapid bronze-on-shaft wear long before the C93200 material itself softens.
