Three bronze sleeve bearings cylindrical smooth finish

Bunting Bearings

Bunting Bearings CB121614 sleeve bearing bronze 3/4 in bore 1 in OD 1 3/4 in length PK3

SKU CH-BS9C-VNRVV

Bronze sleeve bearing with 3/4 inch bore, 1 inch outside diameter and 1-3/4 inch length, supplied in a pack of three

  • Bronze construction resists corrosion with C93200 (SAE 660) material grade
  • Wide temperature range suits extreme environments from -450 Degrees F to 500 Degrees F
  • Precise fit ensured by +/- 0.005 in length tolerance
  • Non-flanged design simplifies installation in plain bearing applications
  • Three-piece pack provides ready spares for maintenance or replacement needs

Bronze sleeve bearing for 3/4 in shafts

This Bunting Bearings CB121614 sleeve bearing uses C93200 cast bronze to support a 3/4 in shaft inside a 1 in housing across a 1 3/4 in length. It suits maintenance teams and OEM assemblers who need a plain-metal bearing for moderate-speed rotary or oscillating motion in industrial machinery. The material handles a continuous temperature range from -450 to 500 degrees F.

Pack of three simplifies spares management

Each box delivers three identical bearings so a single order covers multiple shaft positions or provides ready replacements during scheduled overhauls. No lubricant, seals, flanges or mounting hardware are included; the bronze surface is designed to run with external oil or grease supplied by the application. California Proposition 65 notices apply to the alloy.

Press-fit installation requires bore tolerance

The bearing installs by press fit into a housing bore that must be machined to the correct interference for a 1 in outside diameter with a +/- 0.005 in length tolerance. Common issues arise when the housing is oversized, causing spin, or undersized, distorting the bore and reducing running clearance. Proper alignment and cleanliness during assembly prevent premature wear.

Questions about this item

How often will the CB121614 bronze sleeve bearings need to be replaced under normal operating conditions?

The C93200 cast bronze material is designed for long service life with proper lubrication, but replacement intervals depend entirely on load, speed, alignment, and maintenance practices in your specific application.

What is the first performance limit reached when the CB121614 bearings run continuously at high loads?

The maximum operating temperature of 500 degrees Fahrenheit is the primary thermal limit; sustained operation near this temperature will degrade the bronze material and lubricant faster than mechanical wear alone.

How much heat and noise do the CB121614 bearings generate during all-day operation?

As plain sleeve bearings, they operate silently with no moving elements to generate noise; heat generation is a function of friction from shaft speed and load, and the bronze material conducts heat away from the contact surface effectively.
