Three bronze cylindrical sleeve bearings with smooth surfaces

Bunting Bearings

Bunting Bearings CB071212 Sleeve Bearing Bronze 7/16 in Bore 3/4 in OD 1 1/2 in Length PK3

SKU CH-5RHN-1QC49

Bronze sleeve bearing with 7/16 inch bore, 3/4 inch OD and 1-1/2 inch length, supplied in packs of three

  • Bronze construction resists corrosion in harsh environments
  • Operates reliably from -450 °F to 500 °F
  • SAE 660 grade delivers consistent wear performance
  • Pack of three simplifies maintenance inventory
  • Tight ±.005 in length tolerance ensures precise fit

Plain Bronze Sleeve Bearing

This is a plain bronze sleeve bearing made from C93200 cast bronze. Each pack contains three pieces with a 7/16 in bore and 3/4 in outside diameter. The overall length measures 1 1/2 in with a tolerance of +/- 0.005 in. It is a non-flanged design supplied new for general machinery use.

Temperature Range and Fit Constraints

The bearing operates between -450 Degrees F and 500 Degrees F, setting the practical thermal limits for any application. Because the bore and outside diameter are fixed inch dimensions, the bearing only fits shafts and housings that match those exact sizes. No flange means axial location must be provided by other components in the assembly.

Material Grade C93200 (SAE 660)

The cast bronze grade C93200 (SAE 660) determines wear resistance, load capacity and lubrication requirements. Buyers who need a different bronze alloy, a flanged design or metric dimensions cannot use this part. The Prop 65 notice also flags regulated chemicals for compliance checks.

Highlights

  • Bronze construction resists corrosion in harsh environments
  • Operates reliably from -450 °F to 500 °F
  • SAE 660 grade delivers consistent wear performance
  • Pack of three simplifies maintenance inventory
  • Tight ±.005 in length tolerance ensures precise fit

Questions about this item

How do I decide between the three bearings in the pack and buying them individually?

The package contains three identical sleeve bearings, each with a 7/16 in bore, 3/4 in outside diameter and 1 1/2 in length, so one pack covers three mounting points.

What does the 500 °F maximum temperature mean for continuous operation in my equipment?

The cast bronze material grade C93200 is rated for sustained use up to 500 °F and remains functional down to -450 °F, making it suitable for high-heat or cryogenic environments.

How does the SAE 660 bronze grade affect the bearing's load and speed limits in practice?

SAE 660 (C93200) cast bronze provides good wear resistance and conformability for moderate loads and speeds, but specific load or velocity limits depend on lubrication and alignment in your application.
