  • Bronze construction resists wear in heavy-duty applications
  • Cast C93200 alloy handles temperatures from -450 °F to 500 °F
  • Non-flanged sleeve design fits 1 3/4 in bore and 2 in outside diameter
  • Precision length tolerance of ±0.005 in ensures consistent alignment
  • SAE 660 grade material meets industry standards for plain bearings

Bronze sleeve bearing for 1 3/4 inch shafts

This cast bronze sleeve bearing fits a 1 3/4 inch bore and measures 2 inches in outside diameter and overall length. It suits machinery requiring a non-flanged plain bearing in inch dimensions. The C93200 (SAE 660) bronze material provides wear resistance for general power transmission applications.

Operating range from -450 to 500 degrees F

The bearing tolerates extreme temperatures from -450 to 500 degrees F without structural change. Bronze construction runs without active cooling and produces no electrical noise. Length tolerance is held to +/- 0.005 inches for consistent fit in high-temperature or cryogenic environments.

Ships free on orders over 75 dollars

Questions about this item

How do I press the CB283216 into its housing without distorting the 2 in outside diameter?

Freeze the bearing or heat the housing to achieve a light interference fit, then press evenly on the outer ring using a sleeve that contacts the full 2 in face; hammering one side will ovalise the bore and ruin the +/- .005 in length tolerance.

When should I plan to replace this C93200 bronze sleeve under normal lubrication?

Replace when the bore wear exceeds the original clearance or when the bronze surface shows scoring that cannot be polished out; the C93200 alloy has no embedded lubricant, so oil-film loss is the first sign that the bearing has reached its service limit.

What temperature limit will I hit first if the shaft runs continuously at high speed?

The 500 Degrees F maximum operating temperature is the first hard limit; sustained heat above that degrades the bronze structure and any lubricant, while the -450 Degrees F minimum only applies to cryogenic starts.
