Bronze sleeve bearing for heavy-duty shafts

The CB324016 is a plain bronze sleeve bearing designed for rotating shafts that need a 2 in bore and 2 1/2 in outside diameter. Cast from C93200 alloy (SAE 660), it suits industrial machinery, agricultural equipment and other power-transmission builds where a non-flanged, inch-dimension bearing is specified. Its 2 in overall length provides a broad load-bearing surface for steady radial loads.

Thermal range and friction characteristics

The bearing operates continuously from -450 Degrees F up to 500 Degrees F, covering cryogenic to high-heat environments without lubricant breakdown. Bronze-on-steel contact gives predictable friction and quiet running when properly lubricated, and the material’s inherent wear resistance limits power loss from surface degradation over long duty cycles.

Dimensional control and compliance note

A length tolerance of +/- 0.005 in ensures consistent press-fit alignment and reduces assembly scrap. The part carries California Proposition 65 warnings for chemicals linked to cancer and reproductive harm, so handlers should follow standard industrial hygiene practices. No flange, seals or lubrication fittings are included; the bearing is supplied as a single bronze sleeve ready for custom integration.

Questions about this item

How do I install this 2 in bore sleeve bearing and what step is often done wrong?

Press the bearing squarely into the housing using an arbor press or soft mallet; the step people get wrong is cocking it during entry, which binds the 2 1/2 in OD and ruins the +/- 0.005 in length tolerance.

What maintenance or replacement will this C93200 bronze sleeve bearing need later?

Plan periodic re-lubrication through a grease groove or hole; replace the bearing once the 2 in bore wears beyond the running clearance required by the shaft.

What limit appears first under sustained heavy load on this cast bronze bearing?

The PV limit of the SAE 660 material is reached first, causing accelerated wear before the 500 Degrees F maximum temperature becomes a factor.
