Sintered bronze sleeve bearing for light-duty shafts

The Bunting EP121620 is a plain bronze sleeve bearing with a 3/4 in bore and 1 1/4 in overall length. It uses sintered bronze material impregnated with SAE 30 oil for self-lubricating operation. The unit tolerates temperatures from 10 to 220 degrees F and suits inch-based machinery.

Suits low-speed shafts needing embedded lubrication

This bearing fits applications where a non-flanged, self-lubricating bronze sleeve is specified for the given bore and length. It is not for buyers who need a flanged design, a different bore size, or a bearing rated for temperatures beyond the stated range. It also does not suit environments requiring sealed or externally lubricated units.

Press-fits into a 1 in housing bore to free

The 1 in outside diameter presses into a matching housing bore, securing the sleeve without a flange. Embedded SAE 30 oil eliminates the need for an external lubrication system, simplifying maintenance on compatible shafts. Length tolerance is held to +/- 0.005 in for consistent alignment.

Questions about this item

What shaft diameter must I already have for the 3/4 in bore to fit?

A shaft measuring exactly 3/4 in is required for the bore to seat correctly.

Will the sintered bronze material and SAE 30 oil lubrication tolerate the 10 to 220 Degrees F range of my existing equipment?

Yes, the bearing is rated for continuous operation from 10 Degrees F up to 220 Degrees F.

How can I confirm the embedded lubrication is working after installation?

The shaft should rotate freely without added oil and show no signs of overheating within the rated temperature window.
