Bronze sleeve bearing for light shafts

This Bunting Bearings sleeve bearing is a plain, self-lubricating bronze bush designed for 3/8 in shafts. It suits maintenance teams and machine shops that need a simple, metallic bearing for low-speed or oscillating motion.

Press into a housing and add SAE 30 oil

The non-flanged, 1/2 in outside diameter presses into a matching bore without a flange register. Embedded lubricant and a 1 in overall length reduce the need for external oil lines, freeing space in tight assemblies.

Steady from 10 to 220 Degrees F

Sintered bronze construction maintains clearance within +/- 0.005 in across the rated temperature span. The material resists galling under continuous load, avoiding the seizure risk that can appear in short-burst testing.

Questions about this item

How long can the bearing run continuously at 220 °F before the embedded SAE 30 oil film degrades?

The bearing is rated for a maximum temperature of 220 °F and uses self-lubricating embedded SAE 30 oil, but continuous runtime at that limit depends on load and speed conditions.

What noise or heat increase should I expect when the sleeve operates all day under load?

Sintered bronze with embedded oil runs quietly; heat rise stays within the 10 °F to 220 °F range if the shaft speed and radial load remain within design limits.

What shaft diameter and housing bore must I already have to install these 3/8 in bore by 1/2 in OD bearings?

You need a 3/8 in shaft and a 1/2 in housing bore; the bearing length is 1 in with a ±0.005 in tolerance.
