SKU CH-DHBR-90V4T

Bronze sleeve bearing, 5/16 in bore, 1/2 in OD, 1 in length, self-lubricating with SAE 30 oil, pack of three

  • Self-lubricating bronze reduces maintenance needs
  • Embedded SAE 30 oil enables smooth operation
  • Operates reliably from 10 to 220 degrees F
  • Precision bore with +/- .005 in length tolerance
  • Pack of three simplifies inventory management

Bronze Sleeve Bearing Pack

The Bunting Bearings EP050816 is a pack of three sintered bronze sleeve bearings designed for plain-bearing applications in machinery. Each unit has a 5/16 in bore and a 1/2 in outside diameter with an overall length of 1 in. The self-lubricating material uses SAE 30 oil embedded in the bronze matrix to reduce maintenance intervals.

Upgrade From Unlubricated Bushings

These bearings replace plain bushings that require external grease lines or frequent manual lubrication. The jump is worth it when equipment operates in vacuum environments or between 10 Degrees F and 220 Degrees F where consistent lubrication is difficult to maintain. The embedded oil supply eliminates the need for separate lubrication systems in these conditions.

Capacity And Headroom

The sintered bronze construction handles moderate radial loads at low to moderate speeds within the stated temperature range. Length tolerance is held to +/- 0.005 in for consistent fit in housings. The non-flanged design limits axial location, so the bearing runs out when thrust loads or precise axial positioning are required.

Questions about this item

What bore and outside diameter does the EP050816 sleeve bearing need to fit?

The bearing has a 5/16 in bore and a 1/2 in outside diameter, so the shaft must be 5/16 in and the housing bore 1/2 in.

How is this self-lubricating bronze bearing installed, and what step is often missed?

Press the 1 in long bearing into the housing bore; the step often missed is ensuring the SAE 30 oil embedded in the sintered bronze is not flushed out with solvents before assembly.

What maintenance or replacement will the EP050816 bearing need over time?

The embedded SAE 30 oil provides self-lubrication within the 10 to 220 °F range; if the bearing wears beyond the +/- 0.005 in length tolerance or the oil is depleted, replace the bearing.
