Bunting Bearings EP121412 bronze sleeve bearing 3/4 in bore 3/4 in length pack of 3

Bronze sleeve bearing for 3/4 inch shafts

The Bunting Bearings EP121412 is a plain bronze sleeve bearing designed for 3/4 inch bore shafts. It measures 3/4 inch in length with a 7/8 inch outside diameter. The sintered bronze construction contains embedded SAE 30 oil for self-lubricating operation. Supplied as a pack of three pieces for maintenance or production use.

Suited for light-duty inch-size applications

This bearing suits machinery requiring a simple 3/4 inch plain bearing within a temperature range of 10 to 220 degrees F. It is not intended for flanged mounting, high-speed precision spindles, or environments needing sealed or re-lubricatable designs. Buyers needing a flanged bearing, a different bore size, or a higher load capacity should look at alternative bearing types.

Press-fit installation with tight length tolerance

Installation is a standard press fit into a prepared housing bore. The length tolerance is held to +/- 0.005 inch, so the housing depth must be controlled to match. The most common issue is an oversized housing bore causing the bearing to rotate or walk out under load. Ensure the housing diameter matches the 7/8 inch outside diameter for proper retention.
