What this bearing is and who needs it

The Koyo BH-912 is a drawn-cup needle roller bearing with a 9/16 in bore and 13/16 in outside diameter. It uses a full complement of rollers in alloy steel rings and ships new with oil lubrication. Maintenance teams and machine builders use it where a compact radial bearing is required.

What to verify before ordering

Confirm the shaft diameter matches the 9/16 in bore and that the housing can accept the 13/16 in outside diameter. The bearing is open, so the assembly must supply its own sealing arrangement. Check that the IR-612 inner ring is available if the shaft surface does not meet the required hardness and finish.

Behaviour under sustained load

The bearing is rated for a maximum speed of 7,100 RPM and operates between -22 and 248 degrees F. Oil lubrication must be maintained continuously at speed; the open design does not retain grease. Plan for relubrication intervals that suit the actual running temperature and contamination level.
