8mm ID Bearing to 5mm Hex Shaft Adapter

$0.00 SGD
A flanged insert that runs a REV 5mm hex shaft in a standard 8mm ID ball bearing.

The 4mm body fills the bore of an 8mm ID bearing like the MF148ZZ, and a thin 10mm flange stops it from sliding through. The hex bore keys the inner race to the shaft.

Standard 8mm bearings cost little and come in plenty of sizes, so you can stop hunting for 5mm hex bearings. Drop it into my 15x15 Bearing Plate for a bolt-on shaft support.

What's included:

  • Editable STEP file
  • The 3MF file, ready to slice and print.

Specs:

  • Body: 7.76mm OD x 4mm long (press fit in an 8mm bore)
  • Flange: 10mm OD x 0.4mm
  • Bore: 5mm hex
  • Fits: 8mm ID bearings (MF148ZZ 8x14x4, 688ZZ 8x16x5, goBILDA 1611 series round bore)
  • Shaft: REV 5mm hex

3D Printing Tips

If the design includes 3D printed parts, I highly recommend you print the part out of PCTG. It has some of the highest impact resistance and non-catastrophic breaking for robot parts.

  • If you're looking for a brand, 3D-Fuel is pretty solid in the Americas
  • Azure is better in the EU

For Mechanical/structural parts, I recommend: 

  • 0.6mm Nozzles over 0.4mm. Wider nozzles produce stronger prints in shorter periods of time over thinner nozzles. 
  • Minimum 4 walls. 
  • 30-40% gyroid infill
