Upgrade motion systems with precision flanged bearings designed for 3D printers, CNC, and robotics. The integrated flange simplifies alignment and retention in plates and printed parts, delivering smooth, repeatable movement for axes, idlers, and filament guides.

  • Common sizes available: F688ZZ, F684ZZ, F625ZZ, F624ZZ, F623ZZ, F604ZZ and more.
  • Double-shielded (ZZ): Metal shields help keep dust and debris out while maintaining low friction.
  • ABEC-5 precision: Reliable tolerances suitable for high-accuracy motion in FDM printers.
  • Hardened steel races/balls: Durable construction for long service life.
  • Easy alignment: Flange supports accurate seating in mounts and prevents walk-out.

Ideal applications

  • Idler pulleys, filament guides, and belt tensioners.
  • Linear motion carriages and custom jigs/fixtures.
  • Robotics and compact mechanisms needing positive axial location.

Buying tips: Match the inner diameter (ID) to your shaft/bolt size, check outer diameter (OD) and width for your housing, and select ZZ shields for low maintenance in open-frame printers. If you need a specific size not listed, choose “more” and contact support for availability.
