Hirobo HI2500033 Flanged Ball Bearing Set 2 pcs 6 x 12 x 4 mm  [HI2500033]

Flange-located bearing for axial control in tiny assemblies

Offered as a set of two, these 6 x 12 x 4 mm flanged ball bearings suit small helicopter components and similar miniature model mechanisms. The flange on the outer race acts as an integrated locating surface to limit axial movement and keep the bearing seated in shallow housings.

They work well where a compact axial stop is needed, for instance in small rotor hubs, compact gearbox points, or idler positions where the flange removes the requirement for extra retaining parts. Always check the mounting face is flat and free of burrs so the flange seats fully before tightening.

• Condition: Supplied as 2 pcs for paired replacement or multi-point installations.
• Installation note: Install with the flange against the locating face; apply steady pressure and avoid cocking the bearing to prevent race damage.
• Maintenance tip: Keep surrounding areas clean and use a light bearing lubricant suitable for miniature bearings when necessary.
