Hirobo HI2500063 3 x 7 x 2 mm Flanged Ball Bearing Pack of 2 Open Type  [HI2500063]

Compact Flanged Bearing Details

The Hirobo HI2500063 flanged ball bearing comes as a pair and is sized 3 x 7 x 2 mm for RC-scale applications. The flange on the outer ring locates the bearing axially in shallow housings where space is limited. Being open type, the unit rolls freely but requires external lubrication to maintain longevity.

For fitting, gently press the flanged outer race into the matching bore or retain it with a thin clip where clearance prevents deeper seating. Inspect shaft and bore dimensions before installation, keep contact surfaces clean, and do not press on the inner race to avoid damaging the raceway. Use a light bearing oil or thin grease to protect against wear when components are exposed to dust.

Correct seating of the 3 x 7 x 2 mm flanged bearing reduces side-to-side play at pivots and linkages, improving mechanical precision and repeatability during fine tuning. Regular inspection and basic upkeep will keep small drivetrains and linkage assemblies running smoothly.
