Hirobo HI2500117 Ball Bearing 2 x 5 x 2.5 mm Replacement Pack  [HI2500117]

Details of the HI2500117 Bearing

This HI2500117 item is an RC-scale ball bearing sold as a small spare in a pack of 2 pcs and recorded under part code #52ZZ. It is intended for replacing worn bearings in small rotating assemblies where compact dimensions are a requirement.

In service these bearings support rotating shafts and reduce friction between mating parts in rotor linkages and small transmission shafts. Replacing a single worn bearing with an identical unit will often restore smooth rotation and help to eliminate vibration from looseness or rough race surfaces.

Fitting notes: check shaft diameter and the intended fit before pressing the bearing into a housing, confirm the bearing is seated square and inspect for endplay and radial runout after installation. Avoid forcing a bearing onto a distorted or scored shaft without proper preparation and check surrounding parts for wear that might limit bearing life.

Compatibility: listed for Hirobo helicopter general parts and intended for use where a 2 x 5 x 2.5 mm bearing identified by HI2500117 or #52ZZ is required.
