Kyosho BRG417 Shield Bearing (7x14x4) 2pcs  [KY-BRG417]

Shielded ball bearing, 7x14x4, 2pcs

This Kyosho BRG417 pack contains two shielded bearings sized 7x14x4 intended for scale R/C applications. The shields help limit dirt ingress while providing smooth rotation where compact bearings are required. The 7x14x4 marking identifies bore, outer diameter and width dimensions that are commonly used in drivetrain mountings, wheel hubs, and small rotating linkages.

Installation is straightforward but benefits from basic care: press bearings into hubs or carriers squarely using a drift on the outer race to avoid loading the balls, confirm the bore and shaft clearance before final fit, and retain with the original spacers or snap rings from your model. These bearings are supplied as 2pcs per pack to match left and right positions or to keep a spare on hand during maintenance.

For tuning and maintenance, keep the shields clear of grit and avoid forcing lubricants that attract dust into the seal area. Light, RC-specific bearing oil can be applied sparingly to improve longevity and reduce drag. Replacing worn bearings can return imprecise steering or noisy drivetrain components to predictable behaviour without altering geometry or gear ratios.
