This replacement roller assembly is intended for hobbyists who maintain or restore Jr HG chassis models. The bowl-type roller profile limits lateral contact with guard rails and is machined from aluminum to resist wear compared with plain plastic rollers. The ball-race design reduces rotational friction relative to plain bushings and is compatible with common Jr HG roller mounts.
Installation notes: use appropriate rollershaft length and secure each roller with the correct spacer or locknut to preserve alignment. Check clearance against local track features and plastic guards before running. For collectors, the aluminum finish is a visible detail that matches metal accessory sets commonly fitted to display builds.
Material: Aluminum Roller diameter: 11 mm Bearing type: Ball-race Roller style: Bowl-type Compatible chassis: Jr HG
These bowl-type aluminum ball-race rollers provide a durable, low-friction option for maintaining Jr HG chassis models and for display-quality builds.
