This ball bearing set is specified for use with the Team XRAY NT1 chassis and supplied under 3Racing model BS-XN1/V1. It is an RC-scale replacement part intended to fit the drivetrain and wheel mounting points used on the NT1 platform.
The set's role is technical: reduce rolling resistance at rotating assemblies and support consistent alignment of shafts and hubs. When replacing bearings on an NT1, verify seating dimensions and bearing orientation, clean mating bores, and inspect for wear before reassembly.
Installation notes: press bearings evenly into hubs and carriers until fully seated, avoid forcing at an angle, and check clearance at diffs and wheel hexes after installation. For maintenance, remove contaminants, inspect races for pitting, and replace bearings that show play or rough rotation.
This bearing set is presented as a direct replacement option for NT1 owners who need to service drivetrain or wheel assemblies, allowing straightforward swaps when bearings reach end of service life.
