The Bambu Lab P2S XY Belt Tensioner is an OEM replacement for the belt tensioning mechanism in the CoreXY motion system of the Bambu Lab P2S. Correct belt tension is critical: too loose and the belts slip, causing layer shifts; too tight and bearing wear and ringing artifacts increase. This tensioner provides the designed adjustment range to keep XY belts at optimal operating tension.

A worn or broken tensioner makes it impossible to maintain proper belt tension, degrading print quality through increasing dimensional inaccuracy and surface artifacts. Replacing with a genuine Bambu Lab tensioner restores precise belt control for high-speed, high-accuracy printing.
