The Ultimaker Sliding Block Assembly 920 is an original service spare part for the Ultimaker S5 3D printer. Along with the L714 variant, the L920 sliding block assembly covers the longer rod position in the S5's XY motion system. Together, the two lengths ensure that all rod positions in the S5 motion system can be fully serviced with factory-specification sliding blocks, maintaining the printer's dimensional accuracy and print quality over time.

When the S5 shows increased play in the XY system, dimensional inaccuracies, surface artefacts such as ghosting or ringing, or audible noise from the motion system, worn sliding blocks are a likely cause. Replacing the L920 blocks with genuine Ultimaker service parts restores the precision and smooth operation the S5 is designed to deliver.
