The Ultimaker Sliding Block Pack for S5, S7 and S8 is an OEM spare parts pack containing sliding blocks designed for the Ultimaker S5, S7 and S8 professional 3D printers. Sliding blocks are the friction-fit precision components that guide printhead movement along the XY cross rods. Worn sliding blocks cause printhead play that manifests as dimensional inaccuracy, layer shifting or ghosting artifacts in prints. Replacing them with fresh OEM parts restores accurate XY motion and print quality.

The S5, S7 and S8 share the same sliding block specification, so this single pack covers all three models. This is the recommended service action for high-mileage S-series machines experiencing reduced print quality attributed to XY play. Sliding blocks should be inspected and replaced as part of regular preventive maintenance on production machines. Also available for UM2 (210000007271), S3 (210000007273) and UM3/2+C (210000007274).
