Pulley Pack, Ultimaker S Series

Pulley Pack, Ultimaker S Series

This Pulley Pack contains all pulleys and spacers required for the proper operation of the gantry system on Ultimaker S Series printers. It includes two motor pulleys (ID 5 mm, OD 15.5 mm), seven regular pulleys (ID 8 mm, OD 15.5 mm), one gear ratio pulley (ID 8 mm, OD 24 mm), and one double pulley (ID 8 mm, OD 15.5 / 24 mm). The included plastic spacers (3x 3 mm, 3x 8 mm, 1x 12 mm, and 1x 25 mm) facilitate installation and perfect alignment of the pulleys on the gantry.

Each pulley is designed to provide smooth movement and reliable transmission between motors and axes, minimizing wear and preserving print accuracy. The pack is compatible with S3, S5, S6, S7, and S8 models.

Usage Tips

• Check pulley alignment before tightening to ensure uniform gantry movement.
• Apply a light suitable lubricant on the axes to reduce friction and extend pulley lifespan.
• Replace all pulleys and spacers simultaneously if signs of wear are detected to maintain print precision.
• Regularly clean the gantry system to prevent dust or residue buildup that could affect smooth operation.

Integrating this Pulley Pack into your Ultimaker S Series ensures optimal X and Y axis performance, improved print consistency, and increased printer longevity.
