ASM SIPLACE 03020301 is a Bosch Rexroth Size 15 linear guide carriage used in the machine axis / gantry motion system. It provides the mechanical sliding interface between the moving assembly and the guide rail, so it should be treated as a carriage-level maintenance part rather than a motor, encoder or servo component.
This part is worth checking when axis movement becomes rough, develops abnormal mechanical noise, shows noticeable play at the carriage and rail interface, or feels uneven at particular travel positions. These observations point to the mechanical guide system for inspection, while motor, drive and position-feedback faults should remain separate diagnostic paths.
03020301 Guide Carriage Specifications
| Part Number | 03020301; documented version includes 03020301-01 |
|---|---|
| Part Type | Linear Guide Carriage / X-Axis Slider |
| Manufacturer Reference | Bosch Rexroth |
| Guide Size | Size 15 / Gr.15 |
| System Area | Axis / gantry mechanical motion system |
| Common Selection Risk | Confusion with other SIPLACE guide carriages that use a different rail size or carriage family |
| Related Guide Trolley | 00345186 – KWVE 25 H guide trolley; different guide-system family and not a direct substitute |
| Core Matching Point | Complete P/N, carriage size, installed rail system, machine position and original slider dimensions |
03020301 and 00345186 are both SIPLACE linear-guide components, but they should not be grouped as interchangeable “sliders.” 03020301 is documented as a Bosch Rexroth Size 15 carriage, while 00345186 is a KWVE 25 H guide trolley. Selecting the wrong carriage leaves the mechanical repair unresolved and can delay machine restart while the correct guide component is sourced.
If 03020301 has already been identified as the worn carriage, send the existing P/N, machine model, installation position and required quantity for availability checking. Photos of the removed slider and guide rail are useful when the original label is difficult to read.
