CONFIGURABLE LINEAR MOTION COMPONENT
Round-shaft systems are often a practical choice for moderate loads, easier alignment and replacement projects. The shaft support strategy matters: a long unsupported span behaves very differently from a continuously supported rail.
Selection data
| Guide architecture | Round shaft with linear bushing / pillow block |
|---|---|
| Shaft support | End-supported or continuously supported layout |
| Bearing style | Open, closed or adjustable architecture by application |
| Shaft diameter | Confirm from load, span and existing envelope |
| Shaft length | Project-specific |
| Mounting | Base, pillow-block or custom support arrangement |
Engineering note: Values shown as reference classes describe common market terminology, not a guaranteed stock list. Final dimensions, load ratings, accuracy/preload and interchangeability are confirmed against the application or drawing.
When this configuration fits
Choose round-shaft guidance when the mounting structure, tolerance strategy or replacement geometry favors a cylindrical shaft and bushing rather than a square profile rail.
What to send with your RFQ
Shaft diameter and length, open/closed bearing preference, support arrangement, moving load, span, speed, mounting photo and any current part number.
