When using recirculating units, there is theoretically no limit to the stroke. The stroke is only limited by the length of the guideway.
Regarding the spacing K between recirculating units and the guideway spacing Q, the following ratios are recommended as guidance:
When using one recirculating unit per guideway:
Kt Q
≥ 1
When using multiple recirculating units per guideway:
K Q
≥ 1
| K | = Spacing between recirculating units (mm) |
| Kt | = Load-bearing length (mm) |
| Q | = Average guideway spacing (mm) |
