Mini Ball Screw for Micro Feed and Fine Positioning Modules
DLY mini ball screw is made for small precision mechanisms that need short travel, fine feed movement and smooth linear response in a very limited space. It is mainly used in optical focusing units, laboratory sample stages, sensor alignment structures, measuring instruments and micro adjustment modules.
For this type of product, the important point is not only the screw model. Buyers need to confirm shaft diameter, fine lead, nut envelope, usable stroke and shaft end connection. DLY helps check these details before quotation so the mini ball screw can fit the real module design.
Mini Ball Screw: What Buyers Should Confirm First
Mini ball screw orders are sensitive to size. A small difference in nut diameter, shaft end length or usable stroke may affect final assembly. Before quoting, DLY recommends confirming the real installation space instead of choosing only by model name.
Nut Envelope
Confirm nut outer diameter, flange space and mounting position before ordering.
Usable Stroke
Check the real travel after nut length and shaft end machining are deducted.
End Connection
Bearing seat, thread, flat position or coupling end should match the module design.
Where Mini Ball Screws Are More Suitable
Optical Focusing
Used for lens, sensor or small platform adjustment where movement should be fine and stable.
Sample Positioning
Suitable for short-distance sample movement in laboratory or measuring structures.
Sensor Alignment
Used when a small sensor, probe or measuring head needs controlled mechanical adjustment.
Micro Dosing
Can be used in light-load feeding or adjusting structures that require repeatable small movement.
Mini Ball Screw Quotation Checklist
Send the following details to DLY for faster model confirmation and quotation.
| Information | What to Provide | Purpose |
|---|---|---|
| Screw Size | Diameter, lead and total length if known. | Confirm the basic mini ball screw direction. |
| Available Space | Nut space, bearing space and housing size. | Check whether the screw nut can fit the structure. |
| Required Stroke | Actual movement distance needed. | Avoid insufficient usable travel after assembly. |
| End Machining | Bearing seat, thread, flat, coupling end or drawing. | Ensure the screw can connect with the module correctly. |
| Quantity | Sample, trial order or batch order. | Confirm price, production and delivery plan. |
