Custom Ball Screws by Drawing, Sample, or Application Requirement
Use custom service as an upgrade when standard parts, bars, or common models are not enough for installation. We quote by length, lead, nut type, accuracy grade, end machining, and packing requirement.
Sample replacement
Repair projects can start with old part photos, measured dimensions, nut form, and application conditions.
Repair and retrofitApplication selection
When drawings are incomplete, start with load, speed, stroke, mounting, accuracy, and quantity.

Specification details
Information usually needed before quotation.
Actual feasibility depends on diameter, length, accuracy grade, and end machining requirements. Send these details as clearly as possible.
| Item | Common buyer input | Why it matters |
|---|---|---|
| Diameter and lead | 1605, 1610, 2005, 2510, 3210 | Determines load, speed, and nut selection. |
| Total and thread length | Overall length and effective thread length | Affects stroke, support position, and packing risk. |
| Accuracy grade | Common starting points are C7 rolled or C5 ground | Balances price, positioning accuracy, and lead time. |
| Nut type | Single nut, double nut, flange form, preload requirement | Affects backlash, rigidity, mounting, and assembly size. |
| End machining | BK/BF, FK/FF, EK/EF, or custom drawing | Ensures the screw fits bearing supports and couplings. |
