Product Description

SFS4010-628-763-C7--40mm Diameter Rolled Ball Screw

How to Select Ball Screws

1. Number of Ball Circuits

This parameter is generally marked after the lead in the model, such as 4010-4, where the "-4" indicates the number of ball circuits.

2. Preload

Also known as pre-tensioning. For preload, a higher grade means a tighter fit between the nut and the screw, while a lower grade means a looser fit. The principle to follow is: select a higher preload grade for large diameters, double nuts, high precision, and larger driving torques; otherwise, select a lower grade.

3. Lead

Also known as pitch, which is the linear movement distance of the nut when the screw rotates one full turn. The lead is related to the linear speed: when the input rotation speed is constant, a larger lead results in a faster speed.

4. Ball Diameter

This parameter refers to the diameter of the rolling elements. It is not reflected in the model but is marked in the technical parameter tables of each manufacturer. It is generally related to the nominal diameter and lead.

5. Accuracy

Generally:

Select C7 (positioning error within ±0.05 for any 300 mm stroke) or lower for general machinery or ordinary CNC machinery.

Select above C5 (±0.018) and below C3 (±0.008) for high-precision CNC machinery.

Select above C3 for optical or inspection machinery.

6. Nominal Diameter

That is, the outer diameter of the screw. The nominal diameter is proportional to the load: the larger the diameter, the greater the load capacity.

7. Nut Type

Classified by flange type: approximately round flange, single-cut flange, double-cut flange, and non-flange types.

Classified by nut length: single nut and double nut.

8. Manufacturing Method Code

There are mainly two manufacturing methods for ball screws:
