How to Identify DLY Ball Screw Specifications

DLY ball screw model codes include information such as nut type, thread direction, shaft diameter, lead, ball circulation structure, flange type, production process, accuracy grade, shaft length and preload or clearance requirement. Understanding these codes helps buyers confirm the correct ball screw before quotation, production and installation.

DLY ball screw model number identification guide

What This Code Helps Buyers Confirm

A complete ball screw code can help confirm the main product structure before quotation. If your current model code is incomplete, DLY can also check the specification according to your drawing, sample photo or basic dimensions.

Nut Type / Direction / Shaft Diameter / Lead / Circuits / Accuracy Grade / Overall Length / Preload / Clearance
No. Code Item Meaning Explanation for Buyers
1 Nut Type Codes SFS, DFS, SFI, DFT, SFT, SFV, DFV, SFE, SFK, SBH, SCI
S: Single nut
D: Double nut
F: With flange
C: Without flange
U: DIN nut
T: T type nut
I: I type nut
V: V type nut
E: E type nut
K: K type nut
The nut type affects installation structure, flange shape, mounting space, rigidity and replacement compatibility. Buyers should confirm the nut code before ordering or replacing an existing ball screw.
2 Direction of Helix R: Right
L: Left
R means right-hand thread and L means left-hand thread. Right-hand ball screws are more common, while left-hand ball screws should be clearly marked when required.
3 Shaft Diameter Shaft dia. (mm) Shaft diameter is shown in millimeters. It affects load capacity, rigidity, installation size and matching support units.
4 Lead Lead (mm) Lead means the linear travel distance of the nut when the screw rotates one revolution. It affects speed, torque and positioning performance.
5 Number of Turns / Circuits / Rows No. of Turn / Circuits of Turn × Row This code shows the ball circulation structure inside the nut. It is related to load capacity, nut length, rigidity and service performance.
6 Flange Type N: Not cutting
S: Single cutting
D(U): Double cutting
Flange type should match the machine mounting direction, installation space and nut fixing method.
7 Production Code G(P): Grinding
F(T): Rolled
Grinding is usually used for higher precision requirements. Rolled ball screws are suitable for general automation, regular models and batch purchasing.
8 Accuracy Grade Code C0, C1, C2, C3, C5, C7, C10 The accuracy grade should be selected according to positioning accuracy, repeatability requirement, machine type and budget.
9 Overall Length of Shaft Overall length of shaft (mm) Overall shaft length should be confirmed together with effective stroke, end machining length and support unit distance.
10 Axial Clearance and Preload Code P0, P1, P2, P3, P4 This code is related to axial clearance and preload. Buyers should confirm it according to backlash control, rigidity, running smoothness and application requirements.

How to Choose the Right Ball Screw

Choosing a suitable ball screw is not only about selecting a diameter or comparing price. For CNC machines, automation equipment, linear modules, woodworking machinery and industrial motion systems, buyers usually need to confirm the screw diameter, lead, total length, nut type, accuracy grade, end machining, load, speed and installation space.

If you are replacing an existing ball screw, the model number, sample photo or drawing is very helpful. If you are designing a new machine, DLY can help check the basic selection details according to your application and motion requirements.

1. Confirm the Screw Diameter

The screw diameter affects load capacity, rigidity, installation size and matching support units. Common ball screw diameters include 12 mm, 16 mm, 20 mm, 25 mm, 32 mm, 40 mm and larger sizes.

2. Select the Proper Lead

Lead means the linear travel distance when the screw rotates one revolution. A smaller lead is often used for better control, while a larger lead is suitable for higher speed movement.

3. Check the Total Length

Total length should be confirmed together with effective stroke, end machining length and installation distance. For customized ball screws, a drawing is recommended before production.

4. Choose the Nut Type

Nut type should match the installation space, flange direction, load requirement and machine structure. Common options include single nut, double nut, flanged nut and compact nut structures.

5. Select the Accuracy Grade

C5, C7 and C10 ball screws can be selected according to positioning accuracy, repeatability, machine type and budget. Ground ball screws are used for higher precision requirements, while rolled ball screws are suitable for many general automation applications.

6. Confirm End Machining

End machining should match the support unit, bearing seat, coupling, motor connection and installation drawing. DLY can support cutting, thread processing, keyway, bearing seat and other end machining requirements.

7. Consider Load and Speed

Load, speed and working direction affect ball screw selection. Vertical installation, heavy load, high speed or long stroke applications may require more careful confirmation.

8. Match Related Components

Ball screws are often used with support units, couplings, nut seats, linear guideways and motors. Matching related components correctly helps reduce installation problems.

Ball Screw Use and Maintenance Notes

Ball screws are precision transmission components. Correct handling, lubrication, dust protection and installation alignment can help reduce abnormal wear, noise and early failure.

The following notes are a short maintenance guide for buyers, machine builders and equipment users. For detailed installation, lubrication interval and troubleshooting instructions, DLY can provide further technical communication according to the machine condition.

Cautions about use of ball screw and nut assembly

Cautions About Use

Avoid hitting the screw thread, ball track or nut body with hard tools. Do not remove the nut from the screw without a suitable transfer sleeve, otherwise the steel balls may fall out and damage the assembly.

L

Lubrication

Adequate lubrication is necessary during ball screw operation. Insufficient lubrication may increase friction, wear, heat and service-life risk.

Lubricating oil or grease should be selected according to speed, load, working environment and maintenance plan. The lubrication condition should be checked regularly during equipment use.

Ball screw dust proof and prevention structure

Dust Proof and Prevention

Chips, dust, water or cutting oil may increase friction and cause ball screw damage. When foreign matter may enter the screw area, a bellows, telescopic cover or suitable protection structure is recommended.

Ball screw offset load warning for installation alignment

Offset Load

Offset load or poor installation alignment may affect running smoothness, noise and service life. Before operation, check whether the screw, nut, support unit and guide system are properly aligned.

Quick Maintenance Reminder

During regular maintenance, check lubrication condition, contamination, abnormal noise, rough running feel and protection cover condition. Replenish or replace lubricant according to the machine working condition, speed, load and operating environment.

Check lubricant condition
Keep chips and dust away
Avoid nut disassembly without a sleeve
Check alignment before running
