SFU4010 6.35mm Grinding Self-lubricating Heavy Duty Ball Screw
ZLV is proud to introduce the SFU4010 6.35mm Grinding Self-lubricating Heavy Duty Ball Screw. This innovative product, custom-built and tailored to perfection, is the embodiment of precision engineering, high load-bearing capabilities, efficient energy consumption, and advanced self-lubricating technology.
Features and Characteristics
Our SFU4010 ball screw offers numerous features and advantages:
- Low Frictional Loss and High Transmission Efficiency: The ball screw employs a large number of rolling balls for its operation, resulting in high motion efficiency. Compared to traditional sliding screws, its drive torque is less than 1/3, ensuring less power is needed for the same movement results.
- High Precision: Our ball screws are produced by world-class mechanical equipment, guaranteeing top-tier precision. With stringent control over factory environment conditions such as temperature and humidity, the high precision of these ball screws is ensured under a robust quality management system.
- High-speed Feed and Micro-feed: Due to its rolling motion, our ball screw requires minimal start-up torque, eliminating the creeping phenomenon observed in sliding movements. This results in highly precise micro-feed capabilities.
- High Axial Rigidity: The ball screw can apply preload, achieving high rigidity by making the axial clearance negative. This enhances stiffness and performance, especially when dealing with high load or high-speed operations.
- Non-self-locking with Reversible Transmission: The ball screw is non-self-locking, which facilitates smoother movement and reversible transmission.
Structure and Classification
The ball screw comprises the screw, nut, steel ball, preload piece, reverser, and dust-proof device. It can be classified into:
- Self-lubricating Ball Screw: This type comes with a removable oil device, eliminating the need for a lubrication system, thus reducing oil change and waste oil treatment costs.
- Silent Ball Screw: This variant includes a special groove ball spacer to mitigate the noise produced from ball-to-ball collisions, ensuring smooth, quiet operation.
- High-speed Ball Screw: Suitable for high acceleration, high rigidity, high-speed feed, low vibration, and low noise applications, such as in high-speed cutting centers.
- Heavy-duty Ball Screw: Designed to withstand significant axial loads, this type is applicable for electric design machines, air compressors, semiconductor manufacturing devices, and forging manufacturing devices.
Specification
Let’s look at the detailed specifications of the SFU4010 model:
| Parameters | SFU4010 Model |
|---|---|
| Shaft Diameter (d/mm) | 40 |
| Lead (I/mm) | 10 |
| Steel Ball Diameter (mm) | 6.35 |
| Nut Size (D, A, B, L, W, H, X,Q,n) | 63, 93, 14, 93, 78, 70, 9,M8,1*4 |
| Load(Ca) | 5399 |
| Weight (Screw Rod/M, Nut/pcs) | Screw rod: 10, Nut: 0.6 |

The parameters like nominal diameter, lead, length, nut form, and precision all play a significant role in the functioning of the SFU4010 model.
Detailed Analysis
Lead and its Impact on Screw Thrust:The lead of the ball screw indicates the distance the nut moves linearly when the screw rotates once. In this case, the lead is 10mm. The larger the lead, the higher the linear speed at the same rotation speed. It is calculated as follows:
v = r * i
- v: Nut’s moving speed (mm/s)
- r: Screw’s rotation speed (r/s)
- i: Lead (mm)
The relationship between lead and screw thrust is as follows:
F = (2πT*n) / i
- F: Screw thrust (N)
- T: Torque provided by the motor (N·m)
- n: Transmission efficiency (85%-95% for ball screws)
- i: Lead (m)
Length:Two aspects of length are crucial for our ball screw: overall length and thread length. Some manufacturers consider only the total length, while others require the thread length. Thread length comprises the thread’s total length and the effective stroke, which is the theoretical maximum length of the nut’s linear movement.
Nut Form:There are numerous forms of nuts listed in product samples from various manufacturers. We offer nuts in different flange styles, including round flange, single-cut flange, double-cut flange, and non-flange. There are also single nuts and double nuts, with the latter capable of adjusting preload.
Precision:The SFU4010 ball screw conforms to domestic precision levels P1, P2, P3, P4, P5, P7, and P10, adhering to the JIS standards of C0, C1, C2, C3, C5, C7, and C10 from Japan, Korea, and Taiwan Province of China, and also European standards IT0, IT1, IT2, IT3, IT4, IT5, IT7, and IT10.
The ZLV SFU4010 6.35mm Grinding Self-lubricating Heavy Duty Ball Screw represents the pinnacle of precision engineering and modern design, catering to a broad range of industrial applications and requirements. We hope this comprehensive product guide assists you in making an informed decision.
