Product Description

Product Description

Ground and Rolled Ball Screw

We have 12mm(SFU1204),16mm(SFU1605,SFU1610,SFU1616),20mm(SFU2005,SFU2010,SFU2020),25mm,32mm,40mm,50mm,60mm,80mm ball screw
 
The major differences between a rolled and ground ball screw are the manufacturing process, the lead error definition and
geometrical tolerances. Rolled ball screws are made through a rolling process of the screw spindle instead of a grinding process. Rolled ball screws provide smooth movement and low friction which can be supplied quickly from stock, at a lower production cost.

Reasons for Choosing Us

Our high-quality ground and rolled ball screws deliver exceptional motion control for industrial applications, ensuring:

1.Ultra-Smooth Movement

Low friction design provides buttery-smooth linear motion, eliminating stick-slip effect for higher machine accuracy.

2.High-Speed Operation

Optimized ball recirculation enables fast, stable movement (up to 3m/s), perfect for CNC machines and automation systems.

3.Superior Positioning Precision

Ground screws (C0-C3 grade) achieve micron-level repeatability (±0.005mm), while rolled screws (C5-C10) maintain excellent cost-performance balance.

4.Minimal Backlash & Noise

Precision preload adjustment ensures near-zero backlash, while hardened steel construction reduces vibration and noise (≤55dB).

5.Long Service Life

Advanced heat treatment and wear-resistant alloy balls extend lifespan even under heavy loads (up to 50kN dynamic load capacity).

6.Energy Efficient

90%+ mechanical efficiency reduces motor power consumption compared to trapezoidal screws.

Packing & Delivery

1.Sample order be packed by paper carton for saving freight charge

2.Bulk order delivered by sea will be packed by film and wooden carton

3.According to the customer's requirements
