Straightness is one of the most important quality characteristics for precision guide shafts, but it's often overlooked. Why does it matter so much?

- Increased friction and wear: A bent shaft causes binding and increases wear on both the shaft and the linear bearings

- Poor motion quality: The movement becomes jerky instead of smooth

- Increased stress: Bending stresses reduce service life

- Accuracy loss: Positioning accuracy suffers, which is critical for automation and machining applications

 

- Proper material selection with good inherent straightness

- Stress relieving after rough machining

- Precision grinding processes that maintain and improve straightness

- Final inspection to ensure straightness meets tolerance requirements

 

At Xinluo Hydraulic, we maintain strict straightness tolerances throughout the manufacturing process and inspect every guide shaft before shipment. Your linear motion system depends on straight guide shafts for smooth, accurate operation — and we deliver that precision.
