When a small depression appears in a linear bearing, it may be a major problem

‍

The linear optical axis has the guiding effect of sliding bearings, which can enable products to implement linear motion. Generally, it has the advantages of low friction coefficient, high accuracy, and high transmission efficiency, so it is used in products with precision slender shafts as components such as oil cylinders, cylinders, engineering machinery, packaging machinery, etc.

The straight optical axis can be divided into hard axis, soft axis, and quenched and tempered axis. Different requirements require different optical axes. When improving wear resistance, a high hardness optical axis is needed. The harder the metal material, the more wear-resistant it is. Generally, hard shafts can be used in conjunction with linear bearings.

So, what are the differences in craftsmanship between hard and soft axes in the optical axis?

Hard shaft refers to a linear optical shaft with a surface high-frequency quenching and a hardness generally reaching around HRC60, which can be used in conjunction with linear bearings

A soft shaft is a linear optical shaft without surface hardening treatment, generally used for rotating devices. The soft shaft has not undergone high-frequency quenching, and its hardness is generally HB200-300, equivalent to around HRC25.

Quenching and tempering shaft: It is a dual heat treatment of quenching and high-temperature tempering. The answer is to make the workpiece have good comprehensive mechanical properties, and the hardness is generally around HRC28-32 degrees.

The optical axis of Hengli Auto Parts can be used as a soft axis or as an unplated axis.
