Sliding Guides Pt 3: Components & Materials

Since there are a variety of environments and application requirements, linear bushings and shafts must accommodate for such needs.  In this post, we will display the different material types and application specifications they can be applied to.

Sliding guide components such as linear bushings and shafts are used quite frequently in an application similar to the below photo and figure. See Photo 1 and Figure 1.

In these sliding guide designs, the shafts are supported on both ends with the load traveling on the plate via the linear bushings.  The load is transferred to each of the guide shafts.  Linear bearings or linear bushings can be used in this design depending on the desired outcome.

Shafts and bushings each require some fabrication for installation, but the costs could be reduced by adopting the mounting designs for standardized products.

Below is a chart illustrating standard linear sliding guide components, the material, and application characteristics.

Component Material Mounting Styles Application Characteristics
Shafts SUJ2 High Frequency Induction Hardening (See Note 1 & 2)

SUJ2 High Frequency Induction Hardening:58HRC+hard chrome plating: 800HV
(See Note 3)

Note 1) About SUJ material
Bearing Steel. S for Steel, U for Used, and J for Journal. Journal is a rotating contact section of a bearing arrangement.
Note 2) About High Frequency Induction Hardening
A hardening method where only the surface of steel is hardened by efficiently induced electrical current by a high frequency oscillator.
Note 3) About Hardness
There is no theoretical definition for Hardness, and is expressed using comparative values obtained by pressing hard balls or diamond indenters on test specimen. HRC (Rockwell hardness: Hard-ball Method) is used for SUJ and SUS hardness measurements and Hv (Vickers Hardness: Vickers Pyramid Indentation Method) for hardness of minute section of hard chrome plating is generally used.

Sliding guide components can be combined to achieve application requirements.  The availability of different materials and surface treatments make this possible.  As you can see, each component has a variety application characteristic capability.

This concludes the sliding guide series.  Up next we will dive into CAD a series including topics such as PDM, CAD history, and future.

  • We absolutely love this #application of Aluminum Extrusion from @silver_sequoia ! Like true #engineers mocking up a CAD model, assembly, and finished product they showed anything is possible with this versatile product. We think all airstream trailers should include AEX. 😉what do you think? Thank you Shane and Cynthia! 👍🏼
