1.Depth of Effective Hardened Layer for Quenched Guide Axis
2.Heat Treatment and Surface Treatment of Guide Axis。
Unless specifically required for full-length heat treatment or surface treatment, the heat treatment hardness or surface treatment of conventional guide axes only refer to the outer circular part marked with 180 in the figure below. Other parts (such as stepped parts, internal threads, external threads, wrench slots, internal holes, optional processing areas, etc.) have no quenched layer or hard chromium layer.
3.Rust Prevention and Installation of Guide Axis
Guide axis products are coated with anti-rust oil before leaving the factory;
When installing the guide axis, please wear gloves to avoid contact with sweat or water stains. After installation, anti-rust oil should be applied, and rust prevention maintenance should be performed frequently during use;
When storing and installing non-hard chromium plated models made of SUJ2 or S45C materials, special attention should be paid to rust prevention, as they are prone to rusting.

Cancel snap ring groove on one end Move the L dimension position to the outside of the snap ring groove
2.Keyed Type Internal Thread on One End
Precision Grade Ordinary Grade Precision Grade
Please note that the hardness of the shaft end processing part (effective thread length + approximately 10mm) may decrease due to the annealing effect of processing. For more details, please refer to the overview of the guide shaft.
Selection: Precision Grade is not applicable for L>300
Change internal thread to fine thread Pitch Fine Thread
When selecting, please change M to MC
M and MC must be of the same size
Applicable to Ordinary Grade only
3.Type with Wrench Slot
Deformation near the through hole may occur due to the annealing effect of processing, causing the outer diameter tolerance to exceed the specified value.
Specify the S dimension according to the usage requirements
Refer to the guide shaft product brochure for the wrench slot size
4.Internal Thread on Both Ends
The two wrench slots are not located on the same plane.
