The machined part at the shaft end (effective thread length + approx. 10 mm) may have reduced hardness due to the annealing effect of machining.
If rust prevention is required, please give priority to products with hard chrome plating Surface Treatment. For rust prevention methods, please click Rust Prevention Methods
If used together with linear bearings, please select products with high-frequency quenching.

Product Features
Feature 1: Offers high-precision dimensional tolerances and is widely used in various precision equipment.
Feature 2: Uses bearing steel with excellent wear resistance (45 or GCr15) and SUS440C or equivalent high-hardness, corrosion-resistant steel, which undergo high-frequency quenching to enhance wear resistance while maintaining original toughness.
Feature 3: A variety of additional processing options are available to meet different usage environments.
Feature 4: Typically used in combination with linear bearing products, it offers excellent linear guiding performance. Compared to standard shaft and bushing structures, even during high-speed reciprocating motion, there is minimal wear.
Feature 5: Hard chrome plating is available as a Surface Treatment, providing excellent rust resistance. The coating hardness reaches HV750, so it will not be easily worn even when used with high-hardness workpieces.
Precautions
MISUMI high-precision straight guide shaft with stepped internal thread on one end — Selection catalog(2) Reduced hardness in machined areas
 After quenching the base material, machining may cause reduced hardness due to annealing in the following areas:
- All external threads
- All steps
- Internal threads: When M ≥ D/2, double-hole internal threads, and hard chrome plated products made of SUS440C or other high-hardness corrosion-resistant steels
- Additional machining of wrench slots (SC-WSC-SX)
- Additional machining of flat surfaces (FC-WFC)
- Additional machining of V-grooves (VC-WVC)
- Except for fully hardened types.
Only the shaded area in section D is hard chrome plated.
Guide shaft with stepped internal thread on one end bushing, MISUMI quality, Japanese imported stainless steel material		(3) Plating after Surface Treatment
 After Surface Treatment of the base material, machining is performed, and the following areas are not plated:
- Groove areas
 -External thread sections
 -Internal thread sections
 -Wrench slots, V-grooves, flat surfaces, and cut surfaces
 -The inside of pipe-type guide shafts is not hard chrome plated and may rust.
Example of Use
Standard Linear Motion MechanismFunctions of the Standard Linear Motion Mechanism
(1) Using two guide shafts in parallel effectively prevents the workpiece from rotating.
(2) Improves the accuracy of linear motion and load-bearing capacity.
(3) High-speed reciprocating motion can be achieved through the combination of guide shafts and linear bearings.
(4) Low running resistance, resulting in less wear on the corresponding workpiece.
