    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. Please click Rust Prevention Methods
    If used together with linear bearings, please choose products with high-frequency quenching.

    Outer diameters 35, 40, and 50 are limited to E-PSFAA and E-PSFNA specifications only.
    For the N() dimension, only D tolerance g7 is available.
    The P dimension must satisfy M+3 ≤ P.
    When D-P ≤ 4 for the standard type, the chamfer C on the stepped section is less than 0.2.
    For the type with a step on one end and an internal thread on the other, the L dimension must satisfy N×3 ≤ L.
    When M×2.5 + 4 + N×2.5 + 4 ≥ (Y) for the standard type, the bottom of the threaded hole may penetrate through. When M×2 + N×2 ≥ (Y), the effective length of the larger diameter threaded hole takes priority. At this time, Y must satisfy Y ≥ M×2.5 + 4 + N or Y ≥ N×2.5 + 4 + M.
    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: Various additional processing options are available to meet different usage environments.
    Feature 4: Typically used in combination with linear bearing products, it provides excellent linear guidance. 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, offering 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 guide shafts with stepped ends and internal threads / stepped ends 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 double stepped internal thread type, double stepped 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.
