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.

Product Features

Feature 1: Offers high-precision dimensional tolerances and is widely used in various precision equipment.
Feature 2: Uses bearing steel (45 or GCr15) with excellent wear resistance, as well as SUS440C or 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

(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 high-hardness corrosion-resistant steel
- 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

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 Mechanism	Functions 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.
