The shaft end processing section (effective thread length + approx. 10 mm) may experience reduced hardness due to the annealing effect of the processing.

If there are requirements for rust prevention, give priority to products with hard chrome plated surface treatment. Please click

Rust Prevention Methods

If used together with linear bearings, please select products with high-frequency quenching.

Product Features

Feature 1: Has high-precision dimensional tolerances and is widely used in various precision equipment.
Feature 2: Uses bearing steel (45 or GCr15) with excellent wear resistance and SUS440C or equivalent high-hardness corrosion-resistant steel, which are high-frequency quenched to enhance wear resistance while maintaining original toughness.
Feature 3: Various additional processing options are available to meet different usage environments.
Feature 4: Usually used in combination with linear bearing products, it provides excellent linear guidance. Compared to general shaft and bushing structures, even during high-speed reciprocating motion, there is minimal wear.
Feature 5: Optional hard chrome plating provides excellent rust resistance, and the coating hardness reaches HV750. It will not be easily worn when used with high-hardness workpieces.

Precautions

(2) Decreased hardness in the machined area
After quenching the base material, machining may cause some areas to lose hardness due to annealing:
- All external threads
-All steps
-Internal threads: When M ≥ D/2, double-hole internal thread type, hard chrome plated products made of SUS440C or equivalent high-hardness corrosion-resistant steel
-Additional processing for wrench slot (SC-WSC-SX)
-Additional processing for flat surface (FC-WFC)
-Additional processing for V-groove (VC-WVC)
-Except for full-length hardened type.

Only the shaded area of section D is hard chrome plated.

(3) Coating for Surface Treatment
After surface treatment of the base material, processing is performed. The following areas are not plated:
- Grooved section
-External thread section
-Internal thread section
-Wrench slot, V-groove, flat surface, cut surface
-The inside of the pipe-type guide shaft may rust if hard chrome plating is not applied.

Example of Use

Standard Linear Motion Mechanism	Functions of Standard Linear Motion Mechanisms (1) Using two guide shafts in parallel effectively prevents workpiece rotation (2) Improves the accuracy and load capacity of linear motion. (3) High-speed reciprocating motion can be achieved through the combination of guide shafts and linear bearings. (4) Lower running resistance, resulting in less wear on the corresponding workpiece.
