·The hardness of the processed part is reduced after the base metal is annealed.
In the following examples (processed part and its front and rear positions), the hardness may decrease due to the annealing effect of processing.

The parts that may be reduced in hardness due to annealing are:
·Female thread: when M≥D/2
·Wrench slot alteration (SC·WSC·SX)
·Plane alteration (FC·WFC)

Frequently asked question (FAQ)

Question: Why are stainless steel guide shafts rusting?
Answer: Guide shafts are made of SUS440C, which are quenched for better abrasion resistance, but the material itself is weak to corrosion. Therefore, please select hard chrome plated products for applications with higher anti-rust requirements.
Question: Why is the hardness measured on the end face center is rather low in contrast with high hardness indicated for guide shaft products in the catalog?
Answer: As the guide shaft is high-frequency quenched, a hardening layer of certain depth will form on the outer circle of the guide shaft. To ensure toughness, the material will retain original hardness at the center of the guide shaft.
Question: What are the advantages of combining guide shaft with linear bushing?
Answer: Due to rolling friction fit with the linear bushing, the guide shaft can achieve high-accuracy linear motion, causing less friction resistance to the workpiece, thus suitable for extended continuous operation.
Question: How to select models of shaft products requiring a length of 100.5mm?
Answer: The total length can be customized in 0.1mm increments with LKC alteration.
Question: Why is the end face of hard chrome plated guide shaft rusting?
Answer: The guide shaft is cut after surface treatment during material preparation. Thereafter, no surface treatment will be performed, so the cut surface is not hard-chrome plated, thus causing the end face to rust.
Question: When combined with linear bushing, some guide shafts fit closely, while others fit with clearance. Does it affect usage?
Answer: The guide shaft and linear bushing fit with each other by point-contact rolling through the steel ball circulating structure. Due to the point-contact and non-interference fit, some clearance between the shaft and the bushing is normal, which will not affect usage. The use of this structure greatly reduces frictional resistance and improves service life of the workpiece.
Question: Is the stainless steel material of MISUMI guide shafts imported?
Answer: Both the bearing steel (SUJ2) and stainless steel (SUS440C) of MISUMI guide shafts are materials imported from Japan.
Question: I hope to know about the detection method and specification accuracy of the straightness of guide shafts.
Answer: Support both ends of the guide shaft with V-shaped blocks, rotate the shaft for 1 turn at any point, and measure the amplitude of the dial meter. 1/2 of the amplitude measurement value is the straightness. Straightness varies with outer diameter and length.
Question: How much is the perpendicularity accuracy of guide shaft?
Answer: The perpendicularity of guide shaft is 0.2 for standard type and 0.03 for precision type.
