The hardness of shaft end machined part (effective thread length + approx. 10mm) may be reduced due to the annealing effect of machining.
If there are requirements for rust prevention, please give priority to the hard-chrome plated products. Click Rust Prevention Method
For combination with linear bushing, please select high-frequency quenched products.

P dimension requires M+3≤P.
When D-P≤4 for the standard type, chamfer C on the step part is 0.2 or less.
L dimension for One End Stepped One End Tapped requires N×3≤L.
When M×2.5＋4＋N×2.5＋4≥(Y) for the standard type, tap pilot holes may go through. When M×2＋N×2≥(Y), priority is given to the effective length of threaded holes with larger diameters. In such case, Y requires Y≥M×2.5＋4＋N or Y≥N×2.5＋4＋M.
Alterations
MISUMI Linear Guide Shafts One End Stepped Both Ends Tapped/One End Tapped All Models Machining
Product Features
Feature 1: Extensively applied in various precision equipment thanks to high precision dimensional tolerance.
Feature 2: Bearing steel (S45C or GCr15) with excellent wear resistance and SUS440C or equivalent high hardness corrosion resistant steel are used for high frequency quenching, maintaining the original toughness while enhancing abrasion resistance.
Feature 3: A variety of alterations are available to accommodate different environments.
Feature 4: Usually combined with linear bushing products, achieving excellent linear guiding functionality, and less abrasion even if subject to high-speed reciprocal motion, as compared with general shaft and bushing structure.
Feature 5: The surface treatment of hard-chrome plating is available, achieving excellent anti-rust performance and HV750 plating hardness, as well as less abrasion when used in combination with high-hardness workpieces.
Precautions
MISUMI High Precision Guide Shafts Both Ends Stepped and Tapped Both Ends Stepped Selection Catalog②Reduced hardness of machined parts
 Machining is performed after quenching of base metal. The parts that may be reduced in hardness due to annealing are:
 -All threaded
 -All stepped
 -Tapped: when M≥D/2, tapped double-hole type, hard chrome plated products made of SUS440C or equivalent high hardness corrosion resistant steel
 -Adds wrench flats (SC-WSC-SX)
 -Adds screw flats (FC-WFC)
 -Adds V-grooves (VC-WVC)
 -Except for full length hardened type.
Only the shaded portion of D part is hard chrome plated.
Guide Shafts Both Ends Stepped and Tapped Both Ends Stepped Bushing MISUMI Quality Stainless Steel Material Imported from Japan		③Plating of surface treatment
 Machining is performed after surface treatment of base metal. No electroplating treatment is applied to the following parts:
 -Groove part
 -Threaded part
 -Tapped part
 -Wrench slot, V-groove, plane, cut section
 -The inside of the tube-type guide shaft may rust without hard chrome plating.
Example of Use
Standard Linear Motion MechanismFunctions of standard linear motion mechanism
①Side-by-side use of two guide shafts effectively prevents workpiece rotation
②Improved accuracy of linear motion and load capacity.
③The combination of guide shaft and linear bushing enables high-speed reciprocal motion.
④Low operational resistance, reducing the loss of workpiece.
