What Are the Advantages of GUNRI Linear Shafts

Linear shafts are ideal for systems requiring accurate linear motion and smooth operation. Here’s why:

High surface hardness ensures wear resistance
Ground finish improves motion smoothness
Low friction coefficient with linear bearings
Corrosion-resistant coatings available (hard chrome, electroless nickel)
Compatible with CNC machines, 3D printers, robot arms, etc.

Types and Applications of Linear Shafts

We offer a wide variety of linear shafts to suit different use cases:

Type	Diameter Range	Length Range	Application
Hardened Linear Shafts	3–50mm	up to 1500mm	Automation, packaging, robotics
Chrome Plated Shaft Rods	6–50mm	20–1500mm	CNC guides, pick-and-place systems
Stainless Steel Linear Shafts	4–30mm	20–1200mm	Food-grade & medical machinery
Precision Hollow Shafts	8–30mm	100–1000mm	Weight-sensitive motion systems

Industries Served: Automotive assembly lines, textile machinery, semiconductor equipment, medical devices, and more.

How To Choose the Right Linear Shaft

Choosing the correct linear shaft depends on several factors:

Load Capacity – heavier loads require larger diameters and hardened materials
Motion Requirements – precision ground shafts for smooth, repeatable motion
Environment – select stainless steel for corrosive or clean-room conditions
Mounting Style – solid, hollow, support rail types
Shaft End Machining – threads, tapped holes, circlip grooves available

Surface Compatibility and Resistance of Linear Shafts

Our shafts undergo hard chrome plating, high-frequency induction hardening, or electroless nickel plating to meet your durability needs:

Hard Chrome Plating: 20–25μm layer, 900+ HV hardness
Induction Hardened Shaft: Surface HRC58–65, core toughness retained
Corrosion Resistance: 9Cr18 (SUS440C) for marine and chemical environments
Compatible with linear bushings, LM guides, and slide bearings

Difference Between Linear Shaft and Rotary Shaft

Feature	Linear Shaft	Rotary Shaft
Motion Type	Linear (reciprocating)	Rotational
Tolerance	IT6–IT7 (high precision)	IT7–IT9
Surface Treatment	Chrome-plated or nitrided	Often raw or coated
Application	Linear guides, automation	Motors, spindles

While rotary shafts rotate within bearings, linear shafts are designed for smooth axial movement, often with ball bushings or sleeve bearings.

FAQ

Q1: What’s the difference between a hardened shaft and a chrome plated shaft?
A: Hardened shafts have high surface strength through heat treatment, while chrome plated shafts add corrosion resistance and reduce friction. Most of our shafts are both hardened and plated.

Q2: Can I get a custom linear shaft with end machining?
A: Yes. We provide OEM linear shafts with custom end machining, including tapped holes, circlip grooves, flat milling, and threading.

Q3: What tolerances do your shafts support?
A: Standard tolerance is g6/h6, but we can offer h7, h8 or customized based on application. For precision linear shafting, straightness can be < 0.02mm per 300mm.

Q4: What is the maximum length you can manufacture?
A: For most shaft types, we support up to 1500mm in a single piece. For longer shafts, we can offer coupling solutions.

Q5: What is the MOQ for linear shafts?
A: We support low MOQ orders, even as low as 5 pieces for stock models. For special customization, MOQ may vary.

Q6: Do your shafts fit standard linear bearings?
A: Yes. Our shafts are compatible with LM and LME series bearings (e.g. LM10UU, LMK12UU), and precision linear motion systems.

Q7: What materials are available?
A: GCr15 (SUJ2), 9Cr18 (SUS440C), S45C. Stainless types are best for corrosion resistance; carbon steel types are ideal for high-load and cost-sensitive projects.

Q8: Can you ship internationally?
A: Absolutely. We ship to Europe, the US, Southeast Asia, and the Middle East. Support includes DDP, DAP, EXW, and FOB terms.
