Product Description

 

Linear shaft is chrome plated and induction hardened, precision ground, and polished to the tolerances required by the demanding linear motion industry.It is suitable for use with linear support blocks and closed type slide units in linear motion applications. The high-carbon steel shaft is chrome plated for corrosion resistance, case hardened for wear resistance, and precision ground for consistent ball bushing radial clearance. The shaft diameter and length are specified for accurate fit and this shaft is suitable for use in applications, such as measuring systems, printing equipment, and computer numerical control (CNC) tools.

1.Linear shaft features

Straightness	Max5.0µm	Max5.0µm	Max5.0µm
Chrome thickness	20-30µm	30µm	30µm
Roughness	Max1.5µm	Max1.5µm	Max1.5µm
Process machinized	Threading, reduced shaft dia,coaxial holes drilled and tapped, flats-single or multiple, key way, snap ring grooves, radial holes drilled and tapped, chamfering

1.Good finish and straightness: The surface is treated by sp
ecial grinded, and then mirror polished. The surface is smooth, without cracks.
2.Corrosion resistance: Surface chrome plated(10um-20um)
3. Durable resistance: Adapting C45 high quality steel, high frequency hardness degree HRC60 ~ 64
4.High Accuracy : G6;Diameter tolerance:-0.005mm-.0.27mm; Length tolerance:+/-0.5mm(1M-3M);+/-1mm(3M-6M)
5. High Fitness: Chamfer on both ends, easier to install linear bearings and won't hurt fingers when installing it.

2.Three types of the linear shaft

 

Chorme Plated Shaft

Hollow Shaft

Shaft With Process

3.There are many different kinds of machinning process we can do

 

Processing machinized Radial holes drilled and tapped

 

Processing machinized Coaxial holes drilled and tapped

 

 

 

Processing machinized Flats---Single or Multiple

 

Processing machinized Snap ring grooves

Processing machinized Reduced shaft dia and threading

 

 

4.Test the quality according to cusdifferent requirements

 

Straight the linear shaft straightness:

We control the traighness 0.05mm of linear shaft 300mm

 

Test hardness:

S45C materail induction linear shaft, the hardness is HRC55-58

GCr15 (SUJ2) materail induction linear shaft, the hardness is HRC58-63

If flexible shaft, the hardness is based on the shaft material itself

Test linear shaft surface roughness

the max roughness is Ra0.4um

Test the linear shaft dia precision, as usually, h7 is the normal tolerance in our stock, But we can offer g6, h6 precision too. if any special tolerance, we are able to customize them for you.
