Linear Shaft Rod

Linear Shaft Rod is case hardened to HRC58-62 and suitable for use with linear bearings and linear ball bearings. Linear Shaft Rod provides the most consistent surface hardness and depth of hardness across a range of sizes, offering increased performance. The consistent dimensional tolerances along the entire length of the steel shafting maximize consistent bearing operation.

Special Machining for Linear Shaft

1. For the Length 

We can offer linear shaft with diameterφ3mm-φ150mm. Maxium length up to 6000mm. 
When you are special requirements on length, we can meet your machining requirements with different length. 
When you request above 6000mm, we can anti-connect for you.

Linear Shaft Rod is case hardened to HRC58-62 and suitable for use with linear bearings and linear ball bearings. Linear Shaft Rod provides the most consistent surface hardness and depth of hardness across a range of sizes, offering increased performance. The consistent dimensional tolerances along the entire length of the steel shafting maximize consistent bearing operation.

Linear shafts are elongated, rod-shaped devices that provide linear or rotary motion for power transmission applications.Smooth, hard, and wear resistant, linear motion shafts work with linear bearings to reduce friction in manual and automated systems, such as those found in packing, machine tool, and material handling operations. The smooth surface reduces friction and wear on the bearing—the lower the microinch value a shaft has, the smoother its finish and the less friction it will create. All are turned, ground, and polished to tight diameter and straightness tolerances.

Mounting Options

Some linear shafts have axial or radial holes for mounting to support structures. Others are grooved for the placement of snap rings or channeled for keyways.

Specifications

Important specifications for linear shafts include shaft diameter or width, maximum length, weight, height, and tolerance.

Linear Shaft Hardness

There are several ways to measure the hardness of linear shafts.

The Rockwell hardness test presses a steel or diamond cone against a test sample and measures the depth of the resulting indentation. Higher measurements indicate harder materials. For linear shafts, common Rockwell hardness ranges are 50 to 59, 60 to 69, and 70 to 79.

The Brinell hardness test subjects a test material to a load of 3000 kg with a hardened steel or carbide ball that is 10 mm in diameter.

The Knoop hardness test also measures a material’s hardness through its resistance to indentation.

The Vickers hardness test indents a test material with a diamond indenter that is shaped into a right pyramid with a square base and an angle of 136° between opposite faces.

Linear Shaft Rod Application: 
1. Solid shaft
Generally applicable to industrial robots, as a professional measuring instruments, medical equipment, precision machine tools, aircraft shaft, pneumatic mandrel movement part. 
2. Hollow shaft
With its weight to reduce equipment, simplify the structure of the advantages, you can then wear the internal measurement of wire, compressed air, can also add lubricants and hydraulic oil. 
3. Stainless steel shaft
It's generally suitable for use as a part of the measurement in the presence of chemicals such as chemicals, seawater and other
Substances. 

Special machining shafts are finely finished after heat treatment with hard chrome plating for all types of automation equipment.
