Linear shaft features

 Linear shaft description

ERSK Linear offers linear shafting in a variety of different options to meet a wide range of customer needs.  Available in hardened steel, CK45 material steel, SUJ2 material steel, hollow steel , inch and metric, Simplicity Shafting maintains the ideal surface finish for linear plain bearings and ball bearings.

· Solid round shafting is available in inch sizes from 3/16” thru 4” and metric sizes from 3 mm thru 80 mm

· Machining available upon request

High Reliability

ERSK linear shaft has very straight quality control standards covering every production process.  With proper lubrication and use, trouble-free operation for an extended period of time is possible.

Smooth Operation

The high efficiency of linear shaft is vastly superior to conventional shaft. The torque required is less than 30%. Linear motion can be easily changed from rotary motion.

High Durability

Rigidly selected materials, intensive heat treating and processing techniques, backed by years of experience,have resulted in the most durable linear shaft manufactured.

Induction linear shaft,  Flexible linear shaft,

linear bearings shaft,   hollow linear shaft,

hardened linear shaft,  chromed linear shaft

Application

For delicate application in industrial application, machine tool and automation application.

Linear Shafts – Technical Properties.

	Test linear shaft surface roughness the max roughness is Ra0.4um
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 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.

We can machinize all kinds of machining,
