Stainless steel linear modules

Corrosion-free and chemical resistant

Wherever lubrication must be dispensed with and where machine components are in contact with food, strong cleaning agents or even chemicals, stainless steel is necessary. T

o minimise maintenance and cleaning effort, igus® has developed linear modules and linear axes for just this scenario - drylin® linear axes made of stainless steel.

Technical options for the SHT series

The following options can be configured directly online for the SHT product range.

drylin lead screw material and lead screw design

Lead screw design

All drylin® SHT-ES linear modules are delivered with self-locking trapezoidal lead screws made of stainless steel. Hard-coated aluminium is also available upon request. The series can also be configured with stainless steel high helix lead screws (optional). This allows much higher pitches and drive speeds, but without the self-locking feature.

    Electric drive systems: electric motors from igus

    Whether DC, lead screw stepper or EC/BLDC motors: with its wide-ranging motor shop, igus offers the possibility of equipping linear axis systems with the appropriate motor solutions. In combination with drylin linear axes, which can be ordered completely ready for installation and connection, entire handling systems can be configured. With the powerful motors you solve a wide variety of problems in electric drive technology.

    Bearing materials

    All drylin® drive units bearing points are equipped with lubrication-free­ and maintenance-free igus® high performance polymers. Options include materials for high-temperature applications up to +180°C (iglidur® X, SHT­ES series), and for FDA-­compliant environments (iglidur® A180).

    Hardened stainless steel
    Linear axis guides of hardened stainless steel are usually offered in combination with recirculating ball bearing systems and roller bearing guides. The guide system's metal balls require a strong running surface to prevent them from creating grooves. Hardened stainless steel such as AISI 420C, AISI 440B and AISI 440C has a relatively high carbon content (more than 0.5%), which is necessary for hardening in the first place. This means that hardened stainless steel is only somewhat corrosion-resistant. The necessary lubrication for recirculating ball bearing systems and roller bearing guides entails a danger of contaminating products, which is undesirable in many areas.

    Non-hardened stainless steel
    Non-hardened stainless steel has a lower carbon content and inferior hardness, but is much more resistant to corrosion and aggressive cleaning agents and chemicals. Because recirculating ball bearing systems and roller bearing guides are not as well suited to moving on non-hardened stainless steel, a plain bearing system is used. The force exerted at particular points on the rail material is changed to area force. The load on the linear rail is distributed across a greater area, avoiding material wear.

    The principle: "sliding instead of rolling"

    The advantages of plain bearing liners over a recirculating ball bearing system


    The high-performance polymer plain bearing liners used by igus need no lubrication or maintenance and are ideal partners for stainless steel linear modules. The combination of plain bearing system and stainless steel linear axis is used in certain applications because of the advantages of linear drive systems.
