drylin® SHT stainless steel linear actuators

Robust, corrosion-free and resistant to chemicals

Wherever lubrication must be dispensed with and machine components contact food, strong cleaning agents, or even chemicals, stainless steel is necessary. To minimise maintenance and cleaning effort, igus has developed linear modules and linear axes for just this scenario – drylin® linear axes made of stainless steel.

Typical application areas:

  • Food and bottling industry
  • Yacht building
  • Chemical industry
  • Medical technology
  • Packaging industry
  • Vending machinery

Not all stainless steels are the same

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.

drylin® lead screw stepper motors for linear axes

For motorised lead screw drive of the linear module, igus offers powerful lead screw stepper motors. The motors are available in three installation sizes: NEMA11, NEMA17 and NEMA23. The combination with a dryspin lead screw guarantees precise centring and a long service life of the entire linear module.

  • Three installation sizes with or without strand
  • Available ready to connect
  • With or without encoder
