      [!] Low temperature black chrome plating is not applied to the inside of hollow shafts, taps, bored holes and lateral holes, etc. Therefore, they may rust.
      [ ! ] Annealing required for wrench flats machining and shaft end threading (effective thread length + approx. 10 mm) may lower hardness.
      [ ! ] Machined areas may be out of O.D. tolerances due to annealing-induced deformation.

      ■About hollow shaft wall thickness deviations and internal diameters

      Depending on the material, hollow shafts will vary in wall thickness deviation (A–B) and internal diameter (d).

      Notes on Hardening and Surface Treating

      ■Reduced Hardness around Machined Areas

      ·Although processing is performed after the base material is hardened, annealing may lower hardness of the machined area.
      * Reduced Hardness: Approximately 10 to 40 HRC

       

      ■Reduced Hardness Range

      ·Approximately 10 mm from the machined area

      (Example)
      Hollow Shaft - One End Stepped, One End Tapped Hollow Related Image 1_Reduced Hardness Range
       

      ■Machining area where hardness has lowered due to annealing

      ·Stepped, Wrench Flats

       

      ■Effective Hardened Layer Depth of Hardening

      The effective hardened layer depth varies depending on the external dimensions and materials.

      O.D. DEffective Hardened Layer Depth

      25 to 501.0 or More
       

      ■About hard chrome plating and plating layer of processed part

      • Hard chrome plating is applied after surface treatment of the base material, so there is no plating on the processed parts.
      • In the example below, only "///" area is treated with hard chrome plating.

      * Hollow shaft interior surfaces are not plated. Therefore, they may rust.

      Surface Limits / Hardness - Linear Shafts

       

      Limits of hardness and hardening depth

      The linear shafts are processed after the base material has undergone inductive hardening. Therefore, the processed surfaces may result in a deviating hardness.
      In the following example, you can view the affected areas of the linear shaft, which may be affected after processing by e.g. threads, level surfaces, key surfaces and transverse bores.

       

      Limitation of linear shaft induction hardening

       

      Cause for deviating hardness

      The raw material of the linear shaft is treated via thermal induction before grinding. Thus, a configured linear shaft can be custom-made not only cost-effectively, but also with short delivery times. The linear shaft is hardened at the boundary layer (boundary layer hardening) of the liner shaft. The depth of the hardened boundary layer depends on the material used and the diameter of the linear shaft. The following table shows the hardening depth of linear shafts.
      Coatings and plating are applied to the raw material after hardening and grinding. For more information, see Coatings of the Linear Shaft.

      Coatings of the linear shaft

      The surface coating is applied to the raw material before machining the linear shaft. Thanks to their coating, the usable surface or work surface of the linear shaft is not only protected against corrosion but also against wear.
      Machined positions of the linear shafts, such as plane surfaces or threads, may be uncoated, as they are added afterwards. This can lead to the machined surfaces being corroded in a linear shaft made of steel. If the linear shaft is used in a corrosive environment, it is recommended to use a stainless steel linear shaft.
      The following figure shows the areas of the linear shaft that are coated (crosshatched).

      Description / basics of the linear shaft

      Linear shafts are steel shafts that perform guiding tasks in combination with linear bearings, such as plain bearing bushings or linear ball bushings. Linear shaft holding functions can be adopted from shaft holders or linear ball bearing adapters. Most linear shafts are heat-treated (induction hardened) solid shafts. A special design of linear shafts is the hollow shaft, which is also called tubular shaft. Inductively hardened linear shafts have a high surface hardness and a tough core. The achievable surface hardness is approx. 55-58 HRC (see information on hardening depth). Linear shafts made of stainless steels can generally not be hardened. Therefore, these steel shafts should be chrome plated to protect them from wear.

       

      Materials

      Linear shafts are mainly hardened steel shafts. In addition to the selected heat treatment, the steel used in particular imparts its properties to the linear shaft, although it is a hollow shaft or a solid shaft. Therefore, special aspects such as hardness, corrosion and wear must be considered when selecting the shaft steel.

       

      Coatings

      To protect linear shafts from corrosion, the surface can be chemically nickel-plated. As an alternative to chemical nickel-plating, steel shafts can also be coated with LTBC. The LTBC coating is an anti-corrosive surface coating and it is a low-reflection coating, made of a 5 μm thick film of fluoropolymer, which in essence is a black film. In addition, the LTBC coating is resistant to bursting pressure by extreme or repeated bending. LTBC-coated linear shafts are thus particularly suitable for locations where corrosion or light reflections are undesirable. Linear shafts that require particularly high surface hardness and wear resistance can be hard chrome plated.

       

      Function

      The form and function of linear shafts differ from linear guiderails. Linear guiderails are square rails that work in combination with carriers (rotary elements, carriages) according to the rolling or sliding principle. Linear shafts on the other hand are precision-ground round steel shafts that take on a linear guide function in conjunction with linear ball bushings or plain bearing bushings (maintenance-free bushings).

       

      Areas of Application

      Linear shafts are intended for axial motion. Whether horizontal or vertical linear motion, all linear motions can be implemented with linear shafts. Common applications are stroke mechanisms and other applications with high demands on smoothness, precision and service life. Linear shafts can therefore be used in almost all industries of plant construction and mechanical engineering. Linear shafts are often found in 3D printers, metering equipment, measuring devices, positioning devices, alignment devices, bending devices and sorting equipment.

       

      Instructions for Use / Installation  - Linear Shafts

       

      For product selection, please observe the linear shaft tolerances (e.g. h5, k5, g6, h6, h7, f8) in conjunction with the diameter tolerance of the plain bearing bushing (sliding bearing) after pressing in or the running circle diameter of the linear ball bearing (ball bushing).
