Linear shafts
Linear shafts are used in various industries and applications. What is particularly interesting about the MISUMI linear shafts are the different designs that they are available in. You can configure the MISUMI linear shafts in our online shop according to their specific application and your own specific requirements. We then produce the chosen product for you according to your specifications and deliver it to you. This eliminates the need to create the single part drawing and the conventional steps of in-house and contract manufacturing.
The MISUMI online shop offers the following configurations for linear shafts:
- Shaft length to choose from: 10 to 1500 mm
- Shaft diameter to choose from: 3 to 100 mm
- Various end forms: straight, conical, internal thread, external thread, adjustable screw groove, spring groove, circumferential groove, hexagon socket
- Material to choose from: various normal and stainless steels (1.3505 equiv., 1.4125 equiv., 1.1191 equiv., 1.4301 equiv.)
- Various surface treatments: untreated, chrome-plated, black chrome-plated and nickel-plated
- Different shaft designs: complete (without end machining), complete and lowered on one side, complete and lowered on both sides, hollow (without end machining) hollow and lowered on one side, hollow and lowered on both sides
- Dimensional tolerances to choose from for fits: various dimensional tolerances f8, g6, h5, h6, h7 and k5
Linear shafts in powertrain production
Efficiency, precision and reliability: Three factors that are of particular importance in powertrain production. Components are ultimately produced for millions of vehicles that will play a leading role in vehicle safety. The powertrain components produced include axles, drive shafts, brakes, transmissions, engines and shock absorbers for cars and commercial vehicles. Linear shafts are a machine element that is used very frequently in powertrain production. They are used as a linear guide in that they are subjected to forces that generate a bending moment, but do not transmit torque. They are mainly used as a guide shaft combined with linear ball bearings and plain bearing bushes. The shaft bearing is usually achieved with a fixed and a floating bearing.
Linear shafts are characterised by their outstanding reliability, durability and low maintenance. This makes them a frequently used machine element.
IBK Herzog leakage jig: Sample application
The exact practical use of products is shown in the example of the IBK Herzog leakage jig. A total of 6 linear shafts with double-sided internal thread were used in this case. Linear shafts often form a lift mechanism in conjunction with a hydraulic or pneumatic cylinder and ensure the horizontal and vertical lifting movement.
IBK Herzog tests the tightness of a housing with this device. This device is designed for leak tests with compressed air. A workpiece carrier is used to transport the housing to and from the testing area. The workpiece carrier is lifted into the testing area with a pneumatic mechanism, the sealing head is then driven manually to the housing in order to keep it in place and to close each of the vertical holes. Horizontal holes are then sealed with a clamping mechanism. MISUMI linear shafts are used in order to ensure an exact guide during the sealing operation.

Contact switches have been used in automotive manufacturing for some time. The METROL ultra-precision position switches can operate with high accuracy – even under harsh working conditions where the refrigerant and chip cuttings spray. This means they are ideally suited for powertrain production. |
