SKF hardened precision shafts
All SKF precision shafts are available in different diameters and lengths. The solid shafts that we offer are all solid shafts. SKF shafts ave exceptionally high dimensional stability and are designed for long service life. It is important to use the right type of material shaft for a given application. Therefor it is possible to choose from three different kinds of non-alloyed high-grade steels. For all the shaft types, it is possible to supply them with certain modifications. This may be by means of frequently used modifications or with personal modifications, based on your technical drawing. You can find an explanation of these different modifications at the bottom of the page.
If you need advice on the type and implementation of the bearing (unit) that is most suitable for your problem, we would be glad to help. During working hours you can contact us on the following number +31 (0)85 – 0661258.
The SKF hardened precision shaft LJM is a solid shaft of high-quality hardened steel (CF53). this shaft can therefor withstand high pressures without deformation. The LJM has a hardness between 60 and 64 HRC (Rockwell Hardness Scale). The maximum sufrace roughness is Ra 0,3 μm. The LJM is available in sizes between 6 and 80 mm.
Deviating tot the LJM, the SKF hardened precision shaft LJMR is available in sizes between 6 and 50 mm. The solid LJMR shaft is made of high-quality hardened stainless steel (X90CrMoV18). The hardness of the LJMR lies between 54 and 57 HRC (Rockwell Hardness Scale). This shaft as well has a maximum surface roughness of Ra 0,3 μm. The LJMR is ideal for applications where possible contact with a large number of products including steam, petroleum and alcohol may occur.
The SKF hardened precision shaft LJMS is made of high-quality hardened stainless steel (X46Cr13). With this solid shaft, this results in a hardness between 52 and 55 HRC (Rockwell Hardness Scale). If the shaft may come into contact with fresh water, dilute acids and alkalis, fruit and vegetable juices, this is the shaft that you need. The SKF LJMS shaft comes in sizes between 6 and 50 mm. The maximum surface roughness of the LJMS is Ra 0,3 μm.
For all shafts a dozen modifications are possible so that you will receive the proper shaft. In addition, it is also possible to manufacture the shaft according to your specific needs and drawings. Below the nine modifications are explained, if you would like a tailer-made shaft please contact us on +31 (0)85 – 0661258
