SKF hardened precision shaft LJMR52 - 56 HRC | 12 en 50 mm
The SKF hardened precision shaft LJMR is a solid shaft of stainless steel (X90CrMoV18 quality). This shaft can therefor withstand high pressures without deformation. The LJMR has a hardness between 54 and 67 HRC (Rockwell Hardness Scale). The maximum sufrace roughness is Ra 0,3 μm. The LJMR is machined to h6 or h7 tolerances. Thanks to stee stainless steal 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 LJMR is available in sizes between 12 and 50 mm. For each size there are a dozen different modifications possible, to make sure that you get the right shaft. It is possible to modify these shaft tailer-made, based on your technical drawings. If you are unsure which modification is the most suitable, the differences are indicated below.
