Non-magnetic Components with High Hardness and Precision
Special alloy for high-performance bearings resistant to magnetization
THK-NM1 is a non-magnetic special alloy that has the degree of hardness necessary for bearings. Products made from this alloy offer excellent load rating, high precision, and low-friction motion in environments that require non-magnetic properties. It is also highly corrosion-resistant being comparable to titanium alloys.
THK offers the special alloy for almost its entire product range. These include linear guides (linear guideways), ball screws, ball splines and cross roller bearings.
Excellent non-magnetic characteristics
The relative permeability of THK-NM1 is less than 1.005. It is almost completely resistant to magnetization and is therefore ideal for use in strong magnetic fields.
Excellent load ratings
Through a special heat treatment, these bearings achieve a suitable hardness with a far higher load rating than bearings made of non-magnetic, austenitic steel. Applications can thus be constructed more compactly overall since the use of smaller components is possible.
Low-friction, high-precision movements
The material characteristics of THK-NM1 allow the application of a preload. The result is low-friction, backlash-free movements with high precision.
The magnetic field in the MRI scanner has no negative impact on the smooth-running characteristics of the linear guides.
There is no magnetization that could deflect the electron beam. Therefore, the beam can hit the sample accurately and generate a precise image.
