Height critical? The FMB bearing solves precision rotary positioning problems

The FMB bearing from Micromech is the ultimate in low profile, high precision rotary bearings ideal for positioning systems where both precision and height is critical. The various bearings sizes are only 8.5 to 12.5mm tall yet deliver radial and axial run-out from 10 microns down to 1 micron and wobble from 6 down to 2 micronrads.

The very thin and compact precision bearing is a turntable bearing designed to provide high performance circular motions in as small a package as possible. The bearings are currently available in 9 standard sizes with OD’s ranging from 120 to 350mm and ID’s ranging from 40 to 250mm and for OEM applications, custom sizes are available up to 500mm OD to exactly match the application. They can support axial, radial and moment loading, have high rotary precision and repeatability, and provide significant cost savings up to 50% of classic turntable versions.

Classic turntables are designed by using a double pack of bearings which are often complex making them costly as they use more components and also assembly must be done by trained workers. The FMB design is much simpler with just one bearing having only one inner and one outer ring thus achieving significant cost savings.
