PM Bearings and The Precision Alliance proudly introduce the ULTIMATE in low profile, high precision rotary bearings. The FMB Series is ideal for rotary positioning systems where both precision and height are critical.
The various bearings sizes are only 8.5 to 12.5mm tall yet deliver radial and axial run-out from 10µm down to 1µm and wobble from 6µrad down to 2µrad.
FMB bearings... Accuracy in a Smaller,Simpler, Package
The FMB is constructed of high quality bearing steels, PTFE filled, plastic ball cage and super precision steel balls. The specially designed raceways increase load capacity and stiffness while guaranteeing high precision, long life, and a low coefficient of friction.
There are 9 standard sizes with OD’s ranging from 120mm to 350mm and ID’s ranging from 40mm to 250mm. Each size has different precision grades and preload classes. Additionally, for OEM applications custom sizes are available up to 500mm OD to exactly match the application.
The FMB Series is also very easy to apply. Most rotary bearings fit into a bore which must be very precise to avoid deforming the bearing and spoiling the precision. The FMB includes a 0.5mm offset between the inner and outer races and counterbored holes to enable mounting directly onto flat surfaces.
FMB flat mounted bearings are manufactured in two quality grades (N)ormal and (P)recision grade and are supplied by default with zero clearance.
The Precision Alliance is a Global Sales and Marketing Alliance between a few, relatively small companies that have aligned themselves to provide a complete miniature product offering to the automation industry. The Precision Alliance has been established to answer the ever-increasing demand for higher precision and lower costs. Our combined product offering provides designers with the widest variety of components for miniature automation tasks, and our ability to provide complete subassemblies at both ends of the accuracy spectrum answers the increasing demand for cost effective positioning solutions from a single source.
