Rotary Bearing

Rohit Bearing proudly introduces the ultimate in low profile, high precision Rotary Bearing. We have carved a niche as one of the prominent manufacturers of Rotary Bearing. The Low-Profile Rotary Bearing 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. The Bearing 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 High Precision Rotary Bearing 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 Bearing includes a 0.5mm offset between the inner and outer races and counter bored holes to enable mounting directly onto flat surfaces.
