Super-precision axial-radial cylindrical roller bearings are commonly used to support rotary tables, indexing heads and multi-spindle heads on machining centres. Prius manufactures super-precision axial-radial cylindrical roller bearings for shaft diameters from 80 to 850 mm. Their internal design, together with close tolerance manufacturing processes, enables these bearings to attain radial run-out better than, and axial run-out close to, P4 tolerance class.
Axial/Radial Bearings
Axial/radial bearings YRT, RTC and YRTSpeed and axial angular contact ball bearings ZKLDF are ready-to-fit high precision bearings for high precision applications with combined loads. They can support radial loads, axial loads from both sides and tilting moments without clearance and are particularly suitable for bearing arrangements with high requirements for running accuracy, such as rotary tables, face plates, milling heads and reversible clamps.
Due to the fixing holes in the bearing rings, the units are very easy to fit.
The bearings are radially and axially preloaded after fitting.
The mounting dimensions of all series are identical.
