Axial-radial bearings AL-RT 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.
Suitable for low speeds and small operating durations
Very high tilting rigidity
High axial-radial load capacity and precision
Dimensions and Tolerances
The boundary dimensions of AL-RT bearings are not standardised. ALPHA Wälzlager GmbH supplies axial-radial bearings with dimensional P5 tolerance and P4 running precision in accordance to DIN 620-3 and ISO 199. Please contact our technical department to check the availability of bearings with special tolerances.
The bearings are radially and axially preloaded after fitting. Preload is dependent on the mounting fits, the geometrical accuracy of the adjacent parts, the temperature difference between the inner and outer ring, the screw tightening torque and mounting situation.
