Planetary gearbox Ultimate RA series

helical gearright angle200 - 500 Nm

EXTREME DUTY CYCLES WITH HIGH LOADS APPLIED ON THE OUTPUT FLANGE Ultimate is a heavy-duty, low-backlash planetary gearbox. It features considerable stiffness and amazing acceleration capacity, together with extreme load capacity on the output flange. Acceleration capacity+++++ Fast reversals+++++ Radial load rating+++++ Axial load rating+++++ Stiffness+++++ Precision++ Economy+++ Suitable to servo-motor applicationsYES Number of sizes in this line4 (64 to 140) Standard angular backlash<3 or <5 arc-min Optional reduced backlash<1 or <3 arc-min Available ratios4 to 100 Motor shaft connectionBalanced coupling Ultimate RA is a heavy-duty, right-angle, low-backlash helical planetary gearbox. The planet carrier is a massive cage providing stiffness and acceleration capacity. It is monobloc with the output flange. The cage is centered into the inner planetary ring by means of 2 preloaded angular-contact ball bearings (for small sizes) or tapered-roller bearings (sizes above 140). This construction reinforces the acceleration capacity and the gearbox acceptance of fast reversals. We recommend this line for applications using application factor Ka<2.25 (refer to the information section for more details about application factors).
