Low backlash planetary gearboxes
Bonfiglioli spare parts TQ - Precision planetary gearbox

The TQ series of low backlash planetary precision gearboxes is designed to deliver the highest possible level of transmission precision. Low backlash combined with a high torsional stiffness guarantees a very competent product, especially in high dynamic and reversing applications.
The technical design of this gearbox also allows high axial and radial loads on the output shaft and a very silent operation.

TQ features two classes of precision, corresponding to the following values of circumferential backlash
1-stage units: standard φs ≤ 3’ reduced φR ≤ 2’ (φs ≤ 4’; φR ≤ 2’ for TQ 060 and TQ 070)
2-stage units: standard φs ≤ 5’ reduced φR ≤ 3’ (φs ≤ 6’; φR ≤ 4’ for TQ 060 and TQ 070)
