New product: sealed GB12 gearbox

British motor manufacturer, Parvalux EMD, has launched a fully sealed version of the GB12 square-framed, worm-wheel gearbox.

In preventing contamination of the gears and housing by the ingress of fluids or particulates, the completely sealed design facilitates an estimated life expectancy of over double that of similar half-seal worm and wheel design; offering customers double the reliability of many competing and legacy counterpart products.

The unit comes with a choice of 9 standard DC commutated permanent magnet motors from Parvalux's EMD application range, or can be customised it to fit any one of Parvalux's other standard AC or DC motor products.

Features include:

* Maximum continuous torque of 45 Nm

* A choice of 6 reduction ratios (12.5:1, 25:1, 30:1, 50:1, 60:1, 75:1)

* Composite or phosphor-bronze gear . Ingress Protection rating IP65

* Steel output shaft diameter up to 25 mm (single or double) . 2 year parts warranty

* Sealed aluminium housing

* Black finish option

The GB12 shares the same dimensions and fixings as the popular EMD-GB4 unit, designed originally for wheelchair and golf trolley applications, but now used in a myriad of other applications throughout the mobility, leisure and industrial sectors. Customers seeking to replace old GB4 motor-gearbox units therefore are being encouraged to consider a GB12 solution for extended reliability.
