The design of the BJ worm gearbox is simple and well proven. We only use high quality components such as houses in cast iron, aluminum and stainless steel, worms in case hardened and polished steel and worm wheels in high-grade bronze of special alloys ensuring the optimum wearability. The seals of the worm gearbox are provided with a dust lip which effectively resists dust and water. In addition, the gearboxes are greased for life with synthetic oil.

Low noise
Our worm gearboxes and actuators are extremely quiet. This is due to the very smooth running of the worm gear combined with the use of cast iron and high precision on component manufacturing and assembly. In connection with our precision gearboxes, we take extra care of any sound that can be interpreted as a murmur from the gear. So the general noise level of our gearbox is reduced to an absolute minimum.

Angular gearboxes
The input shaft and output shaft on the worm gearbox are perpendicular to each other. This often proves to be a decisive advantage making the incorporation of the gearbox considerably simpler and more compact. The worm gearbox is an angle gear. This is often an advantage for incorporation into constructions.

Strong bearings in solid housing
The output shaft of the BJ worm gearbox is very firmly embedded in the gear house and is ideal for direct suspension for wheels, movable arms and other parts rather than having to build a separate suspension.

Atex approved
Our standard worm gearboxes are approved for Zone 2 and 22, but we offer to supply all our products in zone 1, 2, 21 and 22 according to the requirements. Read more

Self locking
For larger gear ratios, BJ-Gear's worm gearboxes will provide a self-locking effect, which in many situations can be used as brake or as extra security. Also worm gear screw jacks with a trapezoidal spindle are self-locking, making them ideal for a wide range of solutions.
