Spindle gearboxes of high robustness

For linear motions with larger loads, BJ-Gear A/S offers the spindle gearbox.
A BJ-spindle gearbox is very robust in terms of overload and operating environment.

The design is compact, simple and its modular construction allows great flexibility in the choice of gear, mounting options, flanges, oil types and surface treatments. The modular design is also ideal if there is a need for customisations where the gearbox must be optimized for specific needs. That is the reason why we can produce spindle gearboxes adapted to your wishes at an attractive price.

The BJ spindle gear
box is basically in four versions:

The spindle gearbox allows for axial positioning and together with our other products within the field of encoders, couplings and connecting shafts, it allows for running more axial movements synchronously.


The spindles can be protected from dirt and water by using protecting tubes.

All spindle gearboxes may as standard be supplied with easy-to-clean and yellow chromated surfaces with stainless steel spindles and food approved lubricants.
If there are special requirements for the design, we are pleased to offer adaptations even in smaller quantities.

The BJ spindle gearbox is designed in a number of different versions and is currently used in countless solutions within Healthcare, the Food Industry and other industries.

Spindle gear with trapezoidal spindle

The spindle gearbox is primarily used where there is a need for relatively slow axial speed and/or where the compact design of the worm gearbox can be an advantage. A standard spindle gearbox with trapezoidal spindle ensures a tensile/compression force of up to 40,000 N and linear speed of up to 2,800 mm/min. If there is a need for higher speed and/or loads, we have a great experience in adapting or designing special spindle gearboxes. The spindle gearbox is always self-locking due to the trapezoidal spindle, which in many cases may constitute an additional safety factor, for example, when the spindle gearbox is used for lifting tables.

Spindle gearbox with ball screw spindle

Spindle gearbox with ball screw spindle provides advantages over the trapezoidal spindle in relation to efficiency, speed, precision and running time.

By using a standard spindle gearbox with ball screw spindle, you can achieve linear speeds of up to 20,000 mm/min. If there is a need for higher speed and loads, we have great experience in adapting or designing special spindle gearboxes.

Since the ball screw spindle has a very high efficiency, it will limit the accumulation of heat in the spindle and nut. Therefore, the ball screw spindle is suitable for continuous operation.
