Torque limiting knobs

Torque limiting knobs

Elesa torque limiting knobs are suitable for use across a range of industries. They provide safe and efficient tightening when the manually applied torque is to be limited. These products are commonly used on laboratory machines, key duplicators, tools for sharpening blades, and sports equipment.

Alongside our standard components, our range includes adjustable torque limiting knobs and wing torque limiting knobs. Our limiting knobs work by the torque does not exceed a certain value during application. The transmission of the torque from the knob to the clamping element takes place by means of a spring system which, upon reaching the required torque, releases the knob. We design our products to be simple to use. When operating, you will be able to hear a clicking noise when the establish torque is exceeded. This indicates that maximum tightening has been achieved. To unlock the Elesa-patented mechanism, simply turn the knob anticlockwise.

We pride ourselves on supplying components of varying specifications to meet a wide range of engineering needs. Within our catalogue you will find limiting knobs with threaded screw types of M5, M6, and M8. The component hole sizes are categorised as M5, M6, M8, M10 and M12.

The external diameter of our knobs is a range of:

  • 50mm
  • 60mm
  • 80mm

Our range is made from high-quality steel and technopolymer to provide components that are hard-wearing, durable, and easy to clean. Our technopolymer torque limiting wing knobs are available in a matte finish of orange or black. This results in a product that not only works exceedingly well but is appealing to look at. With a burst of colour, you can improve the appearance and aesthetic value of your machinery.

Our products undergo rigorous testing to ensure they are top performers, and our torque limiting knobs have been tested up to sixty thousand tightening cycles with exceptional results.
