Springs and pressings


Torsion springs

Great machine park for efficient work

Let’s (torsion) spring into action and start the Easter holidays! Torsion springs are very commonly used since they are very flexible and with great machine parks the springs can even be made in only one machine. No extra handling needed. That’s what I call efficient.

Belt tracking

Conveyor belt mistracking causes great problems. Now the US is focusing on different belt training methods to help prevent these mistrackings. Here torsion springs are used in safety mechanisms for detecting both forward and reverse mistracking.

Fat Bike Ski

Forget about slalom skiing or snowboard, here’s something completely new to me – Fat Bike Ski. Between this fork mount and the ski is a dual pivot urethane torsion spring, which allows the ski to smoothly follow trail pitch without being too flimsy—think of it as an artificial ankle on a skier. Talk about great engineering!


Game changer used spring for pedals

Clipless padels came in the 1980’s and was a real game changer for the market. A torsion spring replaced the earlier used belt on toe-clip pedals, which made it a lot safer to ride since the pedal detach if the you fell down.

Tablet with hides torsion springs in the base

When the tablet Surface Studio was launched last year it had a screen that weight 13 pounds but feels weightless. Now that’s job well done. You can’t see it at the moment but there are torsion springs inside the bar that attaches the screen to its base horizontally.

Shed some light on spring torque force

New week! Let’s make it a good one and start by shedding some light on what makes torsion springs so great. In technical terms we’re talking about the torque performance, in this case . Torque is equal to force x leg length: M= F x A. Torsion springs have a linear spring characteristic, i.e. if a spring is turned 10° to provide torque of 1 Nmm, the same spring will provide a torque of 2 Nmm at 20° torsion. Interesting!


Up and away!

Did you play with model airplanes as a child? I didn’t but my brother did. He’s airplane looked a bit like this one, but what I’ve just learned is that there are torsion springs at the wing tip end of the folding strut mechanism to provide tension in the lines. On some model airplane types , not all.

Spring controlled trip-edge

Gotten any snow yet? We haven’t got much but I keep the faith. Here’s a plow in stainless steel with torsion-spring controlled trip-edge. According to the manufacturer  these plows have chrome alloy wear bars for a longer cutting edge life.



For easier loading of trailer

Springs tend to have a very wide usage area. Here’s a great example where torsion spring is used on a trailer ramp to ease the loading process.
