LUK is an OEM Flywheel manufacturer for BMW. 

LuK dual-mass flywheels absorb engine vibrations before they are transmitted to the driveline where they can create gear rattle.

These units feature a built-in damper designed to isolate engine torque spikes and prevent transmission damage. By design, dual-mass flywheels cannot be resurfaced.

This all makes the LuK dual mass flywheel the ideal solution.
With one drawback: the higher the mass reactance of the vibrating masses, the more excessive the resonance increase and associated torque peaks. With the dual mass flywheel, this would be easily perceived when starting and stopping the engine; much more easily than with a conventional clutch system. Additionally: the smaller flymass of the engine has less of a stabilizing effect on the speed fluctuation of the engine.

Thanks to decades of experience in clutch building, the LuK specialists were able to find an excellent solution to this problem. An additional damping device effectively prevents resonance overload. In normal operation, however, this additional damping device has no function and the torsional vibrations of the engine are filtered out by spring dampers. 

Friction and spring rate - the correct ratio is important.
For optimal vibration isolation and soft resonance passage when starting and stopping the engine, the ratio between friction and spring rate must be optimal. The length of the springs is a key factor: The softer a spring, the more efficiently vibrations are isolated. The extra-long springs of the latest generation of dual mass flywheels significantly reduce the spring rate compared to a first generation dual mass flywheel. In routine driving operations, excessive resonance increases are kept almost completely away from the gearbox.

Features and Benefits:

  • Top driving comfort
  • Absorbs vibrations
  • Prevents noise
  • Enables comfortable, low-revs driving
  • Saves fuel
  • Relieves crankshaft and gearbox

    Super Satisfied Customer Here!
    Color: Gold, Color: Gold
    I purchased the gold/black mug warmer. I always spend a good about of money for great coffee products and I take my time to perfect my coffee for my mornings at work. However, I get pulled into urgent meetings and just something urgent and I always leave more than half of my coffee behind. When I come back it’s cold and that’s very disappointing considering the money and time I spent to make it bc I then have to toss it. I don’t believe in microwaves and I refuse to use one. When I found this, I was super excited! It looks perfect at my desk and it works perfect! I would have liked it to be more on the brass gold like my pen holder, but it’s just as pretty! As you can see, my mug had a layer on the bottom and that made me think it may not work well, but it did the job. My coffee was super warm and it got even hotter as I left it there tearing it. I turned it one before making my coffee, so I’m not sure exactly how long it took to warm up but for me, by the time I got back, it was the peg temperature. I highly recommend this to anyone who has the same struggles. No more cold coffees! Thank you!!!

    Neat gadget
    Color: Gold
    Neat little gadget. Works great, easy to use and has a light indicator for temperature range. Keeps a cup of liquid hot right to the bottom.

    My tea stays warm to the bottom of the cup!!!
    I am so glad I purchased this mug water. I drink tea all day but it cools down quickly. Since I purchased this mug warmer my tea stays hot to the bottom of the cup. The temperature is adjustable so you can keep your drink at your desired temperature. The top is glass and wipes clean easily. I like the rubber gasket that fits on top of the warmer. It keeps your mug in the center of the warmer and should you have a spill it catches the liquid. I've been using it every day for over a month now and it's going strong and is reliable. Perfect for personal use or as a gift.

    Keeps my coffee as hot as I want it to be
    Color: Silver
    This coffee warmer is much better than the candle warmer that I was using for my coffee before. With a range of 3 temperatures, I have a choice of temperatures from hot to very, very hot, and the warmer shuts itself off after a while, just in case I forget. The description advises that ceramic cups do not retain heat as well as flat-bottomed cups, but I have not found that to be a problem. Coffee in my ceramic mug stays as hot as I want it to be. The knob on the side makes this warmer easy to turn on and to select a temperature, plus I feel that it is a good value.

    Perfect Mug Warmer
    Color: Black
    I bought this to replace one I'd had for more than 25 years & I'm glad I got this one. Keeps my hot drinks hot for hours & will shut off after that. Quickly heats back up when needed. Very sleek looking. Easy to set up. Just take it out of the box & plug it in.
