Silicone Bumpers - Large (10x16.5mm, 4 pack)

Rubber feet raise your PCB or project up off your desk. This helps prevent short circuiting from bits of scrap wire floating about or setting a project down on a conductive surface. They also prevent your enclosure or PCB from sliding around. They can also be used as feet for enclosures. These are self-adhesive and 16.5mm in diameter and about 10mm tall. They taper to roughly 12mm at the top. They come in a set of 4.

    These are Free?

    You should mention the "Silicone Bumpers - Small" ( 8x2mm, 4 pack, sku: PRT-10230, ) below.

      Thanks, that was just what I was looking for! I second the motion!

    these are some nice,cheap,stiff silicon feet/bumpers. perfect for enclosures but perhaps a bit to large for most PCBs.
    i myself use a set of these as bumpers for when one of my little projects run into the wall....again

    These are lovely but I find that the adhesive fails. Maybe you can get ones with a screw mount?

    • I've generally found this adhesive to be ridiculously....adhesive. What kind of applications do you notice it failing? High temps, certain positions, humid environment, anything like that?

    SOLD OUT, WHY!?! These are really nice bumpers. They are very large though, so they will not fit on most PCBs. I used them on my large proto-breadboard.

    To any Materials Science and Engineering people who have seen these: What's the Young's Modulus of these bumpers?
    This is totally a serious question. If the Young's Modulus is high, then these aren't squishy, but if the Young's Modulus is low, these behave like marshmallows.
    I'm considering using them as risers for my laptop, which gets to about 80C (yeah, Celsius) underneath. If they're really squishy, then they couldn't support my laptop, and the laptop would simply sag down onto the table again.
    Edit: Or I could have just asked: How stiff are these?

    • pchalla90 / about 13 years ago / 1

      Eh. I ordered them anyway. I received them today. In case anyone else was wondering, it's pretty stiff. The Young's Modulus would be more in the range of hundreds of MPa rather than low MPa or even KPa.

    I'm sorry. You've named this item incorrectly. I've always referred to these as Little Rubber Feet, or LRFs for short. Please be sure to fix this egregious error in nomenclature. ;)

These are great!

I bought them for a project I was putting in a standard project enclosure and they worked perfectly.

I then noticed that my keyboard was sliding all around on my glass desk because the rubber feet had come off. I put two of these on the bottom of the keyboard (I was a little afraid they were too tall) and they worked like a charm to keep it in place.

Works perfectly! Adhesive is great!

Will definitely buy more in my next order!
