<p>What grease to use on linear rails to make them stick as little as possible? I've tried so far: </p>

<ul>
<li>WD40 (let’s not start a discussion about that please), </li>
<li>silicon spray and </li>
<li>some bearing grease called ‘motorex’, </li>
</ul>

<p>but with all of them the rails stick quite much and don’t slide as easily as I’d hope.</p>

<p>Can someone recommend some good grease for linear rails (specifically the hiwin type, 12-15mm)?</p>
