Quick Summary
The Durock Dolphin 62g is a factory-lubed silent linear built around silicone dampers on the stem and slider rails, and it makes one thing very clear: this is about as quiet as a mechanical switch gets. If your priority is keeping noise down without dropping to a feathery 45g spring, the Dolphin is one of the most convincing silent options available. It suits office desks and shared spaces, and anyone who wants a smooth linear that stays quiet under normal typing.
Specs and Feel
This is a true linear: a clean, uninterrupted 62g stroke with no bump. Travel is short-ish at roughly 2.0mm to actuation and about 3.8mm to bottom-out, and the silicone damping on both ends of the stroke is what defines the experience. The downstroke lands soft and the return is the standout: muffled, controlled, and quieter than the well-known Cherry and Gateron silent reds it gets cross-shopped against. Out of the bag the POM stem moving in the polycarbonate-top, nylon-bottom housing feels genuinely smooth, with no notable scratch and well-controlled stem wobble. There’s a curious quirk worth flagging: despite the 62g rating, the dampened bottom-out gives the Dolphin a lighter subjective feel than its number suggests, so don’t assume “62g” means heavy here.
Tuning
There’s little to do. These arrive factory-lubed and play nicely with a range of keycap profiles, so most builders should run them stock. If you’re chasing the last sliver of spring ping, a light spring lube is the only worthwhile tweak. Films and stem lube aren’t necessary and risk muddying an already-clean feel.
Verdict
If quietness is the assignment, the Dolphin 62g is a strong pick. It’s arguably the quietest silent linear you can buy stock, and it’s smooth enough that you’re not sacrificing feel for the silence. The one caveat: the cushioned, light-feeling bottom-out won’t suit everyone, especially if you like a firm, defined stop or you’re mixing silents alongside heavier tactiles. For a quiet office board or a smooth all-day linear, though, it’s hard to do better.
Frequently asked
Is the Durock Dolphin 62g really that quiet?
Yes. Silicone dampers on the stem and slider rails cushion both the downstroke and the return, and the muffled upstroke in particular is where the Dolphin pulls ahead of most other silent linears. It is one of the quietest stock switches available, which makes it a strong choice for shared offices and late-night typing.
Does the Durock Dolphin 62g need lube?
No. It ships factory-lubed and feels smooth straight from the bag. You can lightly hand-lube the springs if you want to chase a touch of ping, but most builders will be happy leaving these stock.
How heavy does the 62g spring feel?
On paper it is a medium-weight linear, but the silicone damping gives it a cushioned, almost lighter-feeling bottom-out. It lands in comfortable all-day territory rather than feeling heavy.
