Gateron CJ Dark Blue 50g

Quick Summary

The Gateron CJ (short for China Joy) Dark Blue is a medium-weight linear that performs well above its modest price. With a 50g actuation, an INK-blend top housing and a full POM stem and bottom, it delivers the kind of deep, rounded sound and clean glide that usually costs a lot more per switch. If you want a value linear that needs minimal work to feel premium, this is an easy recommendation.

Specs and Feel

This is a textbook linear: a uniform 50g push from top to bottom with no bump or click to interrupt the keystroke. Pre-travel sits at 2mm with a 4mm total stroke, so it follows the standard MX layout and drops into any compatible board. The stroke is genuinely smooth. The POM-on-INK material pairing keeps friction low, and stock scratch is minimal rather than absent. Stem wobble is well controlled for the price, tight enough that larger keycaps don’t feel sloppy. The 15mm steel spring gives a consistent, slightly springy return without the harsh ping cheaper switches sometimes carry. Sound leans deep and full thanks to the POM bottom housing, reading muted rather than clacky.

Tuning

Out of the box these are already enjoyable, but they reward a little effort. A thin coat of 205g0 on the rails and a touch of oil on the springs erases the last of the stock scratch and tightens up the bottom-out. Films are largely unnecessary given the already-decent housing fit. Most builders can skip them and put that time into lubing instead.

Verdict

Buy these if you want a smooth, deep-sounding linear without spending serious money. The CJ Dark Blue gives you genuinely good stock feel and clear gains from basic lubing, which makes it a strong pick for a first hand-lubed build or a budget-conscious full board. Anyone chasing a lighter, faster switch should look elsewhere, but as a medium-weight everyday linear it’s hard to beat at this price.
