Bag Lubing vs Stem Lubing Linear Switches: Best for Beginners

What “Lubing” Actually Fixes

Linear switches like Gateron Yellows, Akko Cream Yellows, or Tecsee switches almost always ship scratchy. Factory tolerances are loose, lubrication (if any) is inconsistent, and the result is a stem that wobbles or catches on its way down. Lubing fixes that by cutting friction between stem and housing, which:

The real question for a beginner isn’t whether to lube. It’s how to do it without burning an entire Saturday on 90 switches and still ending up with half of them feeling different from the rest.

Bag Lubing: The Beginner-Friendly Shortcut

Bag lubing is exactly what it sounds like: you drop your disassembled stems (sometimes springs too) into a zip-lock bag, add a small dab of lube, seal it, and shake or knead the bag until everything’s coated.

Pros:

Cons:

Best for: your first 50-120 switch batch, anyone who values speed over micro-tuning, and budget switches with rough factory tolerances (stock Outemu, Gateron Pro, that sort of thing).

Stem Lubing: The Precision Route

Stem lubing means picking up each stem individually and brushing lube (a size 0 or 2 brush works well) onto the four rails and two legs where the stem meets the housing.

Pros:

Cons:

Best for: intermediate builders, high-end switches like Boba U4 or JWK Alpaca, and anyone who’s already bag-lubed a board before and has a baseline to compare against.

Which One Gives Beginners More Consistency?

For a first project, bag lubing wins on consistency, and not because it’s more precise. It wins because it takes human error out of the picture. A beginner’s brush technique shifts from switch to switch; a bag’s shake-and-coat motion doesn’t care how steady your hand is. If the goal is “every switch in this board should feel the same,” bag lubing gets you there with way less risk.

Stem lubing has a higher ceiling once your hands know what they’re doing. But it starts with a lower floor: your first 20 switches will probably feel noticeably rougher or less even than your last 20, at least until your technique settles in.

A Practical Hybrid Approach

A lot of experienced builders don’t pick one method, they stack both:

  1. Bag-lube the stems first for an even base coat (a light lube like Krytox 205g0, or a 205g0/105g0 blend, works well here).
  2. After reassembly, test a few switches. If one still feels scratchy, spot-brush a little extra lube on just the rails.
  3. Handle housings and springs separately. Springs tangle and clump inside a bag, so bagging them rarely gives even results.

That combination hands beginners the consistency of bag lubing while still leaving a safety net for the odd stubborn switch.

Quick Decision Checklist

Conclusion

Neither method beats the other outright. They’re solving two different problems. Bag lubing is the beginner’s shortcut to fast, even, low-effort consistency across a big batch. Stem lubing rewards patience with finer control, once you actually know what feel you’re chasing. If this is your first time lubing anything, bag your stems, test a handful in your board, and only pick up the brush if something still feels off.
