SKF
Micro Units
SKF micro units are the smallest members of the MQL and oil+air families, designed for very compact installation spaces, typically within the confined work envelope of a CNC lathe or machining centre. They provide the same precision aerosol or oil+air mist generation as their larger counterparts but in a footprint measured in centimetres. A micro unit might serve one or two critical bearing or tool lubrication points where ultra-low flow and minimal space are paramount. They are popular in the Swiss-type lathe and small precision machining sectors. Despite their size, SKF micro units include reliable metering and monitoring functions, ensuring that the lubrication of the high-value spindle or guideway is never compromised.

The Micro Lubrication Unit in Swiss‑Type Lathe Spindles
The guide‑bush and main spindle bearings need precise oil+air lubrication in a space no larger than a cigarette packet. SKF’s micro unit fits in this tight envelope, providing the same delivery precision as a full‑size unit, enabling the Swiss lathe to run 24/7 at high speeds.
Battery‑Backed Micro Units for Portable Maintenance
A cordless, battery‑powered micro MQL unit can be carried to a remote conveyor bearing, connected with a magnetic nozzle, and left to deliver a timed lubricant dose. This is a flexible tool for maintenance teams trialling the effect of better lubrication on a suspect bearing before committing to a permanent installation.
