Gimbal bearing lubrication: oil quantity, product selection, and the performance versus protection trade-off.

DisputedParticipants disagreed and reached no conclusion. Read the findings as positions, not as an answer.

The manufacturer website recommends a maximum of 4 drops, while the manual suggests 5 to 10 drops, creating initial ambiguity.
One approach applies 3 to 4 drops at 12, 3, 6, and 9 o'clock positions, working them into the inner and outer races; excess oil increases resistance.
Broad consensus favors starting with a single drop, prioritizing smooth performance and adding more only if needed.
More oil protects the bearing better, requires less frequent cleaning, and resists dust ingress more effectively, but increases friction—especially with higher-viscosity oils.
Practical technique: apply one drop, rotate the bearing slowly by ear; if it grinds or squeaks, add oil; if it runs smooth and silent throughout rotation, the sweet spot is reached; if it stops abruptly, too much has been applied.
Mobil Velocite No. 6 is recommended at one drop for standard use or two drops for enhanced bearing protection; it is also available as sewing machine oil.
Several operators received Tiffen Steadicam® M1 and M2 gimbals factory-filled with excess oil or grease; installing a better bearing and using only a tiny drop eliminated pan wobble and sluggishness.
A Swiss watch lubricant laboratory recommended synthetic grease 9415 (operating range −30 to +80 °C) when contacted.
ACF-50 (aviation corrosion preventative fluid) has proven effective on cranes and jibs; its use on Steadicam® gimbals remains untested.
