What the thread found

• ARRI specifies Finish Line Wet Bike Lubricant for gimbal bearings; the proprietary ARRI oil was previously available through ARRI branches and rental houses for approximately 10 USD per bottle.
• One operator's maintenance procedure: disassemble the gimbal, soak bearings in acetone, then apply exactly one drop of oil; this operator later upgraded to a GPI PRO gimbal bearing and reported superior performance.
• Tri-Flow is used by a established gimbal manufacturer, is inexpensive, and is readily available in retail supply chains.
• Alternative lubricants include watch movement oil for gimbal bearings and ceramic bicycle grease for arm pivots; bearing selection depends primarily on operating speed and load rating.
• Maintenance frequency is at least as critical as lubricant choice; operators should consult gimbal-specific service documentation before disassembly and cleaning.

Depends on

• Gimbal model and bearing type (standard versus ceramic or sealed designs)
• Operating conditions (speed and load)
• Availability of proprietary ARRI oil by region and rental-house stock
• Conflicting recommendations between specialty oils and general-purpose bicycle lubricants without field consensus
