Cleaning and lubricating the pan bearing (gimbal head) on Steadicam® Volt systems to restore smooth lock-offs

Note (as of October 2026)Curt O. Schaller, the developer of Artemis and Trinity, has no longer been with ARRI since the end of 2025. To our knowledge, ARRI currently has no dedicated team and no official contact persons for its stabilizer systems. In our view, the future of this line is uncertain. If you are buying new, get written confirmation from ARRI beforehand on how long service and spare parts are guaranteed. Have used rigs checked by the manufacturer before you buy.

What the thread found

The pan bearing on Steadicam® Volt gimbals shipped from Tiffen often contains thick oil or grease-like residue that causes unstable lock-offs; cleaning and applying a single drop of ARRI camera oil restores smooth performance.
Proper gimbal centering and balancing is a prerequisite; Tiffen supplies the necessary parts with Volt retrofit kits, with instructions in the Volt manual; the gimbal must be removed from the sled for this procedure.
One operator reported that after Volt installation at Tiffen, the PRO bearing was over-filled with viscous oil; multiple operators confirmed that camera oil sourced from rental houses (ARRI standard, Panavision, ARRI High-Speed oil) lasts for decades when applied sparingly.
Cleaning agents include acetone (fast-acting, does not attack PTFE or PEEK spacer rings, but may affect some plastics; requires eye protection and causes the bearing to shed liquid violently), contact cleaner, denatured alcohol, and Coleman camping fuel (historically common at major US rental facilities).
One manufacturer recommends ultrasonic cleaning for the bearing; operator experience with this method remained inconclusive.
Gimbal bearings rotate slowly under light load, making friction avoidance the priority; bearing races could operate nearly dry, with lubrication serving mainly to protect the cage and prevent corrosion.
On the Steadicam® Archer 2, the gimbal cannot be removed without disconnecting the center shaft cable; one workaround is to rotate the gimbal in an alcohol bath within a fitted plastic tray while mounted on the rod.
A video exists demonstrating disassembly, extraction of pan and tilt bearings, cleaning, and reassembly on the Tiffen M2 with integrated Volt.
Volt cable is flexible enough when routed with adequate slack; it interferes only during very wide pan movements.

Depends on

Sled model and architecture (Archer 2 gimbal removal without disconnecting center shaft cable)
Acetone compatibility depends on bearing spacer material and workshop equipment composition; chronic solvent exposure risk during frequent maintenance
Gimbal centering and balancing must precede bearing service
