Identifying and servicing a modified Cinema Products 3A arm with aftermarket Silver Springs, and adjusting spring tension for different camera weights.
What the thread found
- The arm was identified as an original Cinema Products 3A chassis upgraded by Steadyrig (Australia) with Silver Springs, bronze bushings, fine-threaded stainless steel screws, and Steadyrig spring covers.
- Steadyrig previously offered upgrades to existing 3A chassis; a maintenance manual is available from the manufacturer, and the arm is noted as easy to clean.
- The Steadyrig arm has a load capacity of approximately 13–63 lb (6–29 kg).
- A key advantage of this design is that the springs can be completely unscrewed and replaced individually per section, allowing the arm to be tuned to the specific camera weight in use.
- One operator mentioned Titan grease for joint lubrication, though this was not confirmed by other participants.
Depends on
- Load capacity and spring tuning depend on the specific section configuration and camera weight range.
- Joint lubrication specifications were not definitively established in the discussion.
