Thin Section Bearings Ensure Rigidity of Camera Motion Control Rigs

Preston, WA (Silverthin eNews) Mar 2016

A UK-based designer and manufacturer of robotic motion control systems for live broadcast, film and photography applications, is utilising Silverthin® precision thin section bearings from Carter Manufacturing on a variety of its robotic motion control camera rigs. The thin section bearings are playing a key role in ensuring the overall system rigidity and repeatability of the camera booms and rigs.

One example of an MRMC camera rig that utlilises thin section bearings from Carter Manufacturing is the SFH50, a camera motion control pan tilt head. This system is a high precision, highly repeatable one that is ideal for virtual studios, virtual reality, animation, time lapse and web promotional videos. The system has an optional 360-degree roll axis and is compact and lightweight for film location work.

The SFH50 uses Silverthin® thin section bearings from Carter Manufacturing to support the circular motion of the camera roll housings. The bearings are supplied as sealed, preloaded (K-Preload) units in 6" and 7" bore diameters. "The SFH50 is a super-sensitive piece of equipment and so we require bearings that eliminate camera 'rock'. The Silverthin® thin section bearings are four-point contact units which are preloaded to a precise specification to give us the system rigidity and repeatability that our customers need."

"The bearings are sealed units, as the camera rigs are used in both indoor and outdoor applications, so we need weather-resistant components. In addition, as the bearings are preloaded, this simplifies and reduces mounting and assembly of the bearings to our camera rigs," states Ronan Carroll.
