Most high-tech optical tracking systems require
components which enable engineers to combine weight and space savings with high positional accuracy. Silverthin bearings offer a combination of outstanding stiffness and excellent torque performance, housed in a compact and lightweight thin cross-section package. Key optical applications include Gyro-Stabilised
Gimbal Platforms which are used in cameras, sensors or other payloads to help maintain a steady orientation whilst eliminating unwanted vibrations or movements. They consist of three main components: gyroscopes, sensors and motors. The gyroscopes measure the angular velocity of the platform, detecting any changes in orientation. The sensors provide additional feedback on the platform’s position, whilst the motors adjust the orientation of the gimbal in real-time, counteracting any disturbances, keeping the camera or payload stable and level. This technology allows for smooth and steady footage or data collection, even in challenging environments such as moving vehicles or turbulent conditions. Today, these platforms are widely used in film production, aerial
photography, surveillance and remote sensing to capture high-quality, jitter-free images and data. Another application is Orbital Camera Rigs.
These are used in filmmaking and photography to capture dynamic, sweeping shots, with a circular or orbital motion. They typically consist of a camera mounted on a rotating arm or track systemthat allows smoothmovement around a central point or axis. By controlling the speed and direction of rotation, filmmakers can create stunning visual effects, such as circling around a subject or object, revealing a panoramic view or simulating the sensation of orbiting in space. The ultra-slim Silverthin designminimises the space required for the bearing assembly, allowing for the most compact and lightweight camera rigs. Laser Rangefinders, meanwhile, measure the
distance between the rangefinder and a target by emitting a laser beam and measuring the time it takes for the beam to reflect off the target and its return to the rangefinder. This measurement is based on the speed of light, allowing for highly accurate distance calculations essential to applications such as surveying, construction, hunting, golfing and military, where precise distance measurements are essential. Thin section bearings are used in laser
rangefinders due to their compact design, while low friction characteristics contribute to smooth operation, minimising any disturbances to laser beam alignment.
The bearings are also used in IR (Infrared) Imaging Systems. This technology captures and visualises infrared radiation emitted by objects or environments, detecting the heat emitted by objects and converting it into an image which is visible to the human eye, or to other sensors for analysis. IR systems are used in various applications including surveillance, security, medical imaging, firefighting and thermography where they detect temperature variations, identify objects in low-light or obscured conditions. Thin section bearings are, however, also
ideal for smooth action in articulating parts such as in the elbows of robotic arms and other similar articulating joints. They can also be used in work-holding devices such as turntables, indexing and rotary tables.
