Guide rollers hold camera steady on gantry suspended over race track

The average speed of a NASCAR car varies from one race track to another, it is calculated based on the winner’s lap speed through the entire race. The fastest track on the circuit is the Talladega Superspeedway, where the recorded average speed is about 188 miles per hour (303 kilometers per hour).

In order to capture video images of the race cars as they streak along the track at these phenomenal speeds, a camera needs to resist the buffeting and turbulence generated by the passing cars. Doggicam Systems adapted its patented movie camera system to create the Super Slide, a high speed light weight super-rigid rail system which allows the camera to be moved with precision and tremendous speed and acceleration.

A key component, that allows the Doggicam Systems Super Slide to deliver high speed precision and move safely within inches of the subject, are the Intech Power-Core™ rollers that we supply. These rollers ensure a smooth vibration free rolling transit of the camera system along the rail, with minimum resistance, allowing it to accelerate from 0-24’ / second in just one second and reach a top speed of 25’ per / second.

Intech Power-Core™ rollers eliminate both the need to lubricate and rail wear and offer an ideal long-lasting solution in the demanding conditions, from extreme heat, vibration, torrential rain, to freezing temperatures, to which the Doggicam Super Slide is exposed.

Intech guide rollers are also used in mechanisms that move cameras in TV studios or on film sets, where smooth, vibration free and quiet camera operation is paramount.
