Guide rollers hold camera steady on gantry suspended over race track

Posted by Simon Barrell on Jun 15, 2010 3:22:00 PM

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.

Self-Lubricating cam followers replace steel in outdoor applications

Posted by Simon Barrell on Nov 16, 2009 11:09:00 AM

Our customers have been asking us to help them with components for machines that will operate in ever harsher conditions. Intech iCam Followers® and Power-Core™ guide rollers feature a unique crystalline structure that is resistant to flow under static load, and provides long-wearing, non-lubricated performance. The devices do not wear out the rail, do not absorb moisture and, when fitted with stainless steel bearings, are suitable for wash downs and harsh and corrosive environments.

Unlike other plastic material, Power-Core™ does not become brittle in low temperatures. iCam Followers® and Power-Core guide rollers reduce maintenance and down time by retaining good bearing fit from -40° to 160° F, retaining elasticity, and absorbing shock and vibration in sub-zero temperatures. The devices are not only quiet and easy rolling, they do not generate metal particles, which can further increase down time potential.

Intech Power-Core rollers, cam followers, and trolleys are assembled from precision machined high performance, self lubricating engineered plastic tires and quality roller bearings. The plastic part of the roller fully envelopes and embraces the bearing outer racer which in turn provides high capacity to carry side loads.

The Power-Core rollers and iCam Followers® are available in stock sizes with load capacity from 60 to 500 lbs. Trolley assemblies feature aluminum track and trolley systems with attachments. Custom sizes and dimensions and tire shapes can be developed to meet specific applications.

Guide Rollers Provide Secure Fit Under Varying Loads & Temperature

Posted by Alexander Bartosch on Aug 13, 2009 3:24:00 PM

Intech was selected by Bombardier to provide replacement rollers for the platform safety door on the Orlando People Mover System.

Bombardier Transportation, with a reputation for excellence in designing high capacity urban transit systems and automated people movers, required longer wear-life rollers, with increased reliability to reduced maintenance. Our design engineers at Intech Corporation, explored how the engineered Intech powercore rollers might address Bombardier Transportation’s requirements.

 

Concave Rollers For Sliding Door Hardware

Concave Rollers for Guide Door Openings Once application details, including angle, load, door weight, linear speed, temperature variations, humidity levels, rail material and cycling information were presented, Intech was able to custom design a concave roller. The assembly features a precision machined Intech Power-Core™ tire thermally installed over a sealed ball bearing. At a radial load of 100 lbs. per roller running at 53.82 ft/min, Intech determined roller performance life of between 500 to 700 million door-opening cycles, which could potentially provide the Orlando International Airport with 5 to 7 years of quiet, trouble-free and maintenance-free operation.

Intech Power-Core™ rollers do not absorb moisture and maintain outstanding performance characteristics throughout a temperature range that extends from -40°F to 140°F. The precision thermal-fit tire is credited with providing a reliable and secure fit under varying load and temperature situations.

After one year of continuous operation, there are no visible signs of wear on the roller surface. Additionally, Intech Power-Core™ rollers are being installed on the heavy 200 lb. glass station doors in order to reduce noise and increase resistance to grinding and wear. Station door rollers for Leg A2 are in the process of being replaced at the Orlando site with Intech Power-Core™ replacement rollers. Bombardier field technicians are installing the replacement rollers and, where applicable, will ensure that they are timed to open and close at precision-controlled intervals so that the doors orchestrate perfectly with the opening of train doors to provide a safe, smooth passage.
