Specializing in Maximizing Conveyor Uptime
Conveyor Pulley Specialist
RAS is a global leader in the design and manufacture of engineered class conveyor pulleys. Using our proprietary P-Flex software and over 40 years of experience, we design and manufacture pulleys for the world’s highest tension applications and most demanding climates. From Mongolia and Chile, to Indonesia, Canada and Sweden, RAS has supplied engineered class pulleys for clients all around the world.
Flexible Design Means Infinite Life
The key to our success is focusing 100% on flexible design principals and a complete understanding of dynamic pulley loads and how they relate to each component. Rigid design pulleys that are commonly manufactured in today’s marketplace often lead to high localized stresses and therefore downtime caused by broken shells and shaft fretting corrosion failures. The RAS infinite life design evolves within P-Flex, our in house engineering program developed for pulley design, estimating, manufacturing and ISO 9001 quality management.
P-Flex focuses on actual material properties and locking device bending moments, while checking both peak and running conditions in real time. We engineer flex into homogenous areas, where static and alternating stresses can easily be handled. The net result; a lighter, stronger, cost effective, fully engineered infinite life pulley that utilizes modern technologies to increase your uptime.
You can count on RAS for Engineered Conveyor Pulleys, Apron Feeder Head Shaft Assemblies, Take Ups, Bearing Assemblies, Couplings, Keyless Frictional Locking Devices and Standard Pulleys. As well as being your team member from the design phase right through to installation and after sales service.
Early 2014 we opened the doors of our new 5000 square meter manufacturing facility to keep up with industry demands for higher tension pulleys. We recently engineered and manufactured the first gearless drive pulley to be commissioned in over 20 years and have already designed ST 10 000 pulleys.
