MEII has expanded the use of rollers to high speed applications. Our new roller is designed especially for high speed tape applications. With this new roller you get the advantages of rollers even at very high speeds and at low wrap angles.

A tape roller bearing is provided that prevents the development of an air film between the roller surface and the tape. The spool surface is made from porous material so that air flows through the spool surface. The porous material vents air uniformly over the roller surface, and the tape remains in direct contact with the roller, even at high speed. The inventive roller has many advantages, including improvement of tape wear characteristics, enhancement of tape guiding abilities, and increased tape speed stability.
