Rollers are used extensively in delicate material applications (such as carbon fiber winding) mainly due to their very low moment of inertia and low rolling resistance. Thanks to the ribbed construction, they are also suitable for applications with a large width of material, where they offer high resistance to deflection even under high loads.
We supply a wide range of guide rollers and aluminum profiles for all industrial applications. We offer profiles up to a length of 6 meters (anodized, straightened, deburred - butted on the faces), or we can deliver complete cylinders based on your requirements (storage, material tension, speed of rotation, etc.).
ALVEOTUBE 3RC profiles are made of one outer and one inner tube, connected by means of six radial ribs. Our 3RC profile provides the ideal ratio between deflection (according to load) and inertia.
The ball bearings are placed between the ALVEOTUBE profile and the supporting fixed shaft that passes through the entire body. The C3, Z and ZZ type ball bearings are lubricated with a special grease, which leads to a further reduction in torque and also to a reduction in noise (without affecting product life) compared to the standard type.
The cylinder pin is firmly connected to the aluminum body. Bearings for rotation are designed by the customer and are most often placed on the frame of the machine. According to your drawing, the pin can be machined into the final shape as needed. These cylinders are slightly cheaper and take less time to produce.
