FDN and FDR Series: Heavy-Duty Steel Rollers for Reliable Pallet and Package Transportation

The FDN and FDR series are comprised of all-steel rollers dedicated to the transportation of pallets and packages with temporary accumulation. The FDN version provides sufficient drive to handle any deformation of the load transported. It can move materials on roller conveyors with a slight incline or that require lateral containment systems (with which the material generally comes into contact, generating localised friction). The FDR version, which has similar characteristics to the above, also has an adjustable axial friction pre-loading system. This provides supplemental force for particularly critical situations with irregular movement and/or elevated resistance.

Standard use is for ambient temperatures of between -20°C and +60°C, at a maximum peripheral speed of 0.5 m/s. For the selection and dimension of these components, prior consultation with Rulmeca is recommended.
