Roller bearing NR/NN series

cylindrical rollerspherical rollerball bearing

Wherever there’s a machine there is also a ball bearing reducing the friction, together with a pillow block supporting the shaft and a rod-end which helps reducing the misalignment. The distribution of bearings, pillow blocks and rod-ends is a Melucci strength since the 70’s, in addition to all components necessary for the motion transmission. Bearings Bearings Ball bearings Bore diameter from 1,5mm up to 1320mm, with a broad selection of ball bearings. Spherical roller bearings Spherical roller bearings are suitable for all application with strong radial solicitations. They bear strong bending of the shaft and help reduce the misalignment between the shaft and its slot. Taper roller bearings Their features offer various advantages in various sectors, such as agricultural, steel, aeolian and railways industry. Cylindrical roller bearings Designed to bear heavy radial loads, so they are suitable specially for industrial applications, such as robotics, aeolian or railways industry. There are two kinds of roller bearings: With cage, suitable for strong accelerations, high speed and heavy radial loads. Without cage (full complement cylindrical roller bearings) which incorporate a maximum number of rollers, and are therefore suitable for very heavy radial loads. The increased number of rollers also increases radial stiffness. Super precision bearings Super precision bearings offer the following advantages: Productivity: production cost optimisation Precision: High machining quality Reliability: Reduced maintenance costs Sustainable design: eco-friendly product
