CYLINDRICAL ROLLER BEARINGS designed to go further

NTN-SNR the strength of a group As expert in managing the life cycle of a product, NTN in Europe is characterised by the proximity and commitment of its teams. We anticipate development projects on your strategic markets. Our engineers design with you solutions adapted to the most demanding applications, in fields such as railways, robotics or textile. NTN-SNR leads you towards reliability and performance. The product Designed to withstand high radial loads, our cylindrical roller bearings are available in 1, 2 or 4 rows, with crossed, high precision or complement rollers. 4 cage designs are...

THE CONTROL OF OUR SURFACE CONDITIONS The finishing process with lapping rod formerly known as «Superfinishing» enables surface condition values to be obtained (roughness Ra) of a dozen nanometres (in comparison, a standard turning process produces a roughness of 1 to 2 μm i.e. 1000 to 2000 nanometres). Such a performance lowers the André Mulatier Superfinishing Process Expert friction levels to a minimum and thus improves the torque. «We have a real expertise in superfinishing processes and we provide equipment for these with almost 400 dedicated machines. To better understand the interest of...

OUR EXPERIENCE IN RAILWAYS «For over 40 years, our cylindrical roller bearings have been equipping the axles of passenger and freight trains. The axle is a safety device on which a zero defect is mandatory. For this, we test our designs on the equivalent of 600,000 km in our COFRAC certified test centre. Once in production, we check all bearings (dimensions, material testing by ultrasound and magnetic-particle inspection) to ensure the complete reliability of our products.» Machine tools: MAZAK high-precision spindle bearings Textile: STÄUBLI shed forming system roller Steel: ThyssenKrupp Steel...
