MachLine ® : a vast array of solutions HNS bearings: N This bearing is a direct result of SNR's aeronautical know-how and its performance data for machine tools are remarkable: - Increased rotation speeds, - Better fatigue resistance, - More reliable even when poorly lubricated, - Longer life, - Corrosion resistant. Characteristics: Bearings made of stainless martensitic steel with nitrogen (material used in aeronautics). - Rings made of XD15N. - Ceramic balls. Precision self-locking nuts Available in narrow or wide gauge, with a choice of 2 or 4 locking inserts, using blind holes or slots, the SNR range of precision self-locking nuts covers all requirements on the market. These products are vital: - for all precision bearing assemblies, - when a set of bearings need a guaranteed preload, which can be maintained over time, - for high axial loads. 10
• Preloading, definition of symbols 12-14 • Rigidity, axial deflection 15 General technical details Each application has its own specific speed and load requirements, with a significant impact on geometry, material or lubrication. Over the next few pages, our engineers give you all the information necessary to make the optimum choice of bearings and how to install them correctly. • Influence of an external axial load 16 • Speed correction factor 17 • Spindle design 18-24 • Lubrication 25-27 • Selection guide 28-29 • Ceramic ball bearings (CH) 30-31 • High speed bearings (ML) 32 • Sealed bearings (MLE) 33 • HNS bearings (N) 34 • Assembly demonstration 35-36
