Features of precision steel tubes used in the production of bearings:

• high dimensional precision (key feature);
• high surface quality – the inner and outer surface of the pipes should be very smooth and without damage, which affects the tribological properties of the bearings (referring to friction forces);
• high tensile and bending strength, which affects the durability and stability of the bearings;
• high resistance to fatigue and cyclic loads, which is especially important in the case of bearings operating in dynamic conditions;
• corrosion resistance to ensure long bearing life in harsh environmental conditions;
• high quality of steel, which affects the mechanical properties and durability of bearings;
• exact chemical parameters, such as carbon, chromium, manganese, phosphorus and sulfur content, which affect the properties of the steel.
