Aerospace bearings require ultra‑clean, high‑strength steels such as M50, M50NiL, and 440C. Strict quality features include full material traceability, controlled heat treatment, non‑destructive testing, and compliance with aerospace standards to ensure reliability.
Aerospace bearings are subject to the highest material and quality requirements due to their use in safety‑critical systems such as aircraft engines, gearboxes, flight controls, and space mechanisms. Materials must provide exceptional rolling contact fatigue strength, dimensional stability over wide temperature ranges, high fracture toughness, and resistance to wear and corrosion. Cleanliness and microstructural homogeneity are essential to achieve long and predictable service life under cyclic and high‑speed loading.
High‑performance bearing steels such as M50 and M50NiL are widely used for their superior fatigue resistance, thermal stability, and controlled hardness profiles after precise heat treatment. Martensitic stainless steels like AISI 440C are selected where corrosion resistance is required. In specific high‑temperature or load‑intensive applications, nickel‑based alloys may be applied. Aerospace bearings are manufactured under stringent quality systems, ensuring full material traceability, validated heat treatment, and tight process control. Quality features include non‑destructive testing, fine surface finish, controlled internal cleanliness, and comprehensive documentation to meet aerospace certification standards and ensure maximum operational reliability.
BÖHLER N695 es un acero resistente a la corrosión con una adición de 17% de Cr y Mo en forma de barras, alambre, piezas forjadas y material de forja. Estos productos se han utilizado normalmente para piezas de ingeniería general y aplicaciones médicas cortantes y no cortantes, por ejemplo, cinceles, cuchillos, osteotomos, escalpelos, taladros, retractores, separadores, pinzas, bolas, rodillos, agujas y anillos para cojinetes resistentes a la corrosión que requieren una dureza de 58 a 60 HRC y resistencia al desgaste, la corrosión y la oxidación en función del diseño y la aplicación de las piezas, pero su uso no se limita a estas aplicaciones.
