BS EN 3048 is a European Standard series that covers spherical plain bearings for aerospace applications to ensure compatibility with systems, corrosion resistance and vibration resistance in aerospace applications.
BS EN 3048 specifies the characteristics of spherical plain bearings in corrosion resisting steel, with self-lubricating liner, light series, for elevated load at ambient temperature, with or without swaging groove, intended for use in the fixed or moving parts of the aircraft structure and control mechanisms.
Spherical plain bearings in BS EN 3048 shall be used in the temperature range – 55 °C to + 163 °C.
BS EN 3048 on spherical plain bearings for aerospace applications is useful for:
The spherical plain bearing allows angular rotation in two orthogonal directions around a centre point. They consist of an inner ring with a convex sphere exterior surface and an outer ring with a concave sphere inside the surface. In aerospace applications, they are used in components such as wing flaps, engine mounts, hatches and joints.
BS EN 3048 provides you guidance on configuration, dimensions, tolerances, mass, surface roughness, loads and starting torques, enabling you to standardize the dimensional and physical properties of spherical plain bearings for aerospace applications.
BS EN 3048 also provides you guidance on materials for spherical plain bearings for the inner ring, outer ring and liners to ensure improved strength and corrosion resistance in aerospace applications.
By adopting BS EN 3048, you can develop and assess spherical plain bearings to ensure stability, improved load-bearing capacity and durability in aerospace operations.
