What is BS EN 4854‑3 - Spherical plain bearings - Technical specification about ?
BS EN 4854‑3 is part one of a multi-series of European standards on aerospace series that covers technical specifications for spherical plain bearings in corrosion resisting steel.
BS EN 4854‑3 specifies the required characteristics, inspection and test methods, qualification and acceptance conditions for spherical plain bearings in corrosion resisting steel with self-lubricating liner, low starting torque and low friction coefficient, elevated duty cycles under low oscillations at different operating conditions.
Who is BS EN 4854‑3 - Spherical plain bearings - Technical specification for ?
BS EN 4854‑3 on spherical plain bearings technical specification is useful for:
- Aerospace parts manufacturers
- Spherical plain bearings manufacturers
Why should you use BS EN 4854‑3 - Spherical plain bearings - Technical specification ?
Spherical Plain Bearings (also known as “Spherical Plane Bearings” "Spherical Ball Bushing Bearings" and “Ball Bushings”) have an inner ring with a sphere convex outside surface and an outer ring with a corresponding sphere, but concave inside surface. Their design makes them particularly suitable for bearing arrangements where alignment movements between shaft and housing must accommodate, or where oscillating or recurrent tilting movements must be permitted at relatively slow sliding speeds.
These self-lubricating spherical plain bearings are intended for use in fixed or moving parts of the aircraft structure, especially for control mechanisms and operating systems. The bearings are designed subjected under low dynamic radial loads and slow rotations in the temperature range of −55 °C to 120 °C (−67 °F to 248 °F).
The liner may be of a fabric or composite material bonded to the inside diameter of the outer ring or in a composite material moulded into a pre-formed cavity between the inner and outer rings.
Control mechanisms and operating systems are crucial for aerospace series and BS EN 4854‑3 can help you achieve efficiency and build credibility for the same.
With the use of BS EN 4854‑3, you get to know the required characteristics, inspection and test methods, qualification and acceptance conditions of spherical plain bearings in corrosion resisting steel with a self-lubricating liner which can be very helpful for use in aerospace applications.
