What is BS EN 4035 about?
A rod end provides an effective point-to-point contact with the center of rotation lying on the axis of both attached shafts. Whereas self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring, and two deep uninterrupted raceway grooves in the inner ring. They have very high tensile strength and toughness (even at extreme temperatures), are light in weight, have extraordinary corrosion resistance, and have the ability to withstand extreme temperatures.
BS EN 4035 specifies the characteristics of adjustable rod ends with self-aligning double row ball bearing in corrosion resisting steel with reduced internal radial clearance and threaded shank in titanium alloy, designed to withstand only slow rotations and oscillations under load.
They consist of:
- A rod end comprising
- Circumferential groove to confirm that the assembled rod-end is “in safety” emphasized with the application of red paint
- Either seals or shields
- An optional longitudinal groove for locking purpose
- An inner ring with balls
These rod ends are intended for use with flight control rods or rods for aerospace structures and are intended to be used in the temperature range: −54 °C to 150 °C.
Who is BS EN 4035 for?
BS EN 4035 on characteristics of adjustable rod ends is applicable to:
- Aerospace parts manufacturers
- Adjustable rod end manufacturers
- Self-aligning double-row ball bearing manufacturers
- Structural engineers
Why should you use BS EN 4035?
BS EN 4035 provides aerospace manufacturers with best practice guidance regarding the dimensions and loads of adjustable rod ends with self-aligning double row ball bearing which can be used in fixed or moving parts of the aircraft structure and their control mechanisms.
Adopting this standard is vital to ensure the adjustable rod ends will withstand only slow rotations and oscillations under load, meaning that their performance can be trusted throughout the aerospace supply chain.
BS EN 4035 helps you identify the characteristics of these and ensure the maximum safety of the end-users of this product.
Adhering to the specifications under BS EN 4035 will help make rod ends ideal for mechanisms requiring precise and predictable control, thus making your product more reliable and safer to use in aerospace applications and construction
