What is BS EN 4036 about?
BS EN 4036 specifies the characteristics of adjustable rod ends with self-aligning double row ball bearing with reduced internal radial clearance and threaded shank in corrosion resisting steel, designed to withstand only slow rotations and oscillations under load.
They consist of:
- A rod end comprising
- Circumferential groove to identify location
- Either seals or shields
- An optional longitudinal groove for locking purpose
- An inner ring with balls
Who is BS EN 4036 for?
BS EN 4036 on 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 4036?
A rod end provides an effective point-to-point contact with the center of rotation lying on the axis of both attached shafts. This simplifies kinematic design and provides rigid mechanisms which do not subject control rods to bending moments. Rod ends consist of an eye-shaped head with an integral shank that forms a housing for a spherical plain bearing. 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. 
BS EN 4036 combines the two and provides us with information regarding 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. This information can be vital as these adjustable rod ends are designed to withstand only slow rotations and oscillations under load.
BS EN 4036 helps you identify the characteristics of these and ensure maximum safety of the end-users of this product. 
Adhering to the specifications under BS EN 4036, 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.
