General Information
Relations
Overview
SIST EN 4036:2021 is a European standard developed by CEN that specifies the dimensions, loads, and key characteristics of aerospace adjustable rod ends featuring self-aligning double row ball bearings with reduced internal radial clearance. These rod ends are constructed from corrosion resisting steel and include a threaded shank, designed specifically for slow rotations and oscillating loads. The standard ensures uniformity and reliability for critical applications such as flight control rods and various aerospace structural components, supporting safe and durable aerospace operations.
The standard accommodates operating temperatures from -54 °C to 150 °C, with specific lubrication recommendations that affect applicable temperature ranges. It replaces the earlier EN 4036:2006 and aligns with recognized aerospace quality management systems to guarantee manufacturing and performance consistency.
Key Topics
Design Characteristics
- Adjustable rod ends incorporating:
- Circumferential groove for precise location identification
- Selection of seals or shields for protection
- Optional longitudinal groove for locking mechanisms
- Inner ring containing balls for self-aligning double row ball bearings
- Adjustable rod ends incorporating:
Materials and Surface Treatment
- Rod ends produced from corrosion-resistant steel conforming to EN 3490 or TR 3775 standards, with case hardening and tempering for enhanced strength and durability
- Bearings made from hardened steel per EN 2030 or EN 2226 with surface passivation treatments (ISO 8074 for rod ends and ISO 8075 for bearings)
- Seals constructed from PTFE or reinforced PTFE; shields made from corrosion-resistant materials
Load and Torque Specifications
- Defined permissible static radial and axial loads optimized for slow rotation and oscillation applications
- Maximum starting torque values specified for both sealed and shielded configurations
- Radial and axial clearances minimized to enhance precision and performance under load conditions
Thread Specifications
- MJ rolled threads per ISO 5855-2 for both right-hand and left-hand threads
- Precision requirements include burr removal and sharp edge breaking to secure reliable mechanical connections
Lubrication and Temperature Range
- Two types of greases recommended:
- Very high pressure ester-type grease (Code A) effective between -73 °C to 121 °C
- Very high pressure synthetic hydrocarbon grease (Code B) effective between -54 °C to 177 °C (per EN 2067)
- Usage temperature limits depend on selected lubrication code, influencing operational reliability
- Two types of greases recommended:
Quality Management and Marking
- Compliance with aerospace quality standards such as EN 9100 and EN 9133 to ensure product traceability and manufacturing excellence
- Markings follow EN 2424 style A for identification and traceability
Applications
SIST EN 4036:2021 rod ends are primarily applied in aerospace environments, including:
- Flight control rod linkages demanding precise, reliable articulation under oscillatory loads
- Structural aerospace components requiring corrosion-resistant, high-strength adjustable joints
- Aerospace mechanisms operating in extreme temperature ranges where lubrication compatibility is critical
- Slow rotational and oscillating pivot points in aerospace vehicles where minimized internal clearances prevent looseness and ensure high performance
These rod ends contribute critically to the safety, functionality, and longevity of flight-critical systems and other aerospace mechanical assemblies.
Related Standards
Compliance with SIST EN 4036:2021 is complemented by adherence to the following key standards:
- EN 2067 - Technical specification for rod ends with self-aligning ball bearings and grease types
- EN 9100 - Quality management system requirements for aviation, space, and defence organizations
- EN 9133 - Qualification procedures for aerospace standard products quality assurance
- EN 2424 - Marking of aerospace products, ensuring traceability
- ISO 5855-2 - Limits and tolerances for aerospace MJ rolled threads on bolts and nuts
- ISO 1132-1 - Terminology and tolerances for rolling bearings
These interrelated standards ensure the rod ends meet aerospace industry demands for safety, precision, and durability.
