Overview
EN 4198:2006 - Aerospace series - Rod-ends, adjustable self-aligning plain bearing with self-lubricating liner and threaded shank in corrosion resisting steel - Dimensions and loads - defines the dimensional, material and load characteristics for adjustable rod-ends used in aerospace flying control rods and structural rod applications. The standard applies to rod-ends that combine a self-aligning ball bearing with a self-lubricating liner (per EN 2501) and a threaded shank in corrosion resisting steel, and covers design features such as identification grooves and optional locking grooves. Use temperature range is −55 °C to 163 °C.
Key topics and requirements
- Scope and configuration
- Specifies rod-end assemblies: self-aligning plain bearing (EN 2501) + threaded rod-end body.
- Identifying features: circumferential groove (identification) and optional longitudinal groove (for locking).
- Groove(s) are to be painted red for identification.
- Dimensions and tolerances
- Detailed dimensional tables and tolerances (Figure 1, Tables 1 & 2) define diameters, thread lengths, and form limits.
- Surface roughness values given before surface treatment.
- Materials and hardness
- Rod-end bodies in corrosion resisting steel per referenced aerospace steels (e.g., EN 2539 / EN 3161 family).
- Specified hardness range for rod-end body (example: HRC 35–42).
- Plain bearing liner per EN 2501 (self-lubricating).
- Loads and performance
- Permissible dynamic radial loads, axial push-out loads, starting torques and ultimate static loads are specified (numeric values provided in the standard’s load table).
- Users must apply appropriate safety factors for permissible static loads.
- Surface treatment & marking
- Surface treatment options referenced to ISO 8075; marking per EN 2424 (category A).
- Designation
- Standard includes a clear designation/part-numbering scheme (example: EN4198L06KT) and codes for thread direction and groove options.
Applications and who uses it
- Typical applications: flying control rods, actuator links, aerospace structural rods and mechanisms requiring self-aligning articulation.
- Primary users:
- Aerospace design and mechanical engineers (component selection, interface design).
- Procurement and specification writers (calling out EN 4198 rod-ends in procurement documents).
- QA/inspection and maintenance teams (verification of dimensions, loads, markings and corrosion-resistant treatments).
- Manufacturers of rod-ends and bearing assemblies (product design and certification).
Related standards
