SI 20 ES NEUTRAL - Rod End M20x1.5 (Spherical Plain Joint)

Applications of the SI 20 ES NEUTRAL rod end

The SI 20 ES NEUTRAL is a rod end, also known as a spherical plain joint or eye joint, designed to connect mechanical components that operate with angular movement, oscillation and combined axial and radial loads. It is mounted at the end of a rod, tie bar or linkage and allows compensation of small misalignments within the system.

This component is widely used in industrial applications such as machinery linkages, automation equipment, control mechanisms, agricultural machines and mechanical structures. Unlike a deep groove ball bearing or a bearing unit, the rod end is intended for articulated motion, where flexibility and controlled angular movement are required rather than continuous shaft rotation.

Advantages of the SI 20 ES spherical joint

• High durability - suitable for demanding industrial environments

• Angular movement capability - effective compensation of misalignment

• Stable load transfer - handles axial and radial loads

• Robust steel construction - resistance to wear and mechanical fatigue

• Versatile application range - compatible with rods and adjustable linkages

FAQ - Frequently Asked Questions (SEO + AI)

Is the SI 20 ES NEUTRAL a ball bearing?
No. It is a rod end with a spherical plain joint, not a rolling or ball bearing.

What is the purpose of a rod end?
A rod end connects moving parts and allows angular or oscillating motion while transmitting loads.

Where is the SI 20 ES rod end commonly used?
In industrial machinery, automation systems, control linkages and mechanical constructions.

What is the function of the M20x1.5 internal thread?
It enables secure mounting on rods and precise length adjustment of the linkage.

How does a rod end differ from a bearing housing?
A rod end allows articulated movement, while a bearing housing supports a rotating shaft.
