The SI-C series female rod end bearing is a high-precision metric female rod end bearing featuring internal threads and double-sealed protection. Available with left-hand (LH) or right-hand (RH) threads, the SI-C rod end bearing is designed for internal linkage systems requiring high accuracy, reliable sealing and stable motion performance.

The SI..ET 2RS rod end bearing adopts a precision spherical plain structure with a heat-treated bearing steel ball (HRC 58-62) and hard chrome-plated surface for enhanced wear resistance and durability. The outer ring is made of brass, while the medium carbon steel rod end body is zinc-plated for improved corrosion protection.

Featuring a self lubricating rod end bearing design with PTFE bushing, the SI-C Series delivers smooth operation without frequent lubrication. The 2RS double seal structure effectively prevents grease leakage and contamination, making it an ideal maintenance free rod end bearing solution for automation equipment, precision machinery, automotive components and other high-precision linkage applications.

Core Advantages

1. Maintenance-Free Self-Lubricating Design

The maintenance free rod end bearing uses a PTFE composite liner structure to reduce friction and wear, providing smooth operation without regular grease lubrication.

2. High Wear Resistance & Long Service Life

The SI-C rod end bearing features optimized material selection and precision manufacturing, ensuring stable performance in continuous industrial applications.

3. Precision Metric Internal Thread

The SI-C metric rod end bearing follows metric dimensional standards and provides accurate internal thread connection for easy installation and reliable equipment integration.

4. Smooth Spherical Movement

The female spherical rod end bearing allows angular movement compensation while maintaining precise force transmission in mechanical linkage systems.

5. OEM Customization Capability

As a professional OEM rod end bearing manufacturer, Gonuo supports customized dimensions, thread specifications, materials and surface treatments according to customer requirements.

Tips:
If the thread is left-hand (LH), the letter "L" must be appended to the bearing designation, e.g., SIL6C.
For bearing bore diameter d ≥ 35, the ET 2RS (sealed) design is required.
