The SA..T/K Series is a maintenance-free rod end bearing with external threads, specifically engineered for external linkage connections in equipment. It is equipped with left-hand or right-hand external threads and adopts a steel/PTFE composite sliding pair. Core components are identical to those of the SI..T/K Series—heat-treated bearing steel ball (HRC 58-62 with hard chrome plating), brass outer ring, and medium carbon steel rod end body with environmentally friendly zinc plating. The overall structure is optimized for high tensile/compressive loads and complex environments of external equipment linkages. The maintenance-free PTFE bushing is suitable for long-term operation in outdoor/open environments. The external threads allow direct and secure fastening with internal threaded holes/nuts, ensuring easy assembly. With full coverage of metric sizes, it is a highly reliable fastening solution for external linkages in construction machinery, off-highway vehicles, and other equipment.

Core Advantages

1. Self Lubricating Design for Maintenance-Free Operation

The key advantage of the SA-T/K series Rod End Bearing is its self-lubricating structure. The integrated PTFE sliding layer provides excellent wear resistance and reduces friction during repeated movement.

This Self Lubricating Male Rod End Bearing does not require frequent grease lubrication, helping customers reduce maintenance costs and improve equipment reliability.

Main benefits:

Maintenance-free operation

Reduced friction and wear

Longer service intervals

Stable performance under continuous movement

2. Metric Male Thread Structure for Easy Installation

The SA-T/K series adopts a male thread connection design, allowing direct installation into components with matching internal threads.

The Metric Male Thread Rod End Bearing provides:

Accurate positioning

Secure mechanical connection

Simple assembly process

Reliable load transmission

This structure makes the bearing suitable for mechanical linkage systems requiring compact installation and precise motion control.

3. High Strength Steel Construction

Manufactured from high-quality steel materials, the SA-T/K series provides excellent mechanical strength and durability.

The Steel Rod End Bearing design ensures stable performance under dynamic loads, vibration, and repeated angular movement.

Material advantages include:

High-strength steel body

Precision-machined inner ball

Excellent impact resistance

Long operating lifespan

4. PTFE Sliding Layer for Low Friction Performance

The SA-T/K series uses a PTFE composite sliding material to achieve smooth movement without additional lubrication.

As a reliable PTFE Rod End Bearing, it provides:

Low friction coefficient

Excellent wear resistance

Reduced maintenance requirements

Stable performance in demanding environments

The PTFE layer helps maintain smooth operation even in applications where regular lubrication is difficult.

Different thread sizes and dimensional options are available to meet various industrial requirements.

Tips:
If the thread is left-hand (LH), the letter "L" must be appended to the bearing designation, e.g., SAL 18 T/K.
For bearings made of stainless steel, add the prefix "S" to the model designation, e.g., SSA8 T/K.
