The SI T/K female rod end bearing is a precision-manufactured, maintenance-free rod end bearing with internal threads (left-hand or right-hand available), specifically designed for internal linkage connections in equipment. It adopts a steel/polytetrafluoroethylene (PTFE) composite sliding pair. The ball is made of heat-treated bearing steel (hardness HRC 58-62) with hard chrome plating, the outer ring is brass, and the rod end body is made of medium carbon steel with environmentally friendly zinc plating. The integrated self-lubricating structure eliminates the need for regular grease injection. The four-piece core design significantly enhances impact resistance, enabling stable bearing of tensile and compressive loads on internal equipment linkages. It effectively simplifies equipment maintenance processes during long-term operation and is compatible with a wide range of metric sizes, meeting the precise assembly requirements of internal linkages in various equipment.

Gonuo SI T/K female rod end bearing is a precision-engineered metric rod end bearing designed for industrial equipment requiring smooth angular movement, high wear resistance and long-term maintenance-free operation.

Gonuo is a rod end bearing manufacturer in China specializing in self-lubricating and maintenance-required rod end bearings, ball joints and mechanical linkage components. The SI T/K Series is manufactured for global OEMs, distributors, machinery manufacturers and industrial equipment suppliers.

We support OEM/ODM production, custom thread configurations, material options and non-standard rod end bearing requirements based on customer drawings and application specifications.

Core Advantages

1. Maintenance-free self-lubricating design

The steel/PTFE sliding pair provides low-friction movement without regular grease lubrication, reducing routine maintenance requirements and making the SI..TK rod end bearing suitable for difficult-to-access mechanical linkages.

2. Metric Female Internal Thread

The SI T/K rod end bearing features a female internal thread for direct connection with threaded components. Metric thread options are available across a broad range of bore sizes to support different mechanical assembly requirements.

3. PTFE Sliding Surface

The steel/PTFE composite sliding pair is designed to reduce friction and wear during angular movement. This makes the SI T/K Series a suitable PTFE rod end bearing for industrial machinery and linkage systems.

4. RH and LH Thread Options

Standard SI T/K models are available with right-hand internal threads. For left-hand thread requirements, the letter “L” is added to the bearing designation, such as SIL18T/K.

5. Wide Range of Metric Sizes

The SI T/K Series covers metric bore sizes from 5 mm to 50 mm, including SI5T/K, SI6T/K, SI8T/K, SI10T/K, SI12T/K, SI16T/K, SI20T/K, SI25T/K, SI30T/K, SI35T/K, SI40T/K and SI50T/K.

Sliding Contact Pair:	Steel/PTFE Composite
Rod End Body Material:	Medium Carbon Steel, Environmental Zinc Plated
Outer Ring Material:	Brass
Ball:	Bearing Steel, Heat Treatment, Hardness HRC 58-62, Hard Chromium Plated

The SI T/K Series includes multiple metric female rod end bearing sizes to accommodate different linkage and load requirements. Standard models include SI5T/K, SI6T/K, SI8T/K, SI10T/K, SI12T/K, SI14T/K, SI16T/K, SI18T/K, SI20T/K, SI22T/K, SI25T/K, SI28T/K, SI30T/K, SI35T/K, SI40T/K and SI50T/K.

Depending on the required thread specification, selected sizes are also available with alternative thread pitches, including SI10-1T/K, SI12-1T/K, SI14-1T/K, SI16-1T/K and SI30-1T/K.

Tips:
If the thread is left-hand (LH), the letter "L" must be appended to the bearing designation, e.g., SIL 18 T/K.
For bearings made of stainless steel, add the prefix “S” to the model designation, e.g., SSI8 T/K.

Industrial Automation: SI T/K self-lubricating female rod end bearings are used in automated production lines, packaging machinery, printing equipment and textile machinery for linkage and positioning mechanisms requiring reliable angular movement.

Construction Machinery: The SI T/K Series can be used in control linkages and mechanical joints for excavators, loaders, compactors and other construction machinery exposed to demanding operating conditions.

Material Handling: These PTFE rod end bearings can be applied to conveyors, lifting platforms and automated material-handling equipment requiring durable pivot connections.

Off-Highway Vehicles: SI T/K rod end bearings are suitable for steering, throttle and control linkages used in tractors, agricultural machinery and off-highway vehicles.

Hydraulic & Pneumatic Cylinders: The metric female rod end bearing provides a compact connection solution for hydraulic cylinders, pneumatic actuators and motion-control systems where smooth angular movement and reduced maintenance are required.
