The SA...T/K Series Rod End Bearing (often referred to as a Heim joint) is an articulating mechanical joint designed to connect steering links, tie rods, and hydraulic cylinders. The "SA" prefix denotes a male (external) thread, while "T/K" indicates a maintenance-free, self-lubricating design. The outer ring is inlaid with a PTFE-composite friction material that interfaces with the steel inner ring, allowing it to operate smoothly without the need for additional grease. This makes it perfectly suited for environments where regular lubrication is difficult or impossible.
Ensure compatibility with your mechanical linkages using the precise dimensions below.

(Note: We supply the entire SA...T/K series, including SA6T/K, SA8T/K, SA10T/K, SA14T/K, SA16T/K, SA18T/K, SA20T/K, SA22T/K, up to SA50T/K.)
As a representative of high-quality industrial manufacturing, our SA12T/K bearings deliver specific advantages for OEMs and maintenance crews:
Self-Lubrication: The PTFE-fabric liner provides a continuous, dry sliding surface, dramatically reducing maintenance costs and downtime.
Misalignment Tolerance: Readily absorbs angular misalignments between the support shaft and the housing hole without binding or losing power transfer efficiency.
Dual Load Capacity: Designed to accommodate both heavy radial loads and moderate axial loads simultaneously.
Rod end bearings are highly versatile and critical to power transmission and linkage systems across multiple sectors:
Automotive & Racing: Suspension systems, steering tie rods, and transmission linkages.
Industrial Machinery: Packaging equipment, machine tools, and heavy-duty industrial presses.
Agriculture & Construction: Tractor linkages, water pump actuators, and crane mechanics.
Backed by a global marketing network, we provide efficient service commitments to industrial parts distributors worldwide.
Availability: Normally ready goods and stock are dispatched within 3–15 days.
Payment Terms: Flexible options to support your cash flow, including 100% T/T, 30% T/T in advance with 70% against copy of B/L, 30% T/T with 70% against L/C, and Western Union.
Q1: What is the difference between SA12T/K and SI12T/K?
A: The "SA" series features a Male (external) threaded shank, while the "SI" series features a Female (internal) threaded body. Both use the same T/K self-lubricating inner bearing mechanism.
Q2: Can I get this bearing with a left-hand thread?
A: Yes. For left-hand male threads, the standard designation is SAL12T/K. If you are building turnbuckles or adjustable linkages, you will typically need one right-hand (SA) and one left-hand (SAL) bearing per rod. Please specify your thread direction when ordering.
Q3: Do these bearings require greasing before installation?
A: No. The T/K designation means they are lined with a PTFE (Teflon) composite material. They are entirely maintenance-free and should not be lubricated, as adding grease can actually attract dirt and wear out the PTFE liner prematurely.
