The SA...ES and SI...ES series are high-performance spherical plain bearings designed for applications requiring articulation and load support. The key difference between the two series is their thread configuration:
SA...ES Series: Male Thread (External Thread). The bearing has a threaded stud that screws into a tapped hole.
SI...ES Series: Female Thread (Internal Thread). The bearing has a threaded hole that accepts a bolt or screw.
The suffix "ES" typically indicates that the bearing is equipped with seals (e.g., rubber or PTFE seals) to protect against contaminants and retain lubrication .
High Load Capacity: Capable of withstanding high radial loads and moderate axial (thrust) loads simultaneously. They are designed for heavy-duty applications .
Self-Aligning & Angular Misalignment: The spherical design allows for significant angular misalignment (typically ±6° to ±15°), accommodating shaft deflection and misalignment without binding .
Sealed Design (ES): The "ES" variant includes integrated seals that protect the sliding surfaces from dirt, dust, and moisture, extending service life and reducing maintenance frequency .
Re-lubrication Capability: Most models feature lubrication grooves and holes, allowing for periodic re-lubrication to flush out contaminants and maintain performance .
Durable Construction: Manufactured from high-carbon chromium steel (Gcr15) or stainless steel, offering excellent wear resistance and durability in harsh environments .

These bearings are critical components in systems that require a pivoting or oscillating motion:
Construction Machinery: Linkages in excavators, bulldozers, and cranes.
Agricultural Equipment: Steering linkages, hydraulic cylinder ends in tractors and harvesters.
Industrial Automation: Robotic arms, conveyor systems, and automated machinery joints.
Hydraulic Systems: Rod ends for hydraulic cylinders and actuators.
Transportation: Suspension systems, steering linkages, and control rods
Q1: What is the difference between SA...ES and SI...ES?
A: SA...ES has an external (male) thread and is screwed into a component. SI...ES has an internal (female) thread and is mounted onto a bolt or stud. The choice depends on the assembly design of your machinery .
Q2: What does the "ES" suffix mean?
A: "ES" stands for Sealed. It indicates that the bearing is equipped with contact seals (usually made of rubber or synthetic material) on one or both sides to prevent the ingress of contaminants .
Q3: Are these bearings self-lubricating?
A: Standard SA/SI...ES bearings are typically lubricated and require periodic greasing. However, self-lubricating variants (often denoted with suffixes like "TK" or "2RS") are available, which have a PTFE or composite lining for maintenance-free operation in certain conditions .
Q4: What is the typical operating temperature range?
A: For standard steel versions, the operating temperature range is typically between -50°C to +200°C (-58°F to +392°F). Special materials or coatings may be required for extreme temperatures .
Q5: How do I select the right size?
A: Selection is based on the thread size (e.g., M10, M20) and the bore diameter (d). Refer to the manufacturer's dimensional tables for specific load ratings and dimensions corresponding to the model number (e.g., SA20ES, SI15ES)
