SA12 Spherical Plain Bearing | SA12T / SA12K Steel And Stainless Steel
The SA12 spherical plain bearing is a standard female thread rod end bearing designed for light and medium-duty industrial automation and mechanical systems. It enables flexible multi-directional oscillation and tilting movement, featuring excellent self-aligning performance to compensate for installation deviation. Available in SA12T and SA12K models with bearing steel and stainless steel options, this bearing provides low-friction, high-stability motion solutions for general industrial and precision equipment.
SA12T vs SA12K | Model Differences
SA12T (Teflon Lined Type): Built-in PTFE liner delivers outstanding self-lubricating performance and ultra-low friction. It supports dry running operation without regular grease maintenance, making it ideal for clean, dry workshops and maintenance-free precision machinery applications.
SA12K (Open Lubrication Type): Standard open groove structure allows convenient grease refilling and efficient heat dissipation. With reliable wear resistance and stable load capacity after lubrication, it is suitable for long-cycle continuous operation and daily light-to-medium industrial working scenarios.
Material Introduction
Bearing Steel: Made of high-carbon chromium bearing steel with precise heat treatment. It owns high surface hardness, excellent wear resistance and structural rigidity, extending service life for conventional indoor industrial equipment.
Stainless Steel: Premium stainless steel features superior rust-proof, waterproof and anti-corrosion properties. It operates steadily in humid, dusty and corrosive environments, perfect for outdoor machinery, medical devices, food-grade equipment and precision electronic systems.
Product Features
Standard female thread structure for easy installation and replacement. Reliable self-aligning capability corrects mounting errors. Smooth low-friction multi-angle swing movement. Dual model and material options adapt to diverse working conditions. High precision and stable long-term operational performance.
Application Scenarios
SA12 spherical plain bearings are widely applied in industrial automation machinery, robotic arms, textile equipment, precision instruments and medium-load transmission mechanisms. SA12T fits clean, dry maintenance-free scenarios; SA12K suits conventional lubricated industrial environments, while stainless steel versions adapt to humid and corrosive working conditions.
