SA22 Spherical Plain Bearing | SA22T / SA22K Steel And Stainless Steel
The SA22 spherical plain bearing is a heavy-duty female thread rod end bearing designed for medium and heavy industrial machinery and automation systems. It provides flexible multi-directional oscillation and tilting movement with reliable self-aligning performance to compensate for mounting deviation. Available in SA22T and SA22K models with bearing steel and stainless steel options, this bearing delivers low-friction, stable motion solutions for heavy-load industrial equipment.
SA22T vs SA22K | Model Differences
SA22T (Teflon Lined Type): Features a built-in PTFE liner with excellent self-lubricating properties and ultra-low friction. It supports dry operation without regular grease maintenance, ideal for clean, dry working environments and maintenance-free precision machinery applications.
SA22K (Open Lubrication Type): Standard open groove structure allows easy grease refilling and efficient heat dissipation. With stable wear resistance and consistent heavy-load performance after lubrication, it is suitable for long-term continuous operation and general heavy-duty industrial scenarios.
Material Introduction
Bearing Steel: Made of high-carbon chromium bearing steel with professional heat treatment. It offers high surface hardness, outstanding wear resistance and stable structural rigidity, ensuring long service life for conventional indoor industrial equipment.
Stainless Steel: Premium stainless steel provides excellent rust-proof, waterproof and anti-corrosion performance. It operates stably in humid, dusty and corrosive environments, perfect for outdoor machinery, medical devices, food-grade equipment and precision electronic systems.
Product Features
Robust heavy-duty female thread structure for easy installation and replacement. Excellent self-aligning capability compensates for mounting deviation. Smooth low-friction multi-angle swing movement. Dual structure and material options adapt to diverse working conditions. High precision and stable long-term operation.
Application Scenarios
SA22 spherical plain bearings are widely used in heavy-duty automation machinery, industrial robotic arms, hydraulic systems, large textile machinery and heavy-load transmission mechanisms. SA22T fits clean, dry maintenance-free scenarios; SA22K suits standard lubricated industrial environments, while stainless steel versions work reliably in humid and corrosive working conditions.
