SA30 Spherical Plain Bearing | SA30T / SA30K Steel And Stainless Steel
The SA30 spherical plain bearing is a heavy-duty female thread rod end bearing designed for medium and heavy-load industrial machinery and automation systems. It supports flexible multi-directional oscillation and tilting motion, featuring reliable self-aligning performance to compensate for mounting deviation. Available in SA30T and SA30K models with bearing steel and stainless steel options, this bearing provides low-friction, high-stability motion solutions for heavy-duty industrial applications.
SA30T vs SA30K | Model Differences
SA30T (Teflon Lined Type): Adopts built-in PTFE lining for superior self-lubrication and ultra-low friction. It allows dry operation without regular grease maintenance, ideal for clean, dry working environments and maintenance-free precision machinery.
SA30K (Open Lubrication Type): Standard open groove structure enables easy grease refilling and efficient heat dissipation. With excellent wear resistance and stable 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 delivers high surface hardness, strong wear resistance and stable structural rigidity, extending service life for standard indoor industrial equipment.
Stainless Steel: Premium stainless steel features excellent rust-proof, waterproof and anti-corrosion properties. It runs stably in humid, dusty and corrosive environments, perfect for outdoor machinery, medical devices, food-grade equipment and precision electronic systems.
Product Features
Heavy-duty female thread structure for easy installation and replacement. Reliable self-aligning capability offsets 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 operation.
Application Scenarios
SA30 spherical plain bearings are widely used in heavy-duty automation machinery, industrial robotic arms, hydraulic systems, large textile machinery and heavy-load transmission mechanisms. SA30T fits clean, dry maintenance-free scenarios; SA30K suits conventional lubricated industrial environments, while stainless steel versions work reliably in harsh humid and corrosive conditions.
