SA18 Spherical Plain Bearing | SA18T / SA18K Steel And Stainless Steel
The SA18 spherical plain bearing is a heavy-duty female thread rod end bearing engineered for medium and heavy-duty industrial machinery and automation systems. It delivers flexible multi-directional oscillation and tilting motion with premium self-aligning performance, perfectly compensating for installation and mounting errors. Available in SA18T and SA18K configurations in bearing steel and stainless steel, this bearing offers low-friction, durable and cost-effective motion solutions for heavy-load industrial operations.
SA18T vs SA18K | Model Differences
SA18T (Teflon Lined Type): Features integrated PTFE lining with excellent self-lubricating properties and ultra-low friction. It supports full dry operation without regular grease maintenance, ideal for clean, dry workshops and maintenance-free precision industrial machinery.
SA18K (Open Lubrication Type): Adopts a standard open groove structure for easy grease refilling and efficient heat dissipation. After professional lubrication, it ensures stable wear resistance and consistent heavy-load capacity, suitable for long-term continuous cyclic operation and heavy-duty industrial scenarios.
Material Introduction
Bearing Steel: Constructed from high-carbon chromium bearing steel with precise heat treatment. It boasts high surface hardness, exceptional wear resistance and stable structural rigidity, extending service life for standard indoor industrial equipment.
Stainless Steel: Premium stainless steel provides outstanding rust-proof, waterproof and anti-corrosion performance. It operates steadily 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 simple installation and replacement. Reliable self-aligning capability offsets mounting deviation. 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
SA18 spherical plain bearings are widely used in heavy-duty automation machinery, industrial robotic arms, hydraulic systems, large textile machinery and heavy-load transmission mechanisms. SA18T is suitable for clean, dry maintenance-free scenarios; SA18K fits conventional lubricated industrial environments, while stainless steel versions deliver stable performance in humid and corrosive working conditions.
