SI22 Spherical Plain Bearing | SI22T / SI22K Stainless And Steel Types
The SI22 spherical plain bearing is a heavy-duty rod end joint bearing widely used in medium and heavy industrial machinery and automation systems. It provides flexible multi-directional oscillation and tilting motion with reliable self-aligning performance and low-friction stable operation. Available in SI22T and SI22K models with bearing steel and stainless steel options, this bearing offers durable, cost-effective motion solutions for heavy-load industrial equipment.
SI22T vs SI22K | Model Differences
SI22T (Teflon Lined Type): Built-in PTFE liner provides excellent self-lubricating performance and ultra-low friction. It supports dry operation without regular grease maintenance, ideal for clean, dry working environments and maintenance-free precision machinery applications.
SI22K (Open Lubrication Type): Standard open groove structure enables 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: Manufactured from high-carbon chromium bearing steel with professional heat treatment. It features high surface hardness, outstanding wear resistance and stable structural rigidity, ensuring long service life for conventional indoor industrial equipment.
Stainless Steel: Premium stainless steel delivers superior 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 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 operational performance.
Application Scenarios
SI22 spherical plain bearings are commonly applied in heavy-duty automation machinery, industrial robotic arms, hydraulic systems, large textile machinery and heavy-load transmission mechanisms. SI22T fits clean, dry maintenance-free scenarios; SI22K suits standard lubricated industrial environments, while stainless steel versions work reliably in humid and corrosive working conditions.
