SI30 Spherical Plain Bearing | SI30T / SI30K Stainless And Steel Types
The SI30 spherical plain bearing is a heavy-duty rod end joint bearing designed for medium to heavy industrial machinery and automation systems. It delivers flexible multi-directional oscillation and tilting motion with superior self-aligning performance and stable low-friction operation. Offered in SI30T and SI30K models with bearing steel and stainless steel options, this bearing provides reliable, cost-effective motion solutions for heavy-load industrial equipment.
SI30T vs SI30K | Model Differences
SI30T (Teflon Lined Type): Features a built-in PTFE liner with premium self-lubricating properties and ultra-low friction. It supports dry running operation without regular grease maintenance, ideal for clean, dry workshops and maintenance-free precision machinery applications.
SI30K (Open Lubrication Type): Standard open groove structure enables convenient 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 working scenarios.
Material Introduction
Bearing Steel: Made of high-carbon chromium bearing steel with professional heat treatment. It achieves high surface hardness, outstanding wear resistance and stable structural rigidity, ensuring long service life for conventional indoor industrial equipment.
Stainless Steel: High-grade stainless steel offers 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 structure for easy installation and replacement. Reliable 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
SI30 spherical plain bearings are widely used in heavy-duty automation machinery, industrial robotic arms, hydraulic systems, large textile machinery and heavy-load transmission mechanisms. SI30T fits clean, dry maintenance-free scenarios; SI30K suits standard lubricated industrial environments, while stainless steel versions work reliably in humid and corrosive working conditions.
