SI25 Spherical Plain Bearing | SI25T / SI25K Stainless And Steel Types
The SI25 spherical plain bearing is a heavy-duty rod end joint bearing designed for medium and heavy industrial machinery and automation systems. It supports flexible multi-directional oscillation and tilting movement, delivering reliable self-aligning performance and stable low-friction operation. Available in SI25T and SI25K models with bearing steel and stainless steel options, this bearing provides durable, cost-effective motion solutions for heavy-load industrial equipment.
SI25T vs SI25K | Model Differences
SI25T (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, making it ideal for clean, dry working environments and maintenance-free precision machinery applications.
SI25K (Open Lubrication Type): Standard open groove structure allows convenient grease refilling and efficient heat dissipation. After lubrication, it offers stable wear resistance and consistent heavy-load performance, 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 provides high surface hardness, outstanding wear resistance and stable structural rigidity, extending service life for conventional indoor industrial equipment.
Stainless Steel: Premium stainless steel boasts 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. Superior 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
SI25 spherical plain bearings are widely used in heavy-duty automation machinery, industrial robotic arms, hydraulic systems, large textile machinery and heavy-load transmission mechanisms. SI25T fits clean, dry maintenance-free scenarios; SI25K suits standard lubricated industrial environments, while stainless steel versions deliver reliable performance in humid and corrosive working conditions.
