SI12 Spherical Plain Bearing | SI12T / SI12K Stainless And Steel Types
The SI12 spherical plain bearing is a standard precision rod end joint bearing designed for medium-duty industrial automation and mechanical systems. It enables flexible multi-directional oscillation and tilting motion, featuring reliable self-aligning performance and stable low-friction operation. Available in SI12T and SI12K models with bearing steel and stainless steel options, this bearing delivers durable and cost-effective motion solutions for medium-load precision machinery.
SI12T vs SI12K | Model Differences
SI12T (Teflon Lined Type): Equipped with an integrated PTFE liner for superior self-lubricating performance and ultra-low friction. It supports dry operation with no regular grease maintenance required, making it ideal for clean, dry workshops and maintenance-free precision equipment.
SI12K (Open Lubrication Type): Standard open groove structure allows quick grease refilling and efficient heat dissipation. After lubrication, it provides stable wear resistance and consistent load capacity, suitable for long-cycle continuous operation and general medium-load industrial applications.
Material Introduction
Bearing Steel: Manufactured from high-carbon chromium bearing steel with professional heat treatment. It offers high surface hardness, excellent wear resistance and rigid structural stability, extending service life for standard indoor industrial machinery.
Stainless Steel: High-grade stainless steel features outstanding rust-proof, waterproof and anti-corrosion properties. It performs stably in humid, dusty and corrosive environments, perfect for outdoor equipment, medical devices, food-grade machinery and precision electronics.
Product Features
Standard compact structure for easy installation and replacement. Reliable self-aligning capability compensates for mounting errors. Smooth low-friction multi-angle swing movement. Dual structure and material options adapt to various working conditions. High precision and stable long-term operational performance.
Application Scenarios
SI12 spherical plain bearings are widely applied in industrial automation machinery, robotic arms, textile equipment, precision instruments, medical devices and medium-load transmission mechanisms. SI12T suits clean, dry maintenance-free scenarios; SI12K fits conventional lubricated environments, while stainless steel versions are ideal for humid and corrosive working conditions.
