Product Description

The 12x18x4 bearing is a high-performance precision bearing designed for applications requiring compact dimensions and exceptional accuracy. This miniature precision bearing operates within a wide temperature range of -30°C to +120°C and supports radial loads up to 120N, ideal for robotics, medical equipment, and aerospace systems. Featuring a 12mm inner diameter, 18mm outer diameter, and 4mm thickness, it integrates seamlessly with servo motors, encoders, and micro-mechanical assemblies. The bearing's stainless steel construction ensures low friction and corrosion resistance, while its shielded design enhances dust protection. Although optimized for minimal maintenance, its compact size may require specialized tools for installation. Compatible with lubrication options for extended lifespan, this precision component achieves ultra-low noise levels (<18dB) at speeds up to 12,000 RPM.
