Product Description

The 6x12x4 Needle Bearing (also designated as 6x12x4 Precision Bearing or 6x12x4 Miniature Bearing) is a compact mechanical component designed for precision motion systems, featuring 6mm inner diameter, 12mm outer diameter, and 4mm width. Operating within temperature ranges of -30°C to +120°C, it supports radial loads up to 1.6kN with grease-lubricated steel construction. Commonly used in automotive steering systems, robotics, and miniature industrial machinery, this low-profile bearing excels in constrained spaces requiring high rotational accuracy. Its needle roller design enables reduced friction and increased load capacity compared to ball bearings, though axial load tolerance remains limited. While lacking electrical interfaces or power requirements, its maintenance-free operation and hardened steel races ensure durability in high-speed applications (max 12,000 RPM). Critical in packaging automation and medical device mechanisms where precise alignment and compact dimensions (thinner than standard bearings) are essential.
