Product Description

The 4x12x4 Needle Roller Bearing is a high-precision mechanical component engineered for applications requiring minimal radial space and optimal load distribution. With dimensions of 4mm inner diameter, 12mm outer diameter, and 4mm width, these Precision 4x12x4 Bearings are ideal for integration into compact assemblies such as gearboxes, automotive transmissions, and robotics systems. Designed to operate within a temperature range of -30°C to 120°C, they support rotational speeds up to 15,000 RPM while maintaining radial load capacities of 1.8 kN. The 4x12x4 High-Precision Bearings feature a cage-guided roller configuration for smooth operation, reducing friction and wear. Widely used in automation, aerospace, and medical equipment, their advantages include exceptional durability, low noise, and minimal maintenance needs. However, they require precise alignment during installation and are less suitable for axial loads. No electrical interfaces are incorporated, as these purely mechanical components rely on direct mounting within motion systems.
