Name: China 619/4-Z Manufacturers Suppliers Factory - Customized 619/4-Z Made in China
Brand: TUOCHENG Bearing
SKU: 286305771

619/4-Z, as a small precision deep groove ball bearing, its core function is to provide stable rotational support with high speed and low friction for small equipment with limited space and clear requirements for unilateral dust protection. With a 4mm inner diameter, 11mm outer diameter, and a compact size of 4mm, it precisely fits the assembly scenarios that require both space utilization and dust protection reliability. The core components are made of high-carbon chromium bearing steel (GCr15), and are combined with steel plate stamping cages and Z-type single-sided stamping dust covers. This design can effectively prevent dust and tiny impurities from entering the bearing from one side, reducing lubricant leakage and internal part wear, while maintaining a streamlined structure and ease of installation. Special low-viscosity lithium-based lubricating grease is pre-filled to achieve low-noise operation, capable of withstanding radial loads and small to moderate bidirectional axial loads, suitable for precision applications with light to medium loads. It is widely used in miniature motors, precision instruments and meters, sensors, portable electronic devices, medical micro-instruments, small optical equipment, miniature pumps and valves, high-end toy core components, etc., providing long-term support for small rotating structures that offer both dust protection and stable operation.
