61804TN/C2

61804TN/C2 is a single-row deep groove ball bearing equipped with polyamide (PA66) nylon inner rings and adheres to the C2-level clearance standard. Its core function is to serve as a precision general-purpose transmission component for applications requiring advanced performance in terms of rotational accuracy, low noise, and speed capability within a compact installation space. It is specifically designed for small and medium-sized equipment with high rotational speed, medium load, and strict control of operating clearance. It maintains the compact size of the 61804 series (20mm inner diameter, 32mm outer diameter, 7mm width), with the bearing body made of GCr15 high-carbon chromium bearing steel and a rolling body-guided nylon TN inner ring. This design reduces operating friction and noise while enhancing transmission smoothness, meeting the long-term continuous operation requirements of the equipment. The C2-level radial clearance (less than the standard clearance) ensures stronger rigidity and smaller runout during high-speed operation, superior running accuracy, and the ability to stably withstand radial loads and small bidirectional axial loads. It also has slight self-aligning capability and can accommodate minor deviations during installation. Its standardized size offers strong interchangeability, facilitating procurement and replacement, and the open design supports the addition of lubricating grease as needed to extend the service life. It is widely applicable in scenarios such as small precision industrial motors, high-speed power tools, precision instruments, small automation equipment, electronic equipment transmission structures, and high-end auxiliary components of automobiles, especially suitable for precision transmission structures with higher requirements for operating clearance, noise control, and transmission accuracy.
