61804TN

The 61804TN is a single-row deep groove ball bearing from the ultra-thin series. Its core function is to be suitable for narrow installation spaces and to meet the requirements for smooth operation and wear resistance in general-purpose transmission components. It features an injection-molded nylon 6,6 cage as its core characteristic, specifically designed for high-performance, compact basic components for small and medium-sized high-speed rotating equipment. It retains the compact dimensions of the 61804 series, with an inner diameter of 20mm, an outer diameter of 32mm, and a width of 7mm. The bearing body is made of bearing steel, and is paired with a rolling body-guided nylon TN cage. Compared to traditional steel plate stamping cages, it can further reduce friction and noise during operation, while enhancing the smoothness of rotation. It meets the requirements for long-term continuous operation of equipment. This bearing can withstand radial loads and a small amount of bidirectional axial loads. It has a reference rotational speed of 45,000 r/min and an ultimate rotational speed of 28,000 r/min. It also has slight self-aligning capability, ensuring stable operation even with minor installation deviations. Its standardized size provides strong interchangeability, making procurement and replacement convenient. The design of the nylon cage also takes into account lightweight and cost controllability, widely applicable to small industrial motors, household appliances, electric tools, etc., and can also match precision instruments, small automation equipment, etc., which have high requirements for operation noise and stability. It is a core transmission component for small and medium-sized equipment that balances practicality and adaptability.
