61801TN

61801TN is a universal single-row deep groove ball bearing with a cage. Its core positioning is a high-speed precision general-purpose bearing suitable for small and medium-sized equipment. With a compact size of 12mm inner diameter, 21mm outer diameter, and 5mm width, and a lightweight design, it can be flexibly inserted into mechanical installation cavities with limited space without increasing the load on the equipment. The suffix "TN" corresponds to the TN type polyamide 66 (nylon) injection molded cage (ball centering). It is lightweight, high in strength, and has good wear resistance, which can effectively guide the steel balls to rotate, reduce friction and running noise. Combined with GCr15 high-carbon chromium bearing steel or 440C stainless steel materials, it further enhances the stability and service life under high-speed conditions. Under oil lubrication, its rated rotational speed can reach 70,000 r/min, capable of stably bearing radial loads and coping with some bidirectional axial loads. It meets the comprehensive requirements of small and medium-sized equipment for speed, precision, and low noise. The open design is convenient for subsequent lubrication supplementation as needed, and it is suitable for a temperature range of -30°C to 120°C, capable of handling various conventional and mild complex working environments. At the same time, it is compatible with international brand bearings of the same specification, with strong interchangeability, reducing equipment assembly and replacement costs. It is widely applicable to general machinery, small and medium-sized motors, office equipment, household appliances, precision instruments, automotive electronics, automation equipment, medical device small components, etc., and is a universal precision bearing that combines precision, stability, and economy.
