Name: China 61902-2ZTN Manufacturers Suppliers Factory - Customized 61902-2ZTN Made in China
Brand: TUOCHENG Bearing
SKU: 286590246

61902-2ZTN is a composite single-row deep groove ball bearing with both side press-in steel dust covers + outer ring stop slots + precise tolerance design. Its core function is to provide "dust protection + axial positioning + high precision operation" integrated compact support for rotating components of small and medium-sized high-speed precision equipment. With a compact structure of 15mm inner diameter, 28mm outer diameter, and 7mm width, it precisely fits the installation space constraints and simultaneously meets the requirements of dust sealing, axial fixation, and high-speed stability in harsh conditions. The model suffix "2ZTN" integrates three core characteristics: the double-sided press-in steel dust covers can effectively prevent dust, debris, and other solid impurities from entering, protecting the internal raceways and steel balls, while not increasing the operating resistance, suitable for high-speed conditions; the outer ring stop slot design can cooperate with the stop ring to achieve precise axial positioning, limiting the axial movement of the bearing, simplifying the axial fixation structure of the equipment; "TN" represents high precision tolerance and optimized cage design, further improving the operating accuracy and stability. The bearing is made of high-carbon chromium bearing steel and is paired with steel plate press-in cages, featuring excellent wear resistance and fatigue resistance. It can stably withstand radial loads and small bidirectional axial loads, with a basic rated dynamic load of 4.36kN and a basic rated static load of 2.24kN. The grease lubrication reference speed is 56000r/min, and the limit speed is 34000r/min. The finely ground raceways and the optimized design of the composite structure ensure low noise, low vibration, and high precision operation under high-speed conditions. It is easy to install and has strong interchangeability, widely applicable to various types of small and medium-sized transmission mechanisms with comprehensive dust protection, positioning, and high-speed operation requirements, providing an integrated, long-lasting, and reliable rotational support solution.
