6121TN

The 6121TN is a single-row deep groove ball bearing with a nylon inner ring. Its core function is to serve as a universal precision rotating support component suitable for medium and heavy-duty scenarios. With an inner diameter of 105mm, an outer diameter of 160mm, and an adaptable size of 26mm, it features a classic combination of GCr15 high-carbon chromium bearing steel and PA66 nylon inner ring. This design not only offers the basic advantages of a simple structure and convenient maintenance of deep groove ball bearings, but also enhances the noise reduction effect and wear resistance during operation through the nylon inner ring. It can stably withstand radial loads and small bidirectional axial loads, and is suitable for common industrial conditions and some scenarios with requirements for smooth operation. It is typically pre-filled with lithium-based composite lubricating grease at the factory, featuring a low friction coefficient and the ability to replenish lubricating media as needed. It can meet the high-speed operation requirements of equipment such as motors and machine tool gearboxes, and is also suitable for scenarios with basic requirements for load and stability such as agricultural machinery, general mechanical transmission components, and auxiliary transmission structures of automated production lines and small and medium-sized precision equipment shaft systems. It provides a cost-effective, reliable, and highly adaptable rotational support solution for various equipment, balancing the adaptability to working conditions and usage economy.
