61818TN

The core positioning of 61818TN is a deep groove ball bearing that can achieve both high speed and low noise performance while being compact and adaptable for medium and heavy load scenarios. It is specifically designed for medium and high-speed operations where there are requirements for installation space and a focus on quiet operation. The bearing is made of GCr15 high-carbon chromium steel body and polyamide (PA66) nylon cage. With an inner diameter of 90mm, an outer diameter of 115mm, and a width of 13mm, its compact size ensures medium and heavy load bearing capacity. The nylon cage significantly improves the noise reduction effect and wear resistance during high-speed operation, and its open design facilitates lubrication replenishment and has a low maintenance cost. It can stably withstand radial loads and bidirectional axial loads. Its low friction characteristics are suitable for medium and high-speed operation requirements. The structural strength meets the usage requirements of medium and heavy load scenarios. It is widely applied in heavy machinery transmission, large motor配套， industrial gearboxes， precision equipment shaft systems， automated production lines， and auxiliary transmission of construction machinery， providing stable， low-noise， and long-lasting rotational support for equipment operating under medium and heavy load and medium-high speed conditions.
