This Nachi cylindrical bearing double row bore 55mm offers high load carrying capacities and rigidity, making it ideal for use in machine tool spindles, rolling mill stands, and large gear boxes. Its low profile section allows for increased space efficiency in tight applications. By adjusting the bearing's position during mounting, a specific radial internal clearance or preload can be achieved. Since these bearings cannot accept axial loads, they are often used in combination with thrust bearings to provide reliable support and smooth operation in high-performance machinery.
Nachi cylindrical bearing double row bore 55mm 0.005 to 0.015 radial clearance nn3011m2kc9nap4 nachi double row cylindrical roller bearings have low profile section high load carrying capacities and high rigidity. They are used for machine tool spindles rolling mill stands grinding mills and large gear boxes. A certain radial internal clearance or a given preload can be obtained by adjusting the distance the bearings are pressed up the tapered shafts during mounting. Since these bearings cannot accept axial loads they are used in combination with thrust bearings.
