This Nachi cylindrical bearing double row bore is designed for high-load applications, offering a low profile section, high load carrying capacities, and high rigidity. Suitable for use in machine tool spindles, rolling mill stands, grinding mills, and large gear boxes, this bearing provides a certain radial internal clearance or preload that can be adjusted during mounting. Its compact design makes it ideal for space-constrained environments, and its high performance capabilities ensure reliable operation in demanding industrial settings.
Nachi cylindrical bearing double row bore 105mm 0.040 to 0.060 radial clearance nn3021m2kc1nap4 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.
