I-71231

The I - 71200 series self - aligning ball bearings are distinctively designed for mounting on shoulderless shafts. One side of the inner ring is extended and features drilled and tapped holes. This allows for set screw mounting and locking to the shaft, ensuring a secure fit. With a spherical outer ring raceway, it can self - align up to 2 - 3 degrees, compensating for shaft misalignment effectively. Made of high - quality chrome steel, it offers good radial load - bearing capacity and can handle moderate axial loads from both directions. This series is widely used in applications where shaft misalignment is likely to occur, such as in certain types of conveyor systems and small - scale industrial machinery.
