NTN Corporation MA5217 Cylindrical Roller Bearing

NTN MA5217 Cylindrical Roller Bearing is a single-row, straight-bore bearing from NTN’s ABMA-series, engineered to carry substantial radial loads in a compact footprint. It has a bore of 85 mm, an outer diameter of 150 mm, and an overall width of about 49.2 mm (1.937 in); the standard MA5217 configuration uses a non-separable inner ring with CN (normal) internal clearance, while the MA5217EL variant is separable, featuring a plain inner ring and an outer ring with two ribs for mounting flexibility. These dimensions and variant options—85 mm bore, 150 mm outer diameter, ~49.2 mm width, CN clearance, and separable inner-ring configurations—define its compatibility within NTN's metric cylindrical roller bearing range.
