INA (Schaeffler) NKIA5904-XL Needle Roller Bearing With Inner Ring

The INA NKIA5904-XL Needle Roller Bearing With Inner Ring is a compact, high-load bearing from INA (Schaeffler) that includes an integral inner ring for simple mounting and precise alignment. As part of the NKIA series, it uses needle rollers to maximize radial load capacity in a small envelope, delivering stiffness and smooth rotation in tight spaces. This single-row bearing is suited to applications where space is at a premium but reliable, low-friction rotation is required, such as compact industrial machinery and equipment that transmit radial loads. The NKIA5904-XL designation identifies the specific size variant within INA's NKIA line, reflecting the brand's precision manufacturing standards.
