Koyo 5760 Tapered Roller Bearing 519C/5190 95 x 200 x 67 mm 22319 RZW33C3

A spherical roller bearing from Koyo, manufactured in Japan, presented in its original Koyo Bearings branded box. The outer ring is visibly stamped with the Koyo name and Japan origin markings. Based on box dimensions and visible partial markings, the most consistent identification is part number 22319 RZW33C3, a double-row spherical roller bearing with a 95 mm bore, 200 mm outer diameter, and 67 mm width. Note: the full part number could not be confirmed from visible markings in the provided photos due to plastic wrap obscuring the ring; manual verification of the box end label or bearing ring marking is required before publishing.

The 22319 series spherical roller bearing is designed to accommodate high radial loads and moderate bidirectional axial loads. The double-row design with barrel-shaped rollers provides self-aligning capability, allowing for up to approximately 1.5 degrees of shaft misalignment. Koyo, now marketed under the JTEKT brand, is a Japanese premium-tier bearing manufacturer with a long history of producing bearings to strict dimensional and quality standards. The W33 designation indicates a lubrication groove and holes in the outer ring for in-housing relubrication. C3 internal clearance, if confirmed, indicates a wider-than-normal running clearance suited for interference-fit applications or elevated operating temperatures. The bearing appears to be in new or uninstalled condition, still in its original manufacturer packaging.
