88509 (209FFS) BKL Sealed Deep Groove Ball Bearing with Extended Inners 45mm inside x 85mm outside x 21/27mm wide Sealed Base Width (A): 58mmAn extended inner bearing is designed with a longer inner race, which extends beyond the typical dimensions of a standard bearing. This design allows for improved load distribution, increased stability, and enhanced performance in applications where the standard bearing configuration may not provide sufficient support. Extended inner bearings are commonly used in machinery, automotive, or industrial applications where space constraints or specific
