SKF 2305ETN9/C3 is a double-row self-aligning ball bearing with an open design (no seals) and C3 internal clearance for applications with higher operating temperatures, shaft expansion, or fits that reduce internal clearance. The two rows of balls run in a spherical outer-ring raceway, allowing the bearing to self-align and tolerate misalignment or shaft deflection. Low friction design suitable for higher speeds, high radial loads, and moderate axial loads in both directions.
