1309 ETN9
BWK
BWK-1309-ETN9
1309 ETN9 is a self-aligning ball bearing with 45 mm bore, 100 mm outside diameter and 25 mm width. Two rows of balls share a spherical outer-ring raceway, allowing the bearing to accommodate shaft deflection and mounting misalignment. The open design requires a suitable external sealing arrangement.
