SKF 127TN9 self-aligning ball bearing (12xx / 13xx / 22xx). Double-row self-aligning ball bearing with a spherical outer-ring raceway that tolerates static shaft-to-housing misalignment up to 3° without affecting bearing life. Series 12xx (light), 13xx (medium) and 22xx (wide) per ISO 15. Suitable for long line-shafts on marine deck machinery and conveyors where accurate housing alignment cannot be guaranteed. Standard cage nylon PA66 or fabric-reinforced phenolic.
