SKF 619/9-2Z Deep Groove Ball Bearing

Description

The SKF 619/9-2Z is a high-precision, single-row deep groove ball bearing. It is a versatile and popular choice for a wide variety of applications due to its simple design, non-separability, and suitability for high speeds. The metal shields on both sides of the bearing protect the raceways from dirt and debris, while retaining the factory-filled grease for maintenance-free operation.

FAQ

The '2Z' suffix indicates that the bearing is equipped with a pressed sheet steel shield on both sides. These shields are non-contact, meaning they do not touch the inner ring, which results in very low friction while still providing effective protection against larger contaminant particles.

Yes, deep groove ball bearings, especially with non-contact shields like the '2Z' type, are well-suited for high and very high-speed operations due to their low frictional torque.

SKF '2Z' bearings are typically supplied lubricated for life with a specific type and quantity of grease and do not require re-lubrication under normal operating conditions. Attempting to add more grease can damage the shields and lead to premature failure.
