Engineered for precision applications where space is at a premium and weight reduction is critical, the 6919-ZZ is a high-performance thin-section deep groove ball bearing. Featuring dual pressed-steel shields (ZZ), it guards internal raceways against dust contamination while retaining factory-filled lubricant. The non-contact design of these metal shields minimizes rotational drag and heat generation, making it an ideal choice for 95mm shaft configurations including industrial automation, large electric motors, and rotary tables.
