The NKE 3311-B-2Z-TV is a high-quality double row angular contact ball bearing, engineered for applications requiring high radial and axial loads. It features a 55 mm bore diameter, 120 mm outer diameter, and 49.2 mm width. The '2Z' designation indicates that the bearing is equipped with two non-contacting shields on both sides, providing effective protection against contaminants while allowing for high-speed operation. The 'TV' suffix denotes a glass fibre reinforced polyamide cage, which offers excellent sliding properties, low friction, and reduced weight. This robust bearing is suitable for various industrial machinery applications where durability and performance are critical.
