NSK guarantees the high quality of all of their products by repeated, rigorous bench testing, and other checks that take full advantage of their cutting-edge technology, which only the major bearing manufacturers can offer. Product Features:Original Equipment QualityPremium modified bearing steelOptimized sealing systemsSpecific roller and raceway profiles Installation Note: Some bearings contain active wheel sensors. These wheel sensors normally work together with magnetic ABS sensor rings. These sensor rings have a magnetic north and south poles lying next to each other in its circumference. These magnetic poles must always lie opposite the wheel sensor. If, the wheel bearing is installed improperly, the system wheel sensor and magnetic sensor gear cannot supply a signal making the ABS system inoperable. The ATE Test Card for Magnetic Sensor Gears will assist in prevention of these errors. PN# 760130 ATE
