Nachi is a supplier of original equipment wheel bearings, hubs and seals to many leading Japanese automakers. Product Features:Manufactured with high carbon chromium bearing steel or case hardening steelHeat-treated to an appropriate hardness to attain optimum resistance to rolling fatigueBearing surfaces are ground to a very high accuracy using special machine toolsOE form, fit and function 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
