Pro-Torq axle spindle nuts provide accurate bearing adjustment, increasing wheel end life. Pro-Torq easily secures wheel bearings in precise position the first time and eliminates jamming, juggling and time-consuming positioning of multiple nut assemblies. Longer Tread Life. Pro-Torq delivers the adjustment precision which experts agree is needed to maximize radial tire life. Pro-Torq axle spindle nuts control axial motion, holding bearing end play near zero while maintaining exact cup and cone alignment on the spindle. This is good news for radial tires. Fleets save tires, wheels track truer. Extended Wheel Seal And Bearing Service. Pro-Torq supports seal, ball bearing and axle manufacturers’ specifications. With Pro-Torq’s tight control on wheel bearing adjustment, fleets minimize premature seal failure and improve extended seal and brake lining programs. Pro-Torq is also your choice when using new semi-fluid and synthetic grease lubricants to precisely set bearings for lubed-for-life wheel ends. Pro-Torq compensates for normal bearing wear, permitting precise .001″ takeup increments at scheduled preventative maintenance intervals. This keeps bearings properly aligned, running cooler and lasting longer. Improve ABS. Pro-Torq’s reliable low end play bearing adjustment and axial motion control helps assure accurate wheel end sensor monitoring of wheel speeds on antilock braking systems.
