Pro-Torq® Axle Spindle Nuts

An Axle Spindle Nut System for Today's Fleets.

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 controls 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, 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.

Pro-Torq provides safety, extended seal life, extended bearing life and extended tire life through:

• - Wheel bearing adjustment accuracy of .000" to .003" end play
• - Infinite locking positions
• - Twice the number of threads to firmly hold bearings
• - Controlled axial motion - avoids extremes of pre-load and excessive bearing end play

Ask any mechanic...
Precisely designed seals, bearings and hubs are only as good as the precision with which they are assembled as an integral unit. That's where the Pro-Torq Axle Spindle Nut comes in. Proper bearing adjustment could be the singularly most critical aspect of wheel end performance. The effect on all wheel end components, seals, bearings and tires is highly impacted by improperly adjusted bearings. Properly installed, the Pro-Torq is designed to deliver precise wheel bearing adjustment.
