ConMet Aftermarket hub assemblies are the most advanced wheel ends on the market, featuring ConMet wheel seals and bearings. The most advanced wheel ends on the market, including industry standard PreSet and PreSet Plus heavy duty pre-adjusted hub assemblies. For more than 20 years PreSet hubs have been the go-to wheel end for commercial vehicles in North America. By replacing your wheel ends with genuine PreSet hubs, you get the following benefits:

• Increased uptime
• Reduced labor costs
• Less potential for errors during installation
• Reduced liability

Upgrade your PreSet Hub to a PreSet Plus Hub with a PreSet Plus ConMet Spindle Nut

ConMet’s spindle nut is the market leader in both initial clamp and clamp load retention over the life of the wheel end. When compared to competitors, up to 2.5X initial clamp load is achieved upon installation and the clamp load retention exceeds 90%. The end result is maximum wheel end life.   

Additionally, the PreSet Plus Spindle Nut offers the following benefits:

• 5 year/500,000 mile warranty on Aftermarket PreSet Hubs when installed with the PreSet Plus Spindle Nut
• Once the torque is met, no adjustment is required to engage the lock ring
• It is the industry’s only nut that provides the visibility to know when the ring is positively engaged
• The PTFE coated material maximizes the clamp force when tightening the nut 
• The lock ring is in a relaxed state when engaged
• Acts as a hub puller when the hub needs be removed simplifying the removal process 
• Acts as assembly aid during installation, keeping the outboard bearing cone secure in the hub and preventing misalignment of the seal 
• The precision machined, hardened, lock washer ensures full surface contact and eliminates wear 

Seals

ConMet's specially designed multi-zone labyrinth creates superior protection and low friction, and the wide inside diameter with rubber ribs ensures proper sealing capability. ConMet's wheel seals keep harmful contaminants out and protective lubricants in, where they can work safely and smoothly.

Bearings

ConMet Bearings are superior to standard bearings because they are designed for optimized contact and reduced stress concentration, resulting in better rolling contact and less friction.

Additional benefits:

• Extended life over standard bearings
• Optimized contact and reduced stress concentration
• Improved rolling contact and reduced friction
• Lower operating temperature and improved lubrication
• More effectively withstands heavy cornering and misalignment
