Product Highlights

Discover Wheel Seal

Hub-Installed Unitized Design High Performance

Minimizing Costs Through Extended Service Intervals.
Discover® wheel seals are designed for the long haul carrier seeking high performance wheel end components. Discover® seals are an excellent choice for fleets running outboard-mounted brake drums that allow brake changes without seal replacement. The long life characteristics of this wheel seal, proven in testing that exceeds competitive products' performance by five times, make it the industry choice for performance driven fleet managers.

Increase The Performance Expectations Of Wheel Ends.
The Discover® wheel seal features a high temperature elastomeric co-polymer sealing element combined with Teflon®. The revolutionary design incorporates hydrodynamic "pumping" features to keep the lubricant where it is intended to be.

Maintain The Lubricant's Integrity To Lengthen The Life Of The Seal.
The premium sealing element is protected by a four-zone labyrinth to provide unmatched contaminant exclusion and performance.

Have Complete Confidence During The Installation Stage.
The Discover® wheel seal's piloted entry allows an easy and square installation every time. The double steel case is the impact point for the tool head to maintain the internal geometries.

Reduce Removal Time And Effort Without Special Tools Or Component Damage.
The Discover® seal consists of a bonded, ribbed rubber OD and ID for easier removals, yet STEMCO's patented "SMART" anti-rotation features insure positive positioning and locking of the seal to the spindle.

Voyager Wheel Seal

Revolutionary Hub-Installed Unitized Wheel Seal That Will Minimize Your Maintenance Costs.
The Voyager® wheel seal is designed for regional route trucks, city delivery and coach applications. Rugged design, simple installation and proven performance make Voyager® the right choice for fleets looking for a superior brake job-to-brake job seal. In the everyday stop-and-go traffic environment these vehicles experience, the Voyager® wheel seal is the best value.

Easier And Faster Installations.
The Voyager® wheel seal features a bonded rubber OD and piloted entry ensuring an easy and square installation. The ribbed rubber OD also forms a superior seal between the seal case and the hub bore. STEMCO's unique seal tool ribs ensure the proper hub bore alignment preventing improper installation into the hub.

Reduce Premature Failures And Rework.
The Voyager® wheel seal utilizes a 4-zone labyrinth contaminant exclusion system. This technology is incorporated into a fully-unitized hub-installed seal.

Avoid Seal Damage Upon Installation.
The Voyager® wheel seal's double steel case construction allows positive hub installation without warping or bending the seal.

Increase Reliability Through Superior Material And Design.
The temperature-resistant nitrile polymer with hydrodynamic "pumping" features keeps the lubricant where it is intended to be.

Eliminate "Pry-Bar" Removal And Adjacent Component Damage.
The Voyager® wheel seal's bonded rubber ID and OD allow for easier removal, yet STEMCO's patented anti-rotation "SMART" features lock the ID surface in place.

Grit Guard Wheel Seal

Two-piece Hub Seal design for improved dirt exclusion
Always rough and ready, Grit Guard® hub seal has endured more than forty years of dirty, unfriendly road environments that destroy wheel end components. So with this forty year plus track record of performance, Grit Guard® endures where other hub seals fail, and is still the choice for fleets working in grueling environments.

Two-Piece Wheel Seal Design Protects Against Contamination
Designed to reduce maintenance and prevent unnecessary wear on expensive spindles, the Grit Guard® two-piece hub seal design provides effective and lasting protection against contamination.

A two-piece design, the Grit Guard® wheel seal features a spindle-installed deflector ring. This provides dirt exclusion for extended seal performance and insures a new surface for the sealing lip. The deflector ring can often repair a damaged or worn spindle shoulder.

The hub-installed metal case seal provides a metal-to-metal continuous press fit between the seal and hub. In addition, a blue coating is applied to the seal to prevent minor seepage between the seal and hub.

Survive Severe Duty And Temperature Applications
Grit Guard®'s Elasto-Leather sealing lip provides an excellent temperature range from -65ºF to +250ºF remaining flexible and durable. Also, the lip rotates on the deflector ring for improved heat dissipation and less lip travel per wheel rotation.

Grit Guard® is available for the rugged, severe duty applications that other wheel seals are not available for.
