WHAT IS A BEARING PROTECTOR SUPPOSED TO DO?
To protect wheel bearings from contamination by water, salt and dirt by providing and maintaining a positive hub seal. This is the only way to prevent premature bearing failure. If your current bearing protection system leaks grease, it is not maintaining a positive pressure and not providing an effective seal against outside contaminants.

The RED EYE® Bearing Protector tells you when it is full and when to add grease. When you add grease into the RED EYE®, stop when you see the "full" mark (and orange O-ring). This prevents the common mistake of over filling and causing inner-seal failure. When the red washer on the indicator is flat against the housing, it is time to add grease. If the RED EYE® indicator repeatedly tells you to add grease, this alerts you of a possible inner-seal failure that you may not realize that you had without the RED EYE®.

The RED EYE® is the only bearing protector guaranteed not to leak grease. With its patented one-piece housing and two O-ring seals, RED EYE® is the only bearing protector that can guarantee you it won't leak grease. But most importantly it assures you it is keeping dirt, water and other contaminants out of the wheel bearing area. This, combined with a spring-loaded piston, maintains a constant positive pressure on the hub, even when submerged in cold lake water.

• Guaranteed not to leak grease

What Size Do I Need?

To determine the size you need, measure the inside diameter of your hub.

• Approximately 2" - Size 1.980 (most common)
• Approximately 1 3/4" - Size 1.781
• Approximately 2 1/4" - Size 2.328
• Approximately 2 1/2" - Size 2.440
