Check grease levels at a glance with the blue auto-check ring. Stainless steel Bearing Buddies maintain light grease pressure inside the hub to protect your bearings, even when submerged, while the zerk fitting makes adding grease quick and easy.
Features:
Specs:
Replace your existing grease cap with a Bearing Buddy for an easy way to monitor and maintain the grease level in your axle hub. Use a grease gun to add grease through the zerk fitting. As the hub fills, the spring-loaded piston moves outward, raising the blue auto-check ring. When the blue ring is 1/8" above the steel retaining ring, the hub is properly filled.
The O-ring inside the barrel of the Bearing Buddy maintains a seal from the outside. The pressurized grease inside the hub helps prevent water from entering and contaminating the grease. Bearing Buddy also includes an automatic pressure-relief feature to help prevent overfilling and damage to the inner seal. Once the hub is full, excess grease seeps around the edges of the piston and into the barrel while the blue auto-check ring remains raised.
Check the blue auto-check ring to see when it's time to add grease. If the ring has receded below or is flush with the steel retaining ring, more grease is needed. If the lip of the blue ring is 1/8" above the steel retaining ring, the hub is properly filled.
