Our bearing seals are designed and tested in house for maximum performance. We never use any “off the shelf” parts, every component of our bearings is considered for performance, weight, and durability, and this includes the seals. For this reason, we have 5 types of seals for the different types of specialized bearings that we offer. All of our seals can be removed for service by gently prying from the inside with a small blade and carefully lifting the seals from the inner and outer grooves.
Enduro LLB Type Seals: Our most popular seal type, this is a Nitrile material rubber with a steel insert. Rather than the standard 2RS type seal, we go a step further by machining a groove into the inner race where the seal can rotate with better efficiency and less rolling resistance. Rather than one thick seal lip rubbing on a blunt surface, LLB type utilizes two razor thin sealing lips riding in the groove with light contact. The outside lip keeps the water and contaminates out, while the inner seal retains the grease for smooth function and long intervals between servicing.
