LLB 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.
Stainless Steel Bearings Enduro Bearings manufactures some series of bearings using 440C stainless steel balls and races. This material provides maximum corrosion resistance in applications and environments where critical. Depending on the application, they are designed to ABEC-3 or ABEC-5 tolerances. Stainless steel has 20% less load capacity than the 52100 chromium steel, used in most of our bearings, but with far superior corrosion resistance. When the rain wont go away, and your bicycle is more often used as a boat rather than a land craft, you may want to consider 440C stainless steel bearings. While a little softer than chromium bearing steel, 440C stainless steel is a good alternative in constant wet conditions, or where sweat becomes a problem such as headset bearings. Enduro Bearings uses LLB type seals and CRC Marine Grease in these bearings to additionally water proof against the elements.
