Features

**LLB Seals - ;**Enduro Bearings use ;LLB type seals and CRC Marine Grease in their 440C Stainless Steel bearings, ;their ;most popular seal type, this is a Nitrile material rubber with a steel insert. Rather than the standard 2RS type seal, Enduro ;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.

440c Stainless Steel - ;Enduro only uses 440C stainless steel balls and races to provide long life and superior corrosion resistance in applications and environments that may be less than ideal. 440C has the highest strength, hardness, and wear resistance of all the standard 440-series stainless alloys with high carbon content. As expected it is also the most expensive of the 440 series alloys and requires multiple rounds of treatment processes to achieve its superior mechanical properties. Superior to the more commonly used 440A or 440B that other bearing manufacturers use interested in saving money, 440C stainless steel alloy has a higher Carbon content giving it maximum hardness and corrosion resistance after heat treatment and cryogenic treatment.
