61903 LLB C3- ABEC-5 Radial Bearing (C3 clearance) - 17mm x 30mm x 7mm
A radial bearing generally used as a hub bearing and can be used as a pivot bearing, though the MAX-type version of this bearing is better suited for suspension use. This ABEC-5 bearing features deep-groove design races, with Grade 10 balls, dual-lip, full-contact LLU seals facing outwards to withstand daily abuse of use and the elements, and lighter-contact LLB seals facing inwards to contain the 90% fill with high pressure water proof grease. C3 clearance specification is best for tighter press-fit bearing bores.
The Enduro line of bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD-15 with ceramic or stainless balls. Our bearings are always engineered with deepest groove races possible to accommodate the largest balls and feature dual-lip seals that ride in a micro-groove creating a full labyrinth to provide superior protection against the elements.
Bearings Seals
LLB Seals
Enduro's most popular light contact seal. LLB seals are comprised of Nitrile material rubber with a steel insert and ideally suited for constantly spinning bottom bracket and hub bearings. Rather than one thick 2RS seal lip rubbing on a blunt surface, LLB type utilizes two razor thin sealing lips riding in the bearing race groove. The outer lip keeps the water and contaminants out, while the inner lip retains grease for smooth function and longer intervals between servicing.
