61903 LLU/LLB A5 – ABEC-5 Radial Bearing (CN Clearance) – 17mm x 30mm x 7mm
Radial bearing generally used as a hub bearing, bottom bracket bearing for some older square taper BBs, 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. CN clearance specification is best for looser 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 deep groove races to accommodate the largest balls possible. All of our standard bearings feature dual-lip seals that ride in a micro groove creating a full labyrinth to provide ultimate protection against the elements.
