61806 LLU/LLB - ABEC-5 Radial Bearing (CN Clearance) - 30mm x 42mm x 7mm Radial Bottom Bracket Bearing featuring 52100 High-Carbon Chromium alloy races paired with grade 5 Balls with 90% fill, high-pressure, water-proof grease. Designed specifically for bicycle applications, the LLU/LLB seal combination on these bearings utilizes a more protective gray LLU seal facing outward, towards the elements, to reduce contamination from water or dirt, while the lighter-contact (less seal-drag) black LLB seals facing inward keep the grease where it belongs. The most common use for this bearing is as a direct replacement bearing for Shimano external cup BBs when using the plastic Shimano bearing insert. If you wish to avoid using the plastic insert MR 2437 is the correct bearing for the job The Enduro line of bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD15 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.

61808 LLB- ABEC-5 Radial Bearing (C3 Clearance) - 40mm x 52mm x 7mm Radial bearing has been used as a drive-side rear hub bearing by Industry Nine and White andustries and has 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, and LLB seals and0% fill with high pressure water proof grease to withstand daily abuse of use and the elements. The Enduro line of bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD15 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.

688 LLB A5 - ABEC-5 Radial Bearing (CN Clearance) - 8mm x 16mm x 5mm This radial bearing has been used as a hub bearing and as a pivot bearing though the MAX-type version of this bearing is better suited for suspension use. This ABEC-5 radial bearing features 52100 High-Carbon Chromium alloy races paired with Grade 10 balls and dual-lip labyrinth (LLB) seals to withstand the outside elements, and to contain the 90% fill Mobil XHP 222 high pressure water proof synthetic 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 XD15 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.

699 LLB A5 - ABEC-5 Radial Bearing (C3 Clearance) - 9mm x 20mm x 6mm Radial bearing generally used as a hub bearing for some quick-release hub designs, as a pedal 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, LLB seals and 90% fill with high pressure water proof grease to withstand daily abuse of use and the elements.
