Bearing ENDURO 61902 LLU/LLB A5 15x28x7 ABEC-5, C3

The ENDURO 61902 LLU/LLB A5 is a high-precision ABEC-5 rated radial bearing, designed for smooth operation and long service life even under demanding conditions. Its deep-groove race design combined with Grade 10 precision balls ensures low rolling resistance and consistent performance.

This bearing is most commonly used as a bicycle hub bearing, but it can also be applied as a pivot bearing. For suspension systems subjected to higher axial loads, a dedicated MAX-type bearing is recommended.

The LLU/LLB seal configuration provides excellent protection and efficiency. Full-contact LLU seals on the outside protect against water, dirt, and debris, while low-friction LLB seals on the inside retain a 90% fill of high-pressure waterproof grease, ensuring smooth rotation and extended bearing life.

The C3 clearance specification is well suited for applications involving thermal expansion or tighter press-fit bearing bores. Like all ENDURO bearings, this model is engineered with the deepest possible race grooves and dual-lip labyrinth seals riding in a micro-groove, providing superior protection against the elements.
