Bearing Enduro 61001 LLU/LLB A5 12x28x8 ABEC-5, CN

The Enduro 61001 LLU/LLB A5 is a high-precision ABEC-5 rated radial bearing designed for smooth and durable performance in bicycle applications. Its deep-groove race design combined with Grade 10 precision balls ensures low rolling resistance and reliable operation under continuous load.

This bearing is commonly used as a hub bearing in certain quick-release hub designs, but it can also be applied as a pivot bearing. For suspension systems exposed 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 CN clearance specification makes this bearing ideal for looser press-fit bearing bores. Like all Enduro bearings, it is engineered with the deepest possible race grooves and dual-lip labyrinth seals riding in a micro-groove, delivering superior protection against the elements.
