Bearing ENDURO 61803 LLU/LLB A5 17x26x5 ABEC-5, C3

The ENDURO 61803 LLU/LLB A5 is a high-quality ABEC-5 rated radial bearing designed for smooth performance and long service life under demanding conditions. Its deep-groove race design combined with Grade 10 precision balls ensures low rolling resistance and excellent durability.

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

The LLU/LLB seal configuration offers an optimal balance between protection and efficiency. Full-contact LLU seals on the outside protect against water, mud, 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 makes this bearing ideal for tighter press-fit bearing bores. ENDURO bearings are engineered with the deepest possible race grooves to accommodate larger balls and feature dual-lip labyrinth seals riding in a micro-groove, delivering long service life and superior protection against the elements.
