ENDURO BEARINGS 61903 LLU/LLB CN A5 - ABEC 5 - 17x30x7

The 61903 LLU/LLB CN Enduro Bearings is an ABEC-5 radial hub bearing with normal clearance (CN) and dimensions of 17 x 30 x 7 mm. Its ABEC-5 precision and CN clearance make it ideal for high-performance hubs requiring precise rotation.

CN (normal) clearance is optimal for precision applications without high thermal stress. ABEC-5 certification guarantees superior concentricity and rotational smoothness. Available in LLU or LLB seals depending on the desired level of sealing and friction.

Suitable for high-precision wheel hubs with a 17 mm bore. Enduro Bearings’ ABEC-5 quality guarantees superior rotational performance for the most demanding cyclists.
