6804 Premium Bearing | NON-CONTACT SEAL LLB |
Inner x Outer x Depth (mm): 20 x 32 x 7mm
Used on: Wheels
Seals: LLB non contacting ultra low friction seals, where the seal does not contact the rotating parts. Use where rotation speed is most important (usually racing). If bearing longevity is more important and you use your bike in harsh conditions frequently, then our contacting seal version of this bearing (LLU Seals) might be more appropriate.
These high end precision bearings with ultra low friction seals are a viable alternative to hybrid ceramic bearings, and what we would recommend (instead of hybrid ceramic).
