Material Upgrades

Black Oxide Coating

  • Enhanced Corrosion Resistance: Black oxide provides a protective layer that helps prevent rust and oxidation, which can extend the life of the part, especially in humid or corrosive environments.

  • Reduced Wear: The coating reduces friction between metal surfaces, which minimizes wear and tear. This is particularly important for bearings, as they are subjected to constant motion and load.

  • Improved Durability: By forming a stable layer on the surface of the metal, black oxide increases the part's resistance to fatigue and mechanical damage.

  • Reduced Service Time Less likely to fuse to the frame and headset housing allowing for easy replacement when the time comes.

Stainless Steel

  • High Chromium Content (16-18%): The chromium forms a protective layer, making the material highly resistant to rust, corrosion, and oxidation.

  • Corrosion Resistance in Wet Conditions: 440C stainless steel performs particularly well in poor, wet, or marine conditions, where moisture can cause rust in less resistant materials.

  • High Hardness: After heat treatment, 440C can reach a high level of hardness (Rockwell hardness in the upper 50s to low 60s), making it suitable for applications requiring wear resistance.

  • Reduced Service Time Less likely to fuse to the frame and headset housing allowing for easy replacement when the time comes.

ABEC 3 as Standard

Most non-bike specific bearings are ABEC 1 as standard. Blueseal Bike Bearings™ are all ABEC 3 Rated, this higher class of bearing runs smoother & last longer. 

Max. Fill Premium Grease

Standard bearings contain a small amount of basic bearing grease (Approx. 20%) which offers little protection towards corrosion and rain and dirt ingress.

Blueseal Bike Bearings™ contain the maximum fill of Mobil waterproof grease possible without compromising the function of the close-contact rubber seals.

Designed For Bicycles

Specially engineered bicycle bearings. Designed for maximum efficiency, they outperform standard bearings.

Close Contact 2RS LLB Seals

Blueseal Bike Bearings™ have top-quality LLB 2RS close-contact rubber seals. The tighter the seal is to the inner bearing race the harder for water and dirt to get in and the grease to get out!
