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.

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!
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.
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.
Designed For Bicycles
Specially engineered bicycle bearings. Designed for maximum efficiency, they outperform standard bearings.
Trailvision is an independent family business with over 15 years of hands-on experience in the bike-bearing industry. Using our expertise we develop and stock only the best products specifically suited for bicycles.
