Blueseal Bike Bearings™ are bicycle specific bearings
Close Contact 2RS LLB Seals
Blueseal Bike Bearings™ use top-quality LLB 2RS close-contact rubber seals. The tighter the seal is to the inner bearing race, the harder it is for water and dirt to get in — and the harder it is for grease to get out.
Max. Fill Premium Grease
Standard bearings contain a small amount of basic grease (around 20%), offering limited protection against corrosion, rain, and dirt ingress.
Blueseal Bike Bearings™ contain the maximum fill of Mobil waterproof grease possible, without compromising the function of close-contact rubber seals.
ABEC 3 as Standard
Most non-bike-specific bearings are ABEC 1. Blueseal Bike Bearings™ are ABEC 3 rated, running smoother and lasting longer.
Designed For Bicycles
These are not general-purpose industrial bearings — Blueseal Bike Bearings™ are engineered specifically for bicycles, optimised for load, smoothness, and durability. They outperform standard bearings in both efficiency and lifespan.
