‚ Seal Design
Blueseal Bike Bearings‚ have top-quality rubber seals. The‚ better the seal harder it is for water and dirt to get in and the grease to get out! This is the most important feature of a bike bearing.
Premium Grease‚
Blueseal Bike Bearings‚ contain‚ Mobil XHP 222‚ grease.‚ Standard stock bearings are designed for use in machinery and contain very little amounts of non-specific bearing grease (Approx. 20%) This offers little protection against rain and dirt ingress.
‚
Premium Waterproof Grease
Mobil XHP 222‚ is a premium marine-specific grease with high washout resistance that is designed for use in poor conditions. This means the grease stays in the bearing for longer and offers the best protection against dirt, rain and muddy water.
‚
Strong Composition
Blueseal Bike Bearings‚ are built using the best quality materials, this higher class of bearing‚ run smoother & last longer.‚

Blueseal Bike Bearings™ are Bicycle Specific Bearings
Close Contact 2RS LLU Seals
Blueseal Bike Bearings™ use top-quality LLU 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 escape.
Max. Fill Premium Grease
Standard bearings contain around 20% generic grease, offering limited resistance against rain, corrosion, and dirt ingress.
Blueseal Bike Bearings™ contain the maximum possible fill of premium Mobil waterproof grease without compromising seal function.
ABEC 3 as Standard
Most non-bike-specific bearings are ABEC 1. Blueseal Bike Bearings™ are ABEC 3 rated, providing smoother running and longer lifespan.
MAX Bearings — 40% Stronger
MAX full complement bearings contain no retaining cage, allowing for a maximum number of ball bearings.
This increases both radial and axial load capacity by up to 40% compared to standard bearings.
