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!

Good product and customer service

Very happy with the product and excellent customer service when the was an issue with the order

S/S headset kit for stumpjumper fsr

Well overdue headset and fork overhaul/service revealed a seriously nasty looking top bearing. I knew things felt a little rough but did not expect to find things looking quite that baddd. New s/s bearing kit top and bottom, great fit, steering like silk again!
Will defo consider using for new pivot bearings in the future…
Kinda’ expected the bearings to have a ‘blue seal’ but i guess thats really not important so yea;
Thumbs up.

Prompt quality service and product

The headset bearings work a treat so far. Time will tell if the stainless steel option I chose has the presumed benefits. Great service.

Quality product. Great communication. Excellent delivery

Lots of help at hand

I was really struggling and confused with bearing sizes for my frame. Tom went the extra mile to help me get to the bottom of what was required. It wasn’t straightforward as the bike manual had the incorrect sizes listed.
I’ve now installed the new bearings and the bike is running smoother than new.
