ENDURO BEARINGS 698 LLB - ABEC 3 - 8x19x6

The 698 LLB Enduro Bearings is a miniature radial bearing designed for high-speed applications such as pedals and small pivots. Its ABEC-3 rating ensures precise dimensional accuracy, whileits C3 internal clearance makes it suitable for installations under thermal stress or with slight preload.

Its compact dimensions (8 x 19 x 6 mm) allow for installation in tight housings. The LLB design ( single-sided low-friction rubber seal) promotes smooth rotation while providing partial protection against contaminants.

This bearing is compatible with most flat pedals and compact crankset systems requiring a standard 698 size. Ideal as a direct replacement for the original or as a performance upgrade.

What is the difference between an LLB seal and an LLU seal from Enduro Bearings?
The LLB seal is designed for high-speed rotating parts such as wheel hubs, as its lips barely touch the race, offering maximum efficiency and zero perceptible friction. The LLU seal, on the other hand, is a firmer, direct-contact seal, ideal for suspension pivots that move very little but are exposed to heavy mud splashes.

How do you know when it’s time to replace this bearing?
If you remove your wheel or take off your chain and feel a hard spot, lateral play, or a grinding noise when turning the axle by hand, the balls or raceways are worn out. A worn-out bearing slows down your bike and can damage the hub if you wait too long.

Should you add grease before installing it?
No, this bearing comes ready to use. It is factory-sealed and lubricated with the exact amount of high-performance grease needed for its entire service life. Opening the seal to add more grease may damage the sealing lip and allow contaminants to enter.
