ENDURO BEARINGS 698 LLB Bearing - ABEC 3 - 8x19x6 mm

The 698 LLB Enduro Bearings bearing is a miniature radial bearing designed for high-speed rotation applications such as pedals and small pivots. Its ABEC-3 certification guarantees rigorous dimensional precision, whilst the C3 internal clearance makes it suitable for assemblies under thermal stress or lightly preloaded.

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

This bearing is compatible with the majority of flat pedals and compact bottom bracket systems requiring a standard 698 format. Ideal as a direct OEM replacement or as a performance upgrade.

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

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

Do I need to add grease before installing it?
No, this bearing is supplied ready to use. It is sealed and factory-lubricated with the exact quantity of high-performance grease required for its service life. Opening the seal to add further grease risks damaging the sealing lip and allowing contaminants to enter.
