Enduro ball bearing in a good quality.

Size: 2231

Dimensions: 22x31x7 mm

2RS: 2 rubber seals, one on each side of the bearing.

LLU: Sealing type with a double-lip seal that, with a stronger contact in the groove, creates a labyrinth seal.

MAX: This means that it has the maximum number of balls in the bearing. The guide ring that holds the balls has been removed, for better space for the balls. These bearings can withstand up to 35% greater load. They are filled with up to 90% fat. Particularly suitable for MTB.

ABEC3 - ABEC5: The higher the number, the greater the precision the bearings are made with.
