6903 LLU MAX BO – MAX-Design, Black-Oxide, Radial Suspension Bearing
Dimensions: 17 mm × 30 mm × 7 mm

Description:
The Enduro 6903 LLU MAX BO bearing is engineered for extreme durability in mountain-bike suspension pivots and other high-load applications. Enduro pioneered MAX-type bearings over 20 years ago to handle the multi-directional stresses of bicycle pivots, offering 35–40 % greater load capacity than standard radial bearings.

Design Features:

·         MAX-Design: Deep-groove races accommodate the maximum number of Grade 10 balls for superior load distribution.

·         Black-Oxide (BO) Treatment: Magnetite surface coating enhances corrosion resistance and extends service life.

·         Sealing System: Dual-lip LLU seals form a full labyrinth barrier against contaminants while retaining lubricant.

·         Lubrication: Factory-filled with 90 % Almagard® high-pressure grease for long-term, smooth operation.

·         Material Options: Available in high-carbon chromium steel, 440C stainless, ceramic-hybrid, or XD15 stainless with ceramic/stainless balls.

Specifications:

·         Static Load Rating: 763 lbf (3.39 kN)

·         Weight: 17.59 g

·         Common Equivalent Part Numbers: W272452, 300020001

Applications:

·         Mountain-bike suspension pivot points

·         Other compact, high-load rotational assemblies
