The 3903-2RS-MAX-E (3903H10-VRS-E) is a heavy-duty MAX-style cartridge bearing engineered for bicycle frame pivots and suspension linkage systems. Designed to withstand high radial loads and low-rotation movement, this bearing features an extended inner race to ensure accurate spacing and improved alignment in pivot assemblies.
The MAX ball configuration increases load capacity and durability, making this bearing ideal for high-stress suspension applications.
Key Features
-
MAX-Style Bearing – Increased ball count for superior radial load handling
-
Extended Inner Race (E) – 10mm bearing width with inner race extended to 13mm for precise pivot spacing
