Enduro Bearing 15x28x7mm 7902 ZS MAX
What Is It?
The Enduro 7902 ZS MAX bearing (15x28x7mm) is a high-performance sealed cartridge bearing commonly used in MTB headset systems (ZeroStack / ZS), suspension pivots, and frame linkage applications.
The “7902” is the bearing designation, while 15x28x7mm is the standard size. The ZS MAX version combines a headset-oriented application (ZS) with Enduro’s MAX design, which is optimized for high load and impact resistance rather than ultra-smooth spinning.
Key Features
- High-load sealed cartridge bearing
- MAX design (full complement of balls, no cage) for maximum strength
- Standard 7902 bearing size: 15 x 28 x 7 mm
- Designed for MTB headset and frame load zones
- Rubber seals to protect against dirt, water, and contamination
- Pre-greased for durability and low maintenance
- Excellent resistance to shock and side loads
- Built for aggressive MTB riding conditions

MAX vs Standard (Important)
- MAX bearing: more balls → higher load capacity → better for pivots/headsets
- Standard bearing: fewer balls → smoother rotation → better for hubs
