Overview
Is the Enduro 7902 1ZS MAX the right suspension pivot bearing for your mountain bike?
The Enduro 7902 1ZS MAX Greasable Angular Contact Bearing is a purpose-built suspension pivot bearing engineered specifically for the demands of mountain bike linkages. Enduro pioneered MAX-type bearing design over 20 years ago to address the unique challenges of suspension pivots, and this 15x28x7mm bearing delivers 35-40% more load capacity than standard radial bearings by packing the maximum possible number of Grade 10 balls into the races via a custom ground fill slot. Deep-groove race design provides the lateral support needed to handle the twisting and multi-directional forces that destroy conventional bearings under hard trail and enduro use. The bearing ships pre-filled with 90% Almagard extra high pressure grease and should be installed with the shield facing out.
The 1ZS configuration features a single shield on one side, keeping the bearing greasable from the open face for easy maintenance without full bearing replacement. As an Angular Contact design, the bearing engages all balls across the contact surface when properly installed, spreading load over a larger area to minimize wear and extend service life. ABEC-3 tolerance rating ensures consistent dimensional accuracy for reliable fit across compatible suspension platforms. This bearing is a direct replacement for Santa Cruz and Intense frame pivots, and is compatible with any frame specifying a 15x28x7mm suspension bearing.

FAQ
Good questions
Get to know Enduro
There's more to Enduro than this one product. Our Enduro page has the full Enduro lineup we carry and more about the brand.
Visit the Enduro page →What makes MAX-type bearings better for suspension pivots?
MAX-type bearings use a custom ground fill slot in the races to pack in the maximum possible number of balls, giving 35-40% more load capacity than a standard radial bearing of the same size. The deeper race grooves also provide greater lateral support for the multi-directional forces at suspension pivot points, which quickly damage conventional bearings.
What does the 1ZS designation mean and why does it matter?
The 1ZS designation means the bearing has a single shield on one side and is open on the other, allowing you to inject fresh grease through the open face without removing the bearing. This extends service intervals and bearing life significantly compared to fully sealed 2RS bearings, which must be replaced when the grease breaks down.
Which way does the shield face during installation?
Install this bearing with the shield facing outward, away from the pivot hardware. Enduro specifies this orientation to keep the open greasing face accessible and to ensure the labyrinth seal on the shielded side faces the correct direction for debris protection.
