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.
